Speech To Text Batch API: Which languages support diarization?

Question

Current when making requests to https://eastus.api.cognitive.microsoft.com/speechtotext/v3.0/transcriptions I get an error saying diarization is not supported for this language. Example request below:
{
"contentUrls": [
"https://contoso.com/mystoragelocation",
"https://contoso.com/myotherstoragelocation"
],
"properties": {
"diarizationEnabled": true,
"wordLevelTimestampsEnabled": true,
"punctuationMode": "DictatedAndAutomatic",
"profanityFilterMode": "Masked"
},
"locale": "he-IL",
"displayName": "Transcription using default model for he-IL"
}

Above example is for a Hebrew mono audio file. The documentation says Hebrew is supported here: https://learn.microsoft.com/en-us/azure/cognitive-services/speech-service/language-support

However requests set up as above return:

{"code":"InvalidPayload","message":"This locale does not support diarization."}}

Is there documentation to say which locales support diarization or is this a bug?

Thanks

Answer 1

@Francis O'Brien Thanks, We have rolled out a fix for this issue to all public regions. Can you please try again.

Answer 2

@Francis O'Brien Thanks for the details. This is indeed a bug, Hebrew (or indeed all locales) should be supported for diarization in most scenarios. We are working on a fix, will update on the same once it's fixed.
