Voice Focus

Isolate the primary voice and suppress background noise on streaming transcription. Hear the speaker, not the room. Voice Focus isolates the primary voice and suppresses background chatter, keyboard clicks, fan hum, and room echo before the audio reaches the transcription model.

Variants

Pick the variant based on how close the speaker is to the microphone.

Variant	Value	When to use
Near field	`near-field`	Headsets, handsets, and other close-talking microphones.
Far field	`far-field`	Conference rooms, drive-thru speakers, laptop mics, and other distant capture setups.

Tuning parameters

Tune how aggressively each variant suppresses background audio with the following parameter.

Parameter	Type	Default	Description
`voice_focus_threshold`	float	`0.7`	Optional. A float between `0.0` and `1.0` that controls how aggressively background audio is suppressed. Higher values are more aggressive. Defaults to `0.7` for both variants.

Quickstart

Set the voice_focus connection parameter when you open the WebSocket. See Tuning parameters to adjust how aggressively background audio is suppressed.
