Jintao Wu · Jisuanji fangzhen · 2012
Aiming at the characteristics that the parameter codes algorithm can not extract parameters accurately in case that noises in the speech correspondence are inescapability and can not be able to filter entirely,the paper proposed an advanced multi-band excitation speech encode algorithm based on the speech enhancement technique.Then the paper described the priniple of speech enhancement algorithm succinctly and introduce the extracting method of the algorithm parameter in detail.The chart of the simulating experiment displays that the synthetic voice disposed by the speech enhancement technique is obviously better than the synthetic voice which is no disposal,which indicates that the encode algorithm based on spech enhancement technique in this paper can eliminate noise so efficiently and extract speech parameter so accurately that the result of synthetic voice is better.
