Hidden Markov Models in Speech Recognition

Abstract

Voice control is one of the perspective areas of interdisciplinary field called Human Machine Interface (HMI). By the voice control of machines, we usually deal with the recognition of commands from previously defined set. There are many different techniques of speech recognition. At presence, Hidden Markov Models (HMM) are among the most frequently used. This article includes basic terms as well as required mathematical apparatus from stated area.
