Hello @Cal Shin
Thanks for reaching out to us, currently VALL-E product is for researching only and not a public product. But it will be releasing in the near future with no ETA as for now.
For your purpose, I may recommend you try Custom Neural Voice to see if that meets your requirements.
Speech Studio - Microsoft Azure
Blog - link
That's the GA service that helps customers create branded or personal voices also ‘Neural – cross lingual.
I am sorry for the inconvenience due to unpublic project, and I hope Speech service can meet your requirements.
Regards,
Yutong
