• Remove bracket cues from TTS-aligned tokens, keeping the survivors' timings.

    useTtsAlignedTranscript makes the provider's alignment of the text it was sent the transcript, and that text is post-convertMarkup, so it carries native [laugh]/[speak calmly] cues as words the agent never spoke. Every bracket span goes: the provider reads them all as cues, so none is ever audio, and markdown links are already gone (filterMarkdown runs on TTS input by default).

    Alignment arrives in messages finer-grained than a cue — often one word at a time — so held carries the tail of an unclosed span across calls; pass the same array every time and call once more with final: true at end of stream to release it.

    Parameters

    Returns TimedString[]
