Conversation
Exposes pause and resume controls on the TTSKit AudioOutput so callers can suspend playback (e.g., when the user takes the mic or switches tasks) and resume it without tearing down the audio engine. Mirrors the existing schedule/teardown lifecycle. Tested locally inside an optionOS dictation/TTS pipeline that toggles playback frequently.

Summary
Exposes pause and resume controls on
TTSKit.AudioOutputso callers can suspend playback (e.g., when the user takes the mic or switches tasks) and resume it without tearing down the audio engine. Mirrors the existingscheduleBuffer/ teardown lifecycle.Motivation
We hit this in a dictation/TTS pipeline where a hotkey toggles between recording and speaking; today the only escape is to stop and recreate the engine, which adds latency and drops scheduled buffers.
Changes
pausePlayback()—playerNode.pause()resumePlayback()— restart the engine if it was stopped and resume the playerTesting
Verified locally inside an optionOS dictation/TTS pipeline that toggles playback frequently. Existing teardown path unchanged.
