Abstract:
As for enhancing the speech recognition rate of the skinhearing system,we propose a multiband spectral subtraction based speech enhancement algorithm. Colourednoise can depress the speech quality sharply in the experimental test of the skinhearing system, we embed the multiband spectral subtraction based speech enhancement algorithm into the skinhearing system. The multiband spectral subtraction based speech enhancement algorithm divides the whole frequency bands to multi bands that each band can be processed by its features, and we emulate the algorithm by using Matlab and realize it by DSP hardware, which outputs the processed speech to the skinhearing system. The experimental results prove that it can enhance the reliability and practicality of the skinhearing system.
Key words: skinhearing;spectral subtraction;speech enhancement;multichannel;DSP
