摘要 |
A noise-contained voice signal is cepstrum-analyzed (2, 528) to determine a peak and a mean-value (3, 4, 538, 548) thereof. When a peak is present, the signal is determined to be a vowel portion, and when a mean-value is large, the signal is determined to be a consonant portion, thereby allowing a voice portion to be accurately determined. Further, utilizing the detected result, a noise is accurately canceled (8, 588). <IMAGE> |
