| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The extraction method using group delay has been proposed for noisy speech signal in high accuracy. It is difficult to apply to the speech signal of speaker independent condition such as the distinction of sex or age. Even for the same speaker the detection of the event is difficult under the condition of high noisy environment since the phase of the signal is estimated with large variances.In this paper we show that the non-parametric analysis with a kernel is equivalent to the low-pass filtering with a linear phase filter, and a new method is proposed with multiple low-pass filters of the linear phase for the extraction of pitch event as the glottal closure.It is shown that our method is available to extract the pitch event for the speech in the high noisy environment (SN0 $\sim$ 10dB), through the comparison to the conventional method using the group delay. |
