# Audio Output Control Calls

An application can control speech output using the following calls:

· TextToSpeechPause

· TextToSpeechResume

· TextToSpeechReset

These calls pause the audio output, resume output after pausing, and reset the text-to-speech system.

A reset discards all queued text and stops and discards all queued audio. If the application has called TextToSpeechOpenInMemory to store speech samples in memory, a reset causes all buffers to be returned to the application.
