Upcoming changes to "Alice" Text To Speech voices

Starting 26 June 2023, “Alice” voices will no longer be supported for Text-To-Speech. Any request for “Alice” voices will be redirected to an alternative voice. No action is required from customers and no service disruption is expected.

Going forward, requests for “Alice” voices will be automatically mapped to the existing “Woman” voices when available for the selected language, and requests for non-available languages would be mapped to a paid alternative.

It is recommended to update configuration in Console, Studio flows and application to remove any references to “Alice”. Alternatively, Twilio encourages to review and re-test applications currently using “Alice” with the re-mapped voices to confirm that they work as intended.
