Diarization Inconsistencies with Nova-2 and Limited Language Support in Other Models

[rizz-official]

The diarization feature in Deepgram has the following issues:

Inconsistent Diarization with Nova-2:

Speaker detection is unreliable when using the nova-2 model with diarization enabled for supported languages.
Sometimes speakers are detected, but the diarization accuracy is low.
Diarization Limitations in Other Models:

Models like nova-phonecall and nova-medical do not support diarization for languages other than English.
Attempting diarization with non-English languages on these models results in a 400 Bad Request error.
