how to use cmu sphinx segmenter class - cmusphinx

Question

I am trying to use segmenter class in cmu sphinx to get the time when a speech is recognized in a sound file. However, I can't seem to get it to compile and run. Is there something that needs to be configured first in order to use segmenter? Sorry I am new to CMU Sphinx.
------------------------------------Here is the code for the segmenter------------------------------

wavWriter.setOutFilePattern(outputFile);
frontend.initialize();

} while (data != null);
}

In common case see the TranscriberDemo. If you need to time-align long audio, see the AlignerDemo.
