Enum Outcome 

pub enum Outcome {
    Transcript(Transcript),
    NoAudio {
        peak: f32,
        audio: Duration,
    },
}

What a finished transcription produced.

Variants

Transcript(Transcript)

Audio was heard and recognised.

NoAudio

Nothing rose above Config::silence_floor. Distinct from an empty transcript on purpose: a muted input, an unplugged interface, the wrong device and a second process holding the microphone all land here, and a caller that cannot tell them from “you said nothing” has nothing to report.

Fields

peak: f32

Loudest sample seen, in dBFS. The two shapes mean different things and a host should act on them differently.

A finite value below the floor is a quiet room, a distant speaker, or a muted input - ordinary, and retrying may work.

Negative infinity means every sample was exactly zero, which a live microphone does not produce. Measured: five captures of an empty room read -38.2 to -27.5 dBFS and never reached it, while a capture the operating system had refused produced nothing else. So it says something structural sits between the caller and the device - a denied permission, a hardware mute switch, a disconnected interface - rather than that nobody spoke. Which one is a host question; this crate reports the observation.

Also measured: that condition is sticky within a process. A second capture behaved identically with no second prompt, so a host should surface it rather than retry in a loop.

None of that applies to an crate::AudioSource that yielded no samples, which reaches the same value with no device in play at all.

audio: Duration

How much audio was heard, so a caller can say “four seconds of nothing” rather than just “nothing”.
