- A UN study earlier this year suggested that when smart assistants like Google Assistant, Apple's Siri, and Amazon's Alexa use female voices, it only reinforces gender biases.
- Google says that it wanted to add a male voice to Google Assistant when it first launched, but technological constraints meant that it was easier to work with female voices.
- Google is now using better and more efficient technology, called WaveNet, that makes it easier for Google to add voices - including male voices - to Google Assistant.

Earlier this year, a United Nations Education, Scientific and Cultural Organization (UNESCO) study suggested that voice assistants like Apple's Siri, Amazon's Alexa, and Google's Assistant were perpetuating "harmful gender biases," as the assistant's default voices were all female.The study, as well as those before it with similar suggestions, had a point. Female voices on voice assistants could, indeed, perpetuate the old-fashioned bias that women were there to be "assistants," rather than the assisted. Advertisement
You asked a question or issued a command, and your smart assistant's female voice would oblige. The experience's vibes hark back to lesser days when women held more subservient roles than men.
"When we first launched our assistant, we wanted to use a male voice," Google Assistant product manager Brant Ward told Business Insider.When Google Assistant was first being developed, Ward told Business Insider that the traditional TTS systems simply worked better with female voices than it did with male voices."At the time, the guidance was the technology performed better for a female voice," Ward said, "The TTS systems in the early days kind of echoed [early systems] and just became kind of more tuned to female voices."Advertisement
Specifically, the typically higher pitch in female voices were more intelligible in early TTS systems because they had a more limited frequency response, Ward says. In English: voices that didn't come from a human were easier to understand if they took on female characteristics.
Amazon's Alexa smart assistant also started off life with a female voice. The company responded to previous studies that female smart assistant voices perpetuated a gender bias by saying that female voices were just generally more pleasing."We carried out research and found that a woman's voice is more 'sympathetic' and better received," said head of Amazon's "Smart Home" division, Daniel Rausch, in a conversation with Business Insider back in September last year.

We asked Apple if there was any reason why Siri had a female voice at launch, but the company did not have anything to add before this story was published.
These days, Google doesn't use the older TTS system that was at work in the first iteration of Google Assistant. The company moved to the WaveNet technology, created by DeepMind, Google's British AI subsidiary. WaveNet is essentially a better and more efficient system that makes it easier for Google to add more voices to Google Assistant.Today, Google Assistant has 11 different voices in the US with a range of male and female options.Advertisement
On Wednesday, Google announced that it's releasing a new voices for different languages, including German, French, Dutch, Norwegian, Japanese, and even English-speaking voices with a British or Indian accent. And for Italian and Korean, where Google Assistant is only available in male's voice so far, it's getting a female voice for the first time.
