Abstract
Miniature accelerometers were used to transduce nasal and anterior-neck tissue vibrations of 12 hypernasal and 3 normal children. The accelerometric voltages provided an analog implementation of Horii's (1980) nasal/voice ratio. Simultaneous audio recordings were later evaluated for hypernasality by listeners. Listeners' direct magnitude estimations (DME) of hypernasality were highly correlated with the accelerometric nasal/voice ratio when the stimulus sentences contained obstruents, nonnasal semivowels, and vowels. No correlation existed between DME and accelerometric values when the stimulus sentences contained primarily nasal semivowels and vowels.This publication has 0 references indexed in Scilit:
