The Speech Studio Voice Gallery includes additional information such as age groups, personality, and scenarios. However, when using the SDK or REST API to retrieve voices, only a limited set of properties is available. Are these additional properties accessible through the SDK or API? The /texttospeech/acc/v3.0-beta1/vcg/voices API endpoint used by the gallery is undocumented, and attempts to call it with a subscription ID result in a 404 error.

Thank you for reaching out to Microsoft Q&A forum!
Currently, the Azure Speech SDK and REST API only provide basic properties for voices, such as name, locale, and gender. The additional details shown in the Speech Studio Voice Gallery are not exposed through the public API or SDK.
The
/texttospeech/acc/v3.0-beta1/vcg/voicesendpoint you mentioned is likely an internal, undocumented API, which is why it's not accessible.If you’re looking for specific voice characteristics like styles or roles, you can use SSML with the
mstts:express-astag. This lets you adjust the speaking style for supported neural voices.Thank you.

2025-02-10T13:55:15.2966667+00:00 @santoshkc Yes - you've clarified that this additional information is unavailable. I am aware of the
mstts:express-astag but the documentation seems to indicate that not all voices support all styles and roles. The speech gallery includes the list of supported (or possibly recommended) roles/styles for each voice which would be useful information.Thanks for following up!
