openWakeWord scores one ~80ms frame at a time and the detector fired the instant a SINGLE frame crossed threshold — so a stray phoneme in background conversation could trigger the wake word unintentionally (reported in testing). A real utterance of the phrase holds a high score across several consecutive frames; an ambient blip spikes just one. _OpenWakeWordEngine now requires N consecutive over-threshold frames (wake_word.confirmation_frames, default 3) before firing. The streak resets on any sub-threshold frame and on engine reset() (pause/resume), so a pre-pause frame can't count toward a post-resume fire. confirmation_frames=1 restores the old single-frame behavior; clamped 1..10. Only openWakeWord is affected — sherpa (streaming transducer) and porcupine decode the whole phrase internally and already reject single-frame spikes. - tools/wake_word.py: _confirmation_frames() accessor, streak logic in process()/reset(), config default - hermes_cli/config.py: wake_word.confirmation_frames documented default - tests: 5 new (spike rejected, sustained fires once, =1 legacy behavior, reset clears streak, config clamp) — 58 wake tests green - docs: 'Reducing false triggers on ambient speech' section |
