Apple is adding two new voices to Siri’s English offerings, and eliminating the default ‘female voice’ selection in the latest beta version of iOS. This means that every person setting up Siri will choose a voice for themselves and it will no longer default to the voice assistant being female, a topic that has come up quite a bit with regards to bias in voice interfaces over the past few years.

The beta version should be live now and available to program participants.
