public class SpeechInterrupter
extends BaseDataProcessor

SpeechInterrupter allows insertion of SpeechEndSignal and SpeechStartSignal packets into an audio stream in order to force the interruption of an on-going recognition. This allows the recognition grammar to be switched asynchronously.

The SpeechInterrupter also runs a thread to pull data eagerly through the frontend; this ensures that interruption events occur at the right point in the timeline, as well as helping upstream LevelMonitors, etc, remain in real time (even if the recognizer is running behind).
