The spread of speech is not only depending upon the air, but by means of other medium. This study reports a new speech detecting method by using EMW Radar. However, the combined noise which is added in the detected speech decreased the speech quality to a large extent, since noise is mostly colored and does not affect the speech signal uniformly over the entire spectrum. This study, therefore, propose a multi-band spectral subtraction approach which takes into account the fact that colored noise affects the speech spectrum differently at various frequencies. The results suggest that this method achieves a better reduction of the whole-frequency noise, as well as musical noise, and yields good speech quality.
