alkove.SpeechParams

@dataclass(frozen=True)
class SpeechParams(
    confidence: float = 0.5,
    exit_confidence: float = 0.1,
    start_secs: float = 0.2,
    stop_secs: float = 0.6,
)

Cue’s state machine: speech opens on one frame over confidence, counts after start_secs, closes after stop_secs under exit_confidence.
