| Outline of Final Research Achievements |
The results of acoustic analysis and the psychoacoustic evaluation of hoarse voice showed that the main clue of psychoacoustic evaluation of hoarse voice were acoustic parameters PPQ, JP, HNR and NNEa. A beginner of psychoacoustic evaluation of hoarse voice was mainly using PPQ and JP for the clue of evaluation. As compared with this, an expert of psychoacoustic evaluation of hoarse voice was considered to use and evaluate other acoustic parameters (HNR, NNEa) at the clue of evaluation in addition to PPQ and JP. On the other hand, it was thought that the acoustical clue of the evaluation of lateral articulation voice were an intensity difference of first and second formant frequency, a Q value which indicate sharpness of second formant and a noise level of a consonant.
Furthermore, the psychoacoustic evaluation training and learning program which based on this study were developed, and a validity of the program was affirmed.
