Answer 1

Hi C-Gregory Padron,

Welcome to Microsoft Q&A Forum, thank you for posting your query here!

It sounds like you’re encountering an issue with the Azure Speech Service Batch Synthesis API. When you specify the output format as audio-24khz-160kbitrate-mono-mp3, but the output is being generated as a WMA file instead, it could be due to a few reasons:

Ensure the output format is correctly specified in the API request. For example:

{
  "description": "Batch synthesis example",
  "inputKind": "PlainText",
  "inputs": [
    {
      "content": "Your text"
    }
  ],
  "properties": {
    "outputFormat": "audio-24khz-160kbitrate-mono-mp3"
  }
}

Use the latest version of the API to avoid any known issues. Refer to the https://learn.microsoft.com/en-us/azure/ai-services/speech-service/batch-synthesis for updates.

Check the logs for any error messages or warnings that might indicate why the output format is not correctly generating.

Hope this helps. Do let us know if you any further queries.
