Hello @Jon Adams , Thanks for using Microsoft Q&A Platform.
Sorry for the inconveniences caused.
The neural voice
en-US-BlueNeural
(Neutral)
is available in public preview. Voices and styles in public preview are only available in these service regions: East US, West Europe, and Southeast Asia.
The en-US-BlueNeural (Neutral)
voice is currently available exclusively in those regions. Therefore, please ensure to create an Azure resource within these regions. Currently, we don't have any ETA to share regarding its availability at west US region.
Please refer to the language and voice support documentation: https://learn.microsoft.com/en-us/azure/ai-services/speech-service/language-support?tabs=tts#supported-languages
I hope this helps.
Regards,
Vasavi
