Hi @Barton, Pina , Thanks for using Microsoft Q&A Platform.
Unfortunately, VALL-E is not available for any form of public consumption at this time. As we know VALL-E is a research project; so, there is no customer onboarding queue or providing access or adding to any kind of waitlist.
Additionally, if you are interested, you can try Custom Neural Voice: Speech Studio - Microsoft Azure and here is the documentation: https://learn.microsoft.com/en-us/azure/cognitive-services/speech-service/custom-neural-voice
Have you submitted for Custom neural voice request?
I hope this helps.
