Results of spontaneous speech

In the filled-pause skip experiments, the number of filled-pauses in the vocabulary was 109. The experimental results are shown in Table  4 .

As can be seen, the phone-strings skip method obtains a higher performance than the filled-pauses skip method. In addition, the sentence recognition rate for spontaneous speech is 42.0% as opposed to 25.3% with no such procedure; including the semantically correct sentences, the sentence recognition rate was about 75%. This means that this algorithm is effective in spontaneous speech recognition.
