All Implemented Interfaces:

DataProcessor, Configurable

public class NonSpeechDataFilter
extends BaseDataProcessor

Given a sequence of Data, filters out the non-speech regions. The sequence of Data should have the speech and non-speech regions marked out by the SpeechStartSignal and SpeechEndSignal, using the SpeechMarker.

Only one speech region

In the first case, the data stream has only one speech region:

Figure 1: A data stream with only one speech region.

After filtering, the non-speech regions are removed, and becomes:

Figure 2: A data stream with only on speech region after filtering.
