Most-recent materialized threshold map (after any cloud→local fallback rescale or server-default adoption).
Threshold above which a pause is a backchannel opportunity, or undefined
when backchannel is disabled (server sent none, or the local mini model).
Optional connThreshold below which the detector treats the prediction as "unlikely
to be end-of-turn". Returns undefined when the language isn't covered.
Replace the user threshold override at runtime. The shared
ThresholdOptions re-resolves against the current (server or shipped)
defaults, so an active stream picks it up immediately.
Optional backchannelOptional unlikely
Current model name. Starts at the construction-time selection and flips to
'turn-detector-v1-mini'after a cloud→local fallback: the detector and its (single) active stream share one mutableThresholdOptions, and the stream writes the swap back here so EOU metrics andaudio_recognitionsee a consistent view. The fallback is one-way and sticky.
