Albert	0b632a31eb	fix: Implement working voice transcription with Deepgram API key ... After testing, discovered that temporary tokens from grantToken() fail with WebSocket connections. Switched to using API key directly, which is the standard approach for client-side Deepgram WebSocket connections. Changes: - Simplified voice-token route to return API key directly - Added comprehensive logging to MicrophoneRecorder for debugging - Documented security considerations and mitigation strategies - Verified working end-to-end voice transcription This matches Deepgram's official Next.js starter pattern and is the recommended approach for client-side real-time transcription. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-11-09 06:13:45 +00:00
