Diarization not working - AssemblyAI works perfectly

[rlucredio]

Hi, I have this audio (it's fine to share because it's fabricated using AI voices and fake company names). The diarization simply doesn't work, it outputs all utterances as speaker 0. I used the API playground and also my client app. I tried nova-2 and enhanced models, none of them worked.

I tried some other files which did work partially, and I wanted to do a controlled test using 2 ai generated female voices. The voices are similar but not equal. The diarization works out of the box on assembly AI.

If there's a certain combination of model/parameters I should try, please advise. Otherwise I'll spend more time exploring the competitor instead.

I really like Deepgram's speed and features and would like to use it, but if the diarization fails, it's a dealbreaker for me.

I saw some of the discussions, and in one of them, someone suggested using dual channel audio, but that's not an option for me and my client.

Thanks!

• The programming language you are working in (e.g. JavaScript, Python).
  I tested with the API playground direct from the website
• The deepgram product you are using (e.g Speech to Text, Agent API)
  Speech to text
• A request ID that triggered your error or issue.
  No need, if someone tries to transcribe that audio i provided, it'll probably fail. I just need someone with more experience than me to guide me, maybe suggest some sort of parametrization that works
