Description
Issue
Current implementation starts audio capture immediately and runs for entire listening session. watchOS devices have limited battery capacity.
Current Problem
- AVAudioEngine is always capturing
- No voice activity detection (VAD)
- No idle timeout
- High battery drain during long conversations
Desired Optimizations
- Implement voice activity detection to only process when user is speaking
- Add configurable idle timeout (e.g., stop listening after X seconds of silence)
- Consider lower sample rates for audio transfer
- Profile battery usage under normal operation
Trade-offs
- More battery life vs. slightly higher latency
- Accuracy of VAD implementation
- User experience during silence (should silence be treated as idle?)

Research direction
Start by locating the AVAudioEngine audio-capture entry point and review how a listening session currently runs. Evaluate voice activity detection, a configurable silence timeout, lower sample rates, and battery profiling; done means reduced battery drain without unacceptable latency or missed speech.
