| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Under the noise environment, we speak loud voice unconsciously because the auditory feedback is not enough by noise. In this case, the Lombard effect occurs by loud voice, spectrum is distorted, and shifting local peaks of spectral envelopes is known. As a result, the recognition rate decreases compared with usual voice. In this paper, the method for improvement of the recognition rate is shown in case that the speakers utter the loud voice. We correct the transition of formant of loud voice using frequency warping method. In addition, we emphasize a formant using emphasizing the local peaks of spectrum. |
