Research on Speech Signal Analysis and Synthesis for Aural Rehabilitation for the Deaf

A set of computer speech synthesizer and simulator has been developed, based on the speech signal processing, for the deaf children who had accept artificial electronic cochlea cured for aural apperception and rehabilitation. And it could sound the non-speech and speech sounds, including music sounds. The synthesis speech would be used in hearing skill training of aural rehabilitation. The paper will firstly introduce the theory of aural rehabilitation for deaf and speech synthesis technology, and then the demand of speech signal process technology in four stages belonging to the rehabilitation theory. Finally, we address the system architecture of functionality and modularization with more details. We also will introduce the breakthrough and bottleneck of it in the following.
