| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | A noise reduction system based on an adaptive line enhancer (ALE) and a noise estimation filter (NEF) has been proposed to reduce both wideband and sinusoidal noise in noisy speech. In the case of using a fixed step size with which tap coefficients of the adaptive filter is updated, it is difficult to reduce background noise while maintaining the high quality of enhanced speech. Therefore, a variable step size is introduced to the NEF. In a speech section, a small step size is used so as not to estimate speech. On the other hand, a large step size is used to track background noise in a non-speech section. | |
