Add AssemblyAI as a third transcription provider option alongside
OpenAI and Groq. AssemblyAI offers better accuracy for certain
audio types (distant voices, noisy environments) and serves as a
reliable fallback when other providers struggle.
Changes:
- Add AssemblyAITranscriptionProvider class in providers/transcription.py
- Add 'assemblyai' option in base channel's transcribe_audio()
- Per-channel configuration via transcriptionProvider in config
Usage:
Set transcriptionProvider: 'assemblyai' and provide an AssemblyAI
API key via transcriptionApiKey in the channel config.
- Wrap both token estimation calls in try/except to prevent silent failures
from crashing the consolidation cycle
- Add _MAX_CHUNK_MESSAGES = 60 to cap messages per consolidation round,
avoiding oversized chunks being sent to the consolidation LLM
- Improve idle log to include unconsolidated message count for easier debugging
These are purely defensive improvements with no behaviour change for
normal sessions.
The bridge's pn/sender fields don't consistently map to phone/LID
across different versions. Classify by JID suffix instead:
@s.whatsapp.net → phone number
@lid.whatsapp.net → LID (internal WhatsApp identifier)
This ensures allowFrom works reliably with phone numbers regardless
of which field the bridge populates.
