“Q, which debuted on Monday at South by Southwest in Austin, Texas, is a composite of dozens of voices of people who identify as non-binary. To create the voice, Virtue and partners including Pride Copenhagen, linguists and technologists recorded the voices before creating a composite of all of them. The team then had 4,500 people in several European countries listen to the voice before identifying what sounded the most gender-neutral.”
