- Fix Wyoming satellite crash on wake word: convert macOS .aiff chimes to .wav (Python wave module only reads RIFF format, not AIFF) - Fix OpenClaw HTTP bridge: increase subprocess timeout 30s → 120s, add SO_REUSEADDR - Fix HA conversation component: use HTTP agent (not CLI) since HA runs in Docker on a different machine; update default host to Mac Mini IP, timeout to 120s - Rewrite character manager as Vite+React app with schema validation - Add Wyoming satellite wake word command, ElevenLabs TTS server, wakeword monitor - Add Phase 5 development plan - Update TODO.md: mark voice pipeline and agent tasks complete Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

"""Wake word detection command for Wyoming Satellite.
|
|
|
|
The satellite feeds raw 16kHz 16-bit mono audio via stdin.
|
|
This script reads that audio, runs openWakeWord, and prints
|
|
the wake word name to stdout when detected.
|
|
|
|
Usage (called by wyoming-satellite --wake-command):
|
|
python wakeword_command.py [--wake-word hey_jarvis] [--threshold 0.5]
