Influence of Speech Codec on Speech Enhancement Algorithm in Telecommunication System
YE Lijian · Audio Engineering · 2011
Some speech codec methods and single-channel speech enhancement algorithms are studied.And these two functions are combined to simulate the real telecommunication system.It is concluded that basically in high coding rate,the linear prediction(LP) analysis based speech codec methods do not affect the speech enhancement algorithms,and sometimes reduce the speech distortion owing to the excessive enhancing.So the results of the speech enhancement can be increased.
