Package edu.cmu.sphinx.frontend.endpoint Description

Provides classes and interfaces used for speech endpointing.

The Sphinx-4 audio endpointer is composed of three data processors that carry out different functions:

SpeechClassifier - classifies chunks of audio into speech and non-speech.

SpeechMarker - marks the audio stream into speech and non-speech regions, by inserting SpeechStartSignals and SpeechEndSignals into the data stream, while giving some 'cushion areas' around these regions.

NonSpeechDataFilter - removes the non-speech regions from the audio.
