Hello @Dailylive , Thanks for using Microsoft Q&A Platform.
As per the error message looks like you are using a standard voice. If you are looking to use those voices, your speech resource must have created prior to September 1, 2021.
We are retiring the standard voices from September 1, 2021 through August 31, 2024. If you used a standard voice with your Speech resource that was created prior to September 1, 2021 then you can continue to do so until August 31, 2024. All other Speech resources can only use prebuilt neural voices. You can choose from the supported neural voice names. After August 31, 2024 the standard voices won't be supported with any Speech resource. The pricing for prebuilt standard voice is different from prebuilt neural voice. Go to the pricing page and check the pricing details in the collapsable "Deprecated" section. Prebuilt standard voice (retired) is referred as Standard.
Please refer to this documentation for more details: https://learn.microsoft.com/en-us/azure/ai-services/speech-service/how-to-migrate-to-prebuilt-neural-voice
If you still face issue, please share more information.
I hope this helps.
Regards,
Vasavi
