AssemblyAI API Error

Issue: AssemblyAI API Transcription Failure
Root Cause: The transcription request is using a deprecated parameter. The error message indicates that the speech_model field is no longer supported by the AssemblyAI API.

Technical Details:

• Service: AssemblyAI

• Error Message: speech_model is deprecated. Use "speech_models" instead. (Note: The error text in the screenshot contains a likely typo, but the intent is a field name change).

• Documentation Reference: https://www.assemblyai.com/docs/pre-recorded-audio/select-the-speech-model

Required Action:
Update the API request payload to replace the deprecated speech_model key with the current supported parameter (likely speech_model with updated values like best or nano, or the plural speech_models if using multiple models). The developer should verify the exact key name and valid string values against the linked documentation.
