Open volcengine streaming ASR's `enable_speaker_info` flag so each returned utterance carries a speaker label. Then in the result assembly, group utterances by speaker, pick the one with the longest total speaking time as the "primary speaker", and only concatenate their text — dropping utterances from other speakers (e.g. a colleague interjecting while you dictate). This is a heuristic quick-win for the "only transcribe my voice" request; it does not yet do enrolled voiceprint verification. If no speaker labels are present, behavior is unchanged (all utterances concatenated).
