Recently we have been experiencing what appears to be a significant regression in speaker diarization quality for prerecorded speech to text, especailly for nova-3.
Here are 3 requests of the same audios from varying sources:
001d5ab5-b650-46a8-8d35-e75bb32ad6e8: Nova-2 in playground. Only one that does diarization well
1e91aeab-93b8-459d-a12b-8b0c2a1ebb92: Nova-3 in the playground. Bad
12baa477-8cdf-4749-8b85-c8906a1d9a4d: Nova-2 via the API. Also bad
Hopefully this is just a temporary bug that can be acknowledged or resolved, as we have had multiple customer complaints of this issue in the last week or so. If not we will likely need to migrate off the platform
