[Perceptual, acoustical and aerodynamic study of whispering].
Perceptual study: Sixty-seven Japanese monosyllables were whispered by 12 normal speakers and tape-recorded. Listening tests by 24 normal listeners revealed that vowels, semivowels, nasals and fricatives were identified with excellent scores. Although voiced stop consonants were frequently judged as corresponding voiceless consonants, the difference in scores between the two groups was not statistically significant. Acoustical study: The acoustical features of the samples uttered by the subjects who were skilled in whispering showed that first-formant transition plays an important role in discrimination between voiced and voiceless stop consonants. Aerodynamic study: In the subjects who were skilled in whispering, intraoral air pressure was significantly higher in voiceless stop consonants than in corresponding voiced consonants. As a result, it was suggested that the articulation score of whispering would be improved when uttered under acoustical and/or aerodynamic monitoring.
