• ⚠️ TTSService.add_word_timestamps() no longer supports the "Reset" and "TTSStoppedFrame" sentinel strings. If you have a custom TTS service that called await self.add_word_timestamps([("Reset", 0)]) or await self.add_word_timestamps([("TTSStoppedFrame", 0), ("Reset", 0)], ctx_id), replace them with await self.append_to_audio_context(ctx_id, TTSStoppedFrame(context_id=ctx_id)) and let _handle_audio_context manage the word-timestamp reset automatically.
