Hello @Roasted Phoenix LLC @Oxueillirep
I am sorry for your experinece again, I just got confirmation from product manager of TTS, the voice of Davis and other voices are in private preview but by mistake the engineering team showed it to public. When they found the bug, they rerolled the release. I am sorry about that, the engineering team will target releasing it on May 9th, please stay tuned.
In the future, the engineering team will avoid same issue happens again, they will not delete any existing voice unless officially announced deprecation. Please let us know if you still have any concern. Thanks.
