| Abstract: | This paper investigates variations of frequencies and amplitudes of F1 and F2 in uttered vowels under noisy conditions, to grasp what strategies speakers use to make uttered speech more intelligible in noisy conditions. Seven types of noise were used for the noisy conditions. Five Japanese vowels (/a/, /e/, /i/, /o/, and /u/) uttered in the noisy conditions by four native Japanese speakers were recorded. Then, frequencies and amplitudes of F1 and F2 were extracted. As the results, it was found that F1 tends to mainly change its frequency and F2 changes its amplitude largely according to sound pressure level of the noises. In detail, these variations depended on the types of the noise. This study also discusses excitation patterns to take accounts of the effects of masking from the noises. These tendencies of F1 and F2 were most likely to be explained by the effects of masking from the noises. |
