In recent years, speech recognition systems have been introduced in a wide variety of environments such as vehicle instrumentation. In such a low SNR environment, a noise signal can be misjudged as speech, dramatically decreasing the recognition rate. Therefore, this study focuses on a recognition system that uses body-conducted signals. Since noise is not introduced within body-conducted signals that are conducted in solids, even within sites such as engine rooms which are low SNR environments, construction of a system with a high recognition rate can be expected.
