My team and I are looking for a service to transcribe audio files with diarization. We started to use the Conversation Transcription speech service but stumbled upon the Speech-to-Text REST API while doing research on how to best architect our product solution and had a few questions.
- Diarization is supported in the Conversation Transcription service with the
DifferentiateGuestSpeakersproperty enabled and in the Speech-to-Text v3.1 REST API with thediarizationEnabledproperty enabled, but these versions are both in preview. Does anyone know when each of these services will no longer be in preview? - The Speech-to-Text REST API appears to be more feature rich. For example, it supports passing a Bob Storage audio file URL opposed to uploading the audio manually, word-level timestamps, and web hook support opposed to polling for updates. The Conversation Transcription service doesn't appear to have any of these features? Does anyone know if the Conversation Transcription services utilizes the Speech-to-Text REST API behind the scenes and if there is a way to utilize these extra features?
Thank you~

Please see this announcement this month. I am not sure if Conversation Transcription will go to GA soon as there is no announcement yet.
Yes, the REST API does support additional features, and this is usually the pattern with azure speech services where SDK support is added later. As far as I am aware the features from REST API cannot be accessed with conversation transcription. Conversation transcription feature is designed for longer conversations with real and asynchronous modes along with single or multi device support which are still under preview.
