Aviation is one of the critical modes of our national transportation system. As such, it is essential that new technologies be continually developed to ensure that a safe mode of transportation becomes even safer in the future. The NASA Aviation Safety Program (AvSP) is managing the development of new technologies and interventions aimed at reducing the fatal aviation accident rate by a factor ...

Language modeling is a crucial component in natural language continuous speech recognition, due to the difficulty involved by continuous speech [1], [2]. Language modeling attempts to capture regularities in natural language for the purpose of improving the recognition performance. Many studies have shown that the word error rate of automatic speech recognition (ASR) systems decreases significa...

With the more widespread use of lower bit rate speech coders, the evaluation of speaker recognizability becomes a major issue to be addressed as well as the evaluation of overall voice quality. Furthermore, subjective quality evaluation of speech coders may produce di erent results depending on the voice character of the speakers used in the evaluation process. It follows naturally that methods...
