Abstract
|
|
|
Theoretically, alaryngeal speakers have difficulty in accomplishing the production of voiceless consonants. However, the perceptual studies often reveal a clean production of voiceless consonants giving good articulation scores in skilled alaryngeal speakers. The purpose of the present study was to clarify the production of voiceless stops in mode of articulation to normal speakers and skilled alaryngeal speakers. The acoustic characteristics of alaryngeal speech compared to the normal speech were investigated with special reference to the voiceless stop consonants. The surface electromyography from neck is used to monitor pharyngeal activity during speech. The general result is that esophageal, shunt and neoglottal speakers realize the distinctions between the threetypes of [p] in a manner parallel to normals, whereas those using an electric voice generaor do not.
Keywords : Voiceless stops, Alaryngeal speakers, Acoustic, Electromyographic.
