Add audio_url support to /transcribe endpoint for remote audio files from frontend

[sohampirale]

• The /transcribe endpoint currently only accepts local file_path parameters, but the frontend needs to send audio URLs from Firebase storage. We need to enhance the endpoint to support both local file paths and remote URLs for audio transcription.

Currently, the frontend sends requests to /transcription/transcribe with an audio_url parameter, but the backend only accepts file_path. This prevents the frontend from using audio files stored remotely in Firebase.

Screenshots

• Current expected body schema

• Filepath : app/routes/transcript_routes.py

transcription_transcribe_request_model = api.model('TranscriptionTranscribeRequestModel', {
      'file_path': fields.String(required=True, description='Path of the audio file.', example='audio.mp3')
})

Proposed Solution

The solution should:

• Allow the /transcribe endpoint to accept both file_path and audio_url parameters
• Implement URL handling with the AudioService for remote audio files
• Add validation to ensure either file_path or audio_url is provided (but not both)
• Maintain backward compatibility with existing file_path functionality
