Speech is the four piper fixtures mavsttd already scores against, so nothing
of the owner's voice is committed. Non-speech is white noise at the same RMS
as the clip beside it.
Silero calls 0 noise frames speech where the energy threshold calls 68 to 99,
and hears all four spoken clips. 509us per 30ms frame, 1.7% of one core on
the slower machine.
White noise is a floor and not a proof. It says nothing about a television,
which is speech, or a fan, which is narrowband.
silero-vad replaces the energy threshold when -vad-model points at it.
Everything after the speech decision is the same state machine: the speech
hold, the silence hold, the length cap and the utterance buffer.
The model window is 512 samples and the capture frame is 480, so silero.go
re-chunks across frames. main.go claimed the two matched, which was true of
silero v4.
Stage two, the wake word, is not here. It needs a Russian keyword model that
does not exist yet.
