Yes, there are two listeners:

• API 4-14: OnUtteranceCompletedListener
• API 15+: UtteranceProgressListener

I haven’t used the UtteranceProgressListener, but the OnUtteranceCompletedListener is very particular. Here are two tips:

• Set this listener in the onInit() callback, never before.
• You must pass the third parameter params to speak() with a valid KEY_PARAM_UTTERANCE_ID, otherwise this listener is never called.
