How many speakers limites in one training?

Question

Hi,

I am working on a project for people meeting note generation. I want to know how many speakers can be recognized in Speech Service? Any limitation?

Hello @rankin

Thanks for reaching out to us in Microsoft Q&A platform - I think you are referring to Conversation transcription that provides real-time or asynchronous transcription of any conversation. This feature, which is currently in preview, combines speech recognition, speaker identification, and sentence attribution to determine who said what, and when, in a conversation.

https://learn.microsoft.com/en-us/azure/cognitive-services/speech-service/conversation-transcription

It does support Multi-speaker diarization: Determine who said what by synthesizing the audio stream with each speaker identifier. There is no limit for number of speakers. Although conversation transcription doesn't put a limit on the number of speakers in the room, it's optimized for 2-10 speakers per session.

If you are referring other feature of Speech Service which you want to recognize the speakers, the limit is the same - 2 to 10 will be in good accuracy range.

I hope this helps.

Regard,
Yutong
