@FJ123 You can use the voice in different regions by looking up the following API for long audio:
https://<region-short-name>.customvoice.api.speech.microsoft.com/api/texttospeech/v3.0/longaudiosynthesis/voices
The API for short audio is:
https://<region-short-name>.tts.speech.microsoft.com/cognitiveservices/voices/list
For example, the voice is listed in West Europe when you run the GET query for above with the header Ocp-Apim-Subscription-Key:<key>
.
https://westeurope.tts.speech.microsoft.com/cognitiveservices/voices/list
You can try to use the voice in different region and check if it sounds consistent. Based on feedback received for voices the team updates the voice list from time to time. If the voice sounds good in one region and the other region has some static then it is most likely a technical issue with the API endpoint and this needs to be corrected by the product service team.
I hope this helps!!
