Abstract:
Alaryngeal speech(esophageal, neoglottal, shunt, and electrolaryngeal speech) differ from normal laryngeal speech primarily with regard to the sound or source of voicing. Theoretically, esophageal, tracheoesophageal, neoglottal and electrolaryngeal speech have difficulty in accomplishing the voiceless consonants. But perceptual studies often reveal that there is a clear production of voiceless consonants resulting good articulation scores in skilled alaryngeal speakers except electrolaryngeal speech. The purpose of the present study was to relate the three-way distinction of Korean voiceless stops in manner of articulation with normal speakers and skilled alaryngeal speakers in terms of the voicing distinction in consonants. Acoustic analysis were performed to investigate the acoustic characteristics of alaryngeal speech compared to the normal speech with special reference to the voiceless distinction. Electromyographic studies were performed to clarify the adjustment of neck muscle during normal and alaryngeal speech.
