Simple Model of Speech Communication and its Application to Intelligibility Enhancement

Abstract

We introduce a model of communication that includes noise inherent in the message production process as well as noise inherent in the message interpretation process. The production and interpretation noise processes have a fi xed signal-to-noise ratio. The resulting system is a simple but effective model of human communication. The model naturally leads to a method to enhance the intelligibility of speech rendered in a noisy environ-ment. State- of-the-art experimental results confirm the practical value of the model.
