* First parameter sourceText: text information to be synthesized. The value can contain a maximum of 500 characters.
* Second parameter indicating the synthesis mode: The format is configA | configB | configC.
* configA：
* MLTtsEngine.QueueAppend：After an audio synthesis task is generated, the audio synthesis task is processed as follows: If playback is going on, the task is added to the queue for execution in sequence; if playback pauses, the playback is resumed and the task is added to the queue for execution in sequence; if there is no playback, the audio synthesis task is executed immediately.
* MLTtsEngine.QueueFlush：The ongoing audio synthesis task and playback are stopped immediately, all audio synthesis tasks in the queue are cleared, and the current audio synthesis task is executed immediately and played.
* configB：
* MLTtsEngine.OpenStream：The synthesized audio data is output through onAudioAvailable.
* configC：
* MLTtsEngine.ExternalPlayback：external playback mode. The player provided by the SDK is shielded. You need to process the audio output by the onAudioAvailable callback API. In this case, the playback-related APIs in the callback APIs become invalid, and only the callback APIs related to audio synthesis can be listened.
