Applications of Voice/Sound Sensors in Railroad Field

Abstract

This paper presents automatic speech recognition as one of the most advanced examples in the senso-informatics arena and a new method of statistical multidimensional scaling technique which enables projection of multidimensional statistical models onto visible two-dimensional space. Finally, it is discussed that a speech and sound sensors based on both the speech recognition technologies and the statistical multidimensional scaling method are applicable as practical applications in a railroad field.
