- W2384409827 abstract "A kind of single input channel speech enhancement algorithm based on signal subspace is studied for enhancement of speech degraded by colored additi ve noise. An adaptive KLT(Karhunen-Loeve Transform)matrix is applied in the a l gorithm. The approximate model of colored noise is made. In the case of steady n oise, preprocessing VAD (Voice Activity Detection) algorithm is used to obtain noise sample. Then it is used to evaluate the character of noise and to accompl ish denoising processing. Simulation results show that this algorithm demonstrat es better performance than modified spectrum subtraction algorithm both in the e nvironment of white or colored noise." @default.
