A voice recognition system for speech impaired people

摘要

We show how MATLAB can be used to realize voice recognition for people with cerebral paralysis. The first part of this paper is about what cerebral paralysis is, and its consequences on the way people with this illness talk. We then mention the mathematical background needed to realize this project. We explain the first stage of the system in which some phonemes are recognized. Next, we describe the functioning of the second stage of the project in which words are recognized. Finally, we give some results and we discuss them.
