| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper proposes a signal subspace approach for speech enhancement in colored noise. The handling of colored noises is an important issue for speech processing in real environment. The proposed approach employs two schemes to handle the colored noise case. One is subband processing. The subband processing has the effect that the noise within every band can be more accurately assumed to be white. In addition, the subband processing provides the effect to reduce the computational load. The other is prewhitening processing. The prewhitening processing is accomplished using low-order linear prediction filters of the subband noise signals. The proposed approach and other conventional subspace approaches were compared in enhancing speech signals degraded by several kinds of colored noises. |
