When looking at word output data, the two symbols <SIL>
and <s>
sometimes appear. These acoustically represent periods of audio without speech, such as silence or background noise. In the former case (<SIL>
), the recognition process decides this 'silence' probably has no linguistic role. In the latter case (<s>
), the recognition process decides it is more likely to end a chain of words and start anew at this point. This is analogous to starting a new sentence, but is only a weak analogy since the decision is made only with local context words.
