Comparison of Acoustic Parameters and Perception of Breathness and Nasality and Their Relation to the Pleasantness of Voice

This research aimed at establishing acoustic characteristics of breathy and nasal voices, in order to use these results in voice aes-thetics of voice professionals. Thirty-six trained judges evaluated degree of breathness, nasality and pleasantness of 104 male and 103 female voices. The voices were evaluated in a normal and in a rever-sed sound-order. These results were put into correlation with acous-tic variables of LTAS and then ANOVA procedure was applied and Scheo-ffe test for establishment of the significence differences. It was established that female voices showing the highest degree of breat-hness had statistically significantly 3.5 to5 kHz and in the range from 5 to 10 kHz ; and male voices had lower energy from 2.5 to 3.5 kHz and had higher energy from 5 - 10 kHz in relation to non-breathy voices. Female voices showing the highest degree of nasality have significantly higher energy from 70 to 400 Hz in a reversed sound or-der evaluation and lower energy in the part of spectrum from 1 to 1.2 kHz and from 2.5 to 5 kHz (2.5 to 3 and 3.5 to 5 kHz) in a normal so-und order, and male voices have lower energy from 330 to 550 Hz and higher energy from 850 Hz to 3 kHz in a normal sound order (significantly higher energy from 0.55 to 1 kHz, in a reversed sound order evaluation) in relation to the non-nasal voices. Also, male na-sal voices have non significantly lower energy from 3 to 10 kHz. It can also be said that nasality, more than breathness is connected with unpleasant voices.
