I'm trying to use Google's Speech-to-Text v2 API for transcription and speaker diarization.
Per this supported languages page, I should be able to create a Recognizer using the "long" model for the language "en-US" that supports diarization.
And yet every time I try to create such a Recognizer (I've tried using both the UI and the API), I get an error message. In the API it says "Recognizer does not support feature: speaker_diarization" and in the UI it shows the attached message:
Am I missing something here? Why can't speaker diarization be applied?
