| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The actual speech signal fluctuates within a finite range and the observed data sometimes display amplitude saturation owing to the existence of a definite dynamic range. On the other hand, several noise removal methods for the speech signal have been proposed up to now. In this study, a signal processing method to remove the noise for actual speech signal is proposed in a form appropriate for the finite amplitude range of the measured data. More specifically, by introducing a statistical orthogonal expansion expression of the probability distribution based on a Beta distribution defined within a finite fluctuation range of speech signal, a new type of noise removal method is proposed. Furthermore, the effectiveness of the proposed method is confirmed experimentally by applying it to actual speech signals contaminated by noise. | |
