Some destinations offer a built-in queuing system. When a new message is injected and there is an ongoing message playing, then the new message is put into a queue. After the ongoing message finishes playing, the next message in the queue automatically starts to play.
참고
The following code example uses the Queued Local Playback destination, but you can inject all text-to-speech (TTS) messages into any of the TTS destinations.
vx_tts_utterance_id firstUtteranceId;vx_tts_speak(managerId, voiceId, "Example message, this is great!", tts_dest_queued_local_playback, &firstUtteranceId);// Immediately injected and returns tts_status_successvx_tts_utterance_id secondUtteranceId;vx_tts_speak(managerId, voiceId, "Really amazing.", tts_dest_queued_local_playback, &secondUtteranceId);// Put in a queue and returns tts_status_input_text_was_enqueued. After the first message finishes playback, this message will start.
A queue is shared between and . has its own queue.
