This paper was originally published as part of a report jointly produced by Brookings and the Italian Institute for International Political Studies (ISPI), entitled “AI in the Age of Cyber-Disorder.” This report is also part of “AI Governance,” a series from The Brookings Institution’s Artificial Intelligence and Emerging Technology (AIET) Initiative that identifies key governance and norm issues related to AI and proposes policy remedies to address the complex challenges associated with emerging technologies.

The world may soon have more voice assistants than people—yet another indicator of the rapid, large-scale adoption of artificial intelligence (AI) across many fields. The benefits of AI are significant: it can drive efficiency, innovation, and cost-savings in the workforce and in daily life. Nonetheless, AI presents concerns over bias, automation, and human safety which could add to historical social and economic inequalities.

One particular area deserving greater attention is the manner in which AI bots and voice assistants promote unfair gender stereotypes. Around the world, various customer-facing service robots, such as automated hotel staff, waiters, bartenders, security guards, and child care providers, feature gendered names, voices, or appearances. In the United States, Siri, Alexa, Cortana, and Google Assistant—which collectively total an estimated 92.4% of U.S. market share for smartphone assistants—have traditionally featured female-sounding voices.

As artificial bots and voice assistants become more prevalent, it is crucial to evaluate how they depict and reinforce existing gender-job stereotypes and how the composition of their development teams affect these portrayals. AI ethicist Josie Young recently said that “when we add a human name, face, or voice [to technology] … it reflects the biases in the viewpoints of the teams that built it,” reflecting growing academic and civil commentary on this topic. Going forward, the need for clearer social and ethical standards regarding the depiction of gender in artificial bots will only increase as they become more numerous and technologically advanced.

Given their early adoption in the mass consumer market, U.S. voice assistants present a practical example of how AI bots prompt fundamental criticisms about gender representation and how tech companies have addressed these challenges. In this report, we review the history of voice assistants, gender bias, the diversity of the tech workforce, and recent developments regarding gender portrayals in voice assistants. We close by making recommendations for the U.S. public and private sectors to mitigate harmful gender portrayals in AI bots and voice assistants.


The history of AI bots and voice assistants

The field of speech robotics has undergone significant advancements since the 1950s. Two of the earliest voice-activated assistants, phone dialer Audrey and voice calculator Shoebox, could understand spoken numbers zero through nine and limited commands but could not verbally respond in turn. In the 1990s, speech recognition products entered the consumer market with Dragon Dictate, a software program that transcribed spoken words into typed text. It wasn’t until the 2010s that modern, AI-enabled voice assistants reached the mass consumer market—beginning in 2011 with Apple’s Siri and followed by Amazon’s Alexa, Google Assistant, and Microsoft’s Cortana, among others. In conjunction with the consumer market, voice assistants have also broken into mainstream culture, exemplified by IBM’s Watson becoming a “Jeopardy!” champion or a fictional virtual assistant named Samantha starring as the romantic interest in Spike Jonze’s 2013 film “Her.”

While the 2010s encapsulated the rise of the voice assistant, the 2020s are expected to feature more integration of voice-based AI. By some estimates, the number of voice assistants in use will triple from 2018 to 2023, reaching 8 billion devices globally. In addition, several studies indicate that the COVID-19 pandemic has increased the frequency with which voice assistant owners use their devices due to more time spent at home, prompting further integration with these products.

Voice assistants play a unique role in society; as both technology and social interactions evolve, recent research suggests that users view them as somewhere between human and object. While this phenomenon may somewhat vary by product type—people use smart speakers and smartphone assistants in different manners—their deployment is likely to accelerate in coming years.

The problem of gender biases

Gender has historically led to significant economic and social disparities. Even today, gender-related stereotypes shape normative expectations for women in the workplace; there is significant academic research to indicate that helpfulness and altruism are perceived as feminine traits in the United States, while leadership and authority are associated with masculinity. These norms are especially harmful for non-binary individuals as they reinforce the notion that gender is a strict binary associated with certain traits.

These biases also contribute to an outcome researchers call the “tightrope effect,” where women are expected to assume traditionally “feminine” qualities to be liked, but must simultaneously take on—and be penalized for—prescriptively “masculine” qualities, like assertiveness, to be promoted. As a result, women are more likely to both offer and be asked to perform extra work, particularly administrative work—and these “non-promotable tasks” are expected of women but deemed optional for men. In a 2016 survey, female engineers were twice as likely, compared to male engineers, to report performing a disproportionate share of this clerical work outside their job duties.

Sexual harassment or assault is another serious concern within technology companies and the overall U.S. workforce. A 2015 survey of senior-level female employees in Silicon Valley found that 60% had experienced unwanted sexual harassment and one-third had feared for their safety at one point. This problem is exemplified by a recent series of high-profile sexual harassment and gender discrimination allegations or lawsuits in Silicon Valley, including claims against Uber that led to a $4.4 million settlement with the Equal Employment Opportunity Commission (EEOC) and the resignation of former CEO Travis Kalanick.

The lack of diversity in the technology industry

Any analysis of AI bots should consider the diversity and associated biases of the teams that design them. In a 2019 AI Now Institute report, Sarah Myers West et al. outlined the demographic make-up of technology companies and described how algorithms can become a “feedback loop” based on the experiences and demographics of the developers who create it. In her book “Race After Technology,” Princeton professor Ruha Benjamin described how apparent technology glitches, such as Google Maps verbally referring to Malcolm X as “Malcolm Ten,” are actually design flaws born from homogenous teams.

“Any analysis of AI bots should consider the diversity and associated biases of the teams that design them.”

In addition to designing more reliable products, diverse teams can be financially profitable. In a 2015 McKinsey study, companies in the upper quartile of either ethnic or gender diversity were more likely to have financial returns above their industry mean, while those in the bottom quartile lagged behind the industry average. The relationship between diversity and profit was linear: every 10% increase in the racial diversity of leadership was correlated with 0.8% higher earnings.

Despite the benefits of diverse teams, there is a lack of diversity within the STEM pipeline and workforce. In 2015, approximately 19.9% of students graduating with a U.S. bachelor’s degree in engineering identified as women, up from 19.3% in 2006. Meanwhile, about 18.7% of software developers and 22.8% of computer hardware engineers currently identify as women in the United States. The same is true of companies leading AI development—Google, for instance, reported that its global percentage of women in technical roles increased from 16.6% in 2014 to 23.6% in 2020 (meanwhile, Google’s global percentage of women grew from 30.6% to 32.0% over the same time period). While this increase demonstrates progress, it is still far from parity for these positions. Similarly, neither Apple, Microsoft, nor Amazon have achieved an equal gender breakdown in their technical or total workforces—and overall, Black and Latinx women hold fewer than 1.5% of leadership positions in Silicon Valley.

How gender is portrayed in AI bots

In the 1990s, Stanford researchers Byron Reeves and Clifford Nass found that individuals exhibited similar behaviors with televisions and computers as they did with other humans: not only did they treat the machines with respect, but they also interacted with male-sounding and female-sounding computer voices differently based on gender stereotypes.

“[A]long with the humanization of technology comes questions of gender representation, including how to depict gender characteristics.”

Since then, the rise of artificial intelligence has only deepened the bond between humans and technology. AI can simulate human voices, linguistic patterns, personalities, and appearances; assume roles or tasks traditionally belonging to humans; and, conceivably, accelerate the integration of technology into everyday life. In this context, it is not illogical for companies to harness AI to incorporate human-like characteristics into consumer-facing products—doing so may strengthen the relationship between user and device. In August 2017, Google and Peerless Insights reported that 41% of users felt that their voice-activated speakers were like another person or friend.

But along with the humanization of technology comes questions of gender representation, including how to depict gender characteristics, how to teach AI to respond to gender-based harassment, and how to improve the diversity of AI developers. While recent progress in these areas reflect their growing importance in the industry, there is still much room for improvement.

Both direct and indirect gender attributions broadcast stereotypes

Some AI robots or digital assistants clearly assume a traditional “male” or “female” gender identity. Harmony, a sex robot who can quote Shakespeare, assumes the likeness of a cisgender Caucasian woman down to intimate detail, and the life-size robot Albert Einstein HUBO similarly resembles the late physicist.

But others evoke gender in less direct ways. There are over three billion voice assistants in use around the world, according to Juniper Research, none of which adopt a physical human-like appearance. Instead, these bots conjure assumptions of gender through provided information such as a gender-aligned name (like Audrey or Alexa) or with conversational responses.

To learn how modern voice assistants respond to direct queries about gender, we asked four of the most popular voice assistants on the market—Siri, Alexa, Cortana, and Google Assistant—about their gender identities. We specifically chose to ask both open-ended and direct questions to understand the concepts programmed into the AI. We also asked if the voice assistants identified as non-binary to provide an option outside the traditional gender binary.

All four voice assistants declined to verbally acknowledge any gender identity (Table A). Siri and Google Assistant responded that they do not have a gender, while Alexa and Cortana added that they are AI, which means they exist outside of gender. Similarly, when we asked Google Assistant “what is your gender,” its dissenting response came with a follow-up question labelled “why don’t you have a gender,” to which it responded “well, maybe because I’m software, not a person.”

Table A: Voice Assistant Responses to Gender Identification Questions

But even voice assistants that avoid direct gender adherence still come with gendered—and historically female-sounding—voices. Alexa, Cortana, Siri, and Google Assistant originally launched with female-sounding default voices, although all four have since been updated. Alexa’s only universal voice is still female-sounding, but users have the option of purchasing celebrity voices, including those of male celebrities, for limited features. Cortana added its first male-sounding voice earlier this year but has retained a female-sounding voice default. Siri currently has both “male” and “female” voice options for 34 out of 41 language settings but defaults to “female” for approximately 27 of the 34, including U.S. English. Google, on the other hand, has updated its voice technology to randomly assign default voice options and center voices around color names like “red” or “orange” instead of traditional gender labels.

“[T]he prominence of female-sounding voice assistants encourages stereotypes of women as submissive and compliant.”

These voice settings are significant because multiple academic studies have suggested that gendered voices can shape users’ attitudes or perceptions of a person or situation. Furthermore, as Nass et al. found, gendered computer voices alone are enough to elicit gender-stereotypic behaviors from users—even when isolated from all other gender cues, such as appearance. Mark West et al. concluded in a 2019 UNESCO report that the prominence of female-sounding voice assistants encourages stereotypes of women as submissive and compliant, and UCLA professor Safiya Noble said in 2018 that they can “function as powerful socialization tools, and teach people, in particular children, about the role of women, girls, and people who are gendered female to respond on demand.”

These voice-gender associations have even cemented a place in pop culture. For instance, when Raj, a character on “The Big Bang Theory” who has a hard time speaking to women, encounters Siri on his new iPhone, he treats “her” as a quasi-girlfriend by “dressing” her for dinner and asking her to call him “sexy.” In an ensuing dream, which personifies Siri as a beautiful young woman, she offers to sleep with him if he only asks.

Companies need to address gender-based harassment in AI bots

As technology companies come under increasing scrutiny for their response to online harassment and hate speech, social media platforms like Facebook and YouTube have invested billions of dollars in AI systems that automatically monitor content and remove hateful or violent posts. In a House Antitrust Subcommittee hearing in July 2020, Facebook CEO Mark Zuckerberg testified that Facebook can identify approximately 89% of hate speech before it is user-reported.

In a similar vein, as AI robots and voice assistants become more advanced and realistic (e.g., through Emotion AI, natural language processing, and more), developers will need to confront how they respond to hate speech or harassment in automated conversation, by programming responses that clearly and directly tackle unacceptable speech.

Voice assistants illustrate how Silicon Valley’s approach to gender-based harassment is evolving. In 2017, Leah Fessler of Quartz analyzed how Siri, Alexa, Cortana, and Google Assistant responded to flirty, sexual comments and found they were evasive, subservient, and sometimes seemingly thankful (Table B). When replicating this exercise in July 2020, we discovered that each of the four voice assistants had since received a rewrite to respond to harassment in a more definitively negative manner. For example, Cortana responded by reminding the user she is a piece of technology (“I’m code”) or moving on entirely. Similarly, Siri asked for a different prompt or explicitly refused to answer.

Considerations when addressing harassment toward voice assistants

It is vital to point out and address how AI assistants respond to harassment and hate speech—especially when related to gender and other historically marginalized classes. AI can play both a descriptive and prescriptive role in society: it is possible for digital assistants to both reflect the norms of their time and place, while also transmitting them to users through their programmed responses. According to robotic intelligence company Robin Labs, at least 5% of digital assistant inquiries are sexually explicit in nature. If technology functions as a “powerful socialization tool,” as Noble argues, the positive or negative responses of voice assistants can reinforce the idea that harassing comments are appropriate or inappropriate to say in the offline space. This is particularly true if people associate bots with specific genders and alter their conversation to reflect that.

“[T]he positive or negative responses of voice assistants can reinforce the idea that harassing comments are appropriate or inappropriate to say in the offline space.”

Additionally, existing and future artificial bots must be held accountable for errors or bias in their content moderation algorithms. Voice assistants are a common source of information; in 2019, Microsoft reported that 72% of survey respondents at least occasionally conduct internet searches through voice assistants. However, speech recognition software is prone to errors. For example, in 2019, Emily Couvillon Alagha et al. found that Google Assistant, Siri, and Alexa varied in their abilities to understand user questions about vaccines and provide reliable sources. The same year, Allison Koenecke et al. tested the abilities of common speech recognition systems to recognize and transcribe spoken language and discovered a 16 percentage point gap in accuracy between Black participants’ voices and white participants’ voices. As artificial bots continue to develop, it is beneficial to understand errors in speech recognition or response—and how linguistic or cultural word patterns, accents, or perhaps vocal tone or pitch may influence an artificial bots’ interpretation of speech. The benefits of rejecting inappropriate or harassing speech are accompanied by the need for fairness and accuracy in content moderation. Particular attention should be given to disparate accuracy rates by users’ demographic characteristics.

Recommendations to address gender biases incorporated in AI bots

While voice assistants have the potential for beneficial innovation, the prescriptive nature of human-like technology comes with the necessity of addressing the implicit gender biases they portray.

Voice technology is relatively new—Siri, Cortana, Alexa, and Google Assistant were first launched between 2011 and 2016 and continue to undergo frequent software updates. In addition to routine updates or bug fixes, there are additional actions that the private sector, government, and civil society should consider to shape our collective perceptions of gender and artificial intelligence. Below, we organize these possible imperatives into actions and goals for companies and governments to pursue.

1. Develop industry-wide standards for the humanization of AI (and how gender is portrayed).

According to a 2016 Business Insider survey, 80% of businesses worldwide use or are interested in using consumer-facing chatbots for services such as sales or customer service. Still, there are no industry-wide guidelines regarding if or when to humanize AI. While some companies, such as Google, have elected to offer multiple voice options or choose gender-neutral product names, others have opted to incorporate gender-specific names, voices, appearances, or other features within bots. To provide guidance for current or future products, businesses would benefit from industry standards to address gender characteristics in AI, which should be developed with input from academia, civil society, and civil liberties groups. Such standards should include:

  • Active contributions from AI developers and teams who reflect diverse populations in the United States, including diversity of gender identity, sexual orientation, race, ethnicity, socioeconomic background, and location.
  • Mandates for companies to build diverse developer teams and promote input from underrepresented groups.
  • Guidelines surrounding the humanization of AI: when it is appropriate to do so and what developmental research is needed to mitigate bias or stereotype reinforcement.
  • Definitions of “female,” “male,” “gender-neutral,” “gender-ambiguous,” and “non-binary” human voices—and when each would be appropriate to use.
  • Definitions of gender-based harassment and sexual harassment in the context of automated bots or voice assistants. Guidelines for how bots should respond when such harassment occurs and analysis of the consequences of offering no response, negative responses, support or helpline information, or other reactions.
  • Methods for companies to reduce algorithmic bias in content moderation or programmed conversational responses.
  • Achievable metrics for accuracy in speech recognition, including identification of gender-based harassment.
  • Methods to hold companies accountable for false positives and negatives, accuracy rates, and bias enforcement, including the exploration of an independent review board to confirm reported data.
  • Consideration of current societal norms and their impact on interactions with AI bots or voice assistants.
  • Ways to address differing cultural standards in conversation, especially when developing voice assistants to be deployed in multiple countries.

2. Encourage companies to collect and publish data relating to gender and diversity in their products and teams.

Real-world information is extremely valuable to help researchers quantify and analyze the relationship between technology, artificial intelligence, and gender issues. While more data would be beneficial to this research, it would also require some degree of transparency from technology companies. As a starting point, academia, civil society, and the general public would benefit from enhanced insight into three general areas.

First, technology companies should publicly disclose the demographic composition of their AI development teams. Google, Apple, Amazon, and Microsoft each release general data featuring the gender and racial breakdowns of their overall workforce. While they have broadly increased hiring of female and underrepresented minorities compared to prior years, they have a long way to go in diversifying their technical staff. Publishing topline numbers is a good start, but companies should further increase transparency by releasing their breakdown of employees in specific professional positions by gender, race, and geographic location. This reporting should focus on professions that have historically seen deep gender divisions, such as AI development, AI research, human resources, marketing, and administrative or office support. Disclosing this data would allow users to better understand the teams that develop voice assistants and hold companies accountable for their hiring and retention policies.

Second, technology companies should release market research findings for current AI bots, such as consumer preferences for voices. In 2017, Amazon said it chose Alexa’s female-sounding voice after receiving feedback from internal focus groups and customers, but there is little publicly available information about these studies other than mentions in media reports. Market research is common—and influential—for many products and services, but companies rarely release data related to methodology, demographic composition of researchers and participants, findings, and conclusions. This information would add to existing research on human perceptions of gendered voices, while also providing another layer of transparency in the development of popular products.

Third, technology companies can contribute to research on gender-neutral AI voices, which in turn could help avoid normative bias or binary stereotypes. Previous cases indicate that users tend to project gender identities onto intentionally gender-neutral technology—for example, a team of researchers developed a gender-ambiguous digital voice called Q in 2019, but some YouTube commenters still ascribed a specific gender to Q’s voice. Additionally, when conducting studies with humanoid, genderless robots, Yale researcher Brian Scassellati observed that study participants would address the robots as “he” or “she” even though the researchers themselves used “it.” Although additional research into the technical nuances and limitations of building artificial voices may be necessary before truly gender-neutral AI is possible, technology companies can help shine light on whether users change their queries or behavior depending on the gender or gender-neutrality of voice assistants. Technology companies have access to an unparalleled amount of data regarding how users treat voice assistants based on perceived gender cues, which include the nature and frequency of questions asked. Sharing and applying this data would revolutionize attempts to create gender-neutral voices and understand harassment and stereotype reinforcement toward voice assistants.

3. Reduce barriers to entry—especially those which disproportionately affect women, transgender, or non-binary individuals—for students to access a STEM education.

The underrepresentation of women, transgender, and non-binary individuals in AI classrooms inhibits the development of a diverse technical workforce that can address complex gender issues in artificial bots. Although academic researchers have identified several challenges to education that disproportionately affect women and have proposed actions to help mitigate them, these conclusions vary by the students’ level of education, geographic location, and other factors—and there are far fewer studies on issues affecting non-cisgender communities.

Therefore, it is important to continue to research and identify the challenges that women, transgender, and non-binary individuals disproportionately face in education, as well as how demographic factors such as race and income intersect with enrollment or performance. It is then equally important to take steps to mitigate these barriers—for instance, to address the gender imbalance in child care responsibilities among student-parents, universities may explore the feasibility of free child care programs. Furthermore, increasing the number of learning channels available to students—including internships, peer-to-peer learning, remote learning, and lifelong learning initiatives—may positively impact access and representation.

“To make STEM class content more inclusive, women, transgender, and non-binary individuals must play primary roles in developing and evaluating course materials.”

In addition, the dearth of gender diversity in AI development requires a closer look at STEM courses more narrowly. To make STEM class content more inclusive, women, transgender, and non-binary individuals must play primary roles in developing and evaluating course materials. To encourage more diversity in STEM, we must understand students’ motivations for entering STEM fields and tailor the curriculum to address them. Furthermore, universities should implement courses on bias in AI and technology, similar to those offered at some medical schools, as part of the curriculum for STEM majors. Finally, universities should reevaluate introductory coursework or STEM major admission requirements to encourage students from underrepresented backgrounds to apply.

4. To address gender disparities in society, adopt policies that allow women to succeed in STEM careers—but also in public policy, law, academia, business, and other fields.

According to data from the Society of Women Engineers, 30% of women who leave engineering careers cite workplace climate as a reason for doing so. Still, research suggests that consumers themselves exhibit gendered preferences for voices or robots, demonstrating that gender biases are not limited to technology companies or AI development teams. Because gender dynamics are often influential both inside and out of the office, change is required across many facets of the U.S. workforce and society.

At the hiring level, recruiters must evaluate gender biases in targeted job advertising, eliminate gendered language in job postings, and remove unnecessary job requisites that may discourage women or other underrepresented groups from applying. Even after women, transgender, and non-binary individuals are hired, companies must raise awareness of unconscious bias and encourage discussions about gender in the workplace. Some companies have adopted inclusive practices which should become more widespread, such as encouraging employees to share their pronouns, including non-binary employees in diversity reports, and equally dividing administrative work.

Long-Term Goals

– Increase gender representation in engineering positions, especially AI development.

– Increase public understanding of the relationship between AI products and gender issues.

– Reduce unconscious bias in the workplace.

– Normalize gender as a non-binary concept, including in the recruitment process, workplace culture, and product development and release.

– Decrease barriers to education that may disproportionately affect women, transgender, or non-binary individuals, and especially for AI courses.

– Reduce unconscious bias in government and society.


Discussions of gender are vital to creating socially beneficial AI. Despite being less than a decade old, modern voice assistants require particular scrutiny due to widespread consumer adoption and a societal tendency to anthropomorphize these objects by assigning gender. To address gender portrayals in AI bots, developers must focus on diversifying their engineering teams; schools and governments must remove barriers to STEM education for underrepresented groups; industry-wide standards for gender in AI bots must be developed; and tech companies must increase transparency. Voice assistants will not be the last popular AI bot—but the sooner we normalize questioning gender representation in these products, the easier it will be to continue these conversations as future AI emerges.
