Speech processing apparatus |
摘要 |
An input speech signal is processed to compensate for the effects of noise. The input speech signal is divided into a plurality of sequential time frames and a set of spectral parameters are extracted for each time frame. The parameters for each frame are scaled in dependence upon a measure of the signal to noise ratio for the input frame. In this way, the effects of additive noise on the input signal can be reduced.
