A user tried to use transcript.word_search(["price", "product"]) as a keyword trigger to stop a live transcriber, and it did nothing. Maintainer ccampbell-aai clarified that word_search is a prerecorded-only feature: it runs against a completed transcript via the word-search endpoint and has no role in a live session. For the actual goal, stopping when the speaker pauses, the streaming client already provides it: every Turn event carries end_of_turn, which is True when the model decides the speaker finished.
