edu.cmu.sphinx.frontend.endpoint.NonSpeechDataFilter

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 {@link SpeechMarker 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.


        input.addAll(createFeatVectors(0.1, sampleRate, 0, 10, 10));


        input.add(new DataEndSignal(0));


        NonSpeechDataFilter nonSpeechDataFilter = ConfigurationManager.getInstance(NonSpeechDataFilter.class);
        List<Data> result = collectOutput(nonSpeechDataFilter);


        Assert.assertTrue(result.size() == 26);


        Assert.assertTrue(result.get(0) instanceof DataStartSignal);
