Research Abstract

Training of articulation is essential for a good rehabilitation program for laryngectomees. In order to establish an effective rehabilitation program for esophageal speakers, perceptual and physiological studies were conducted and their articulation was analyzed. It was found that vowels were most intelligible, while voiceless plosives and /h/ sound were least intelligible. For fricatives, unskilled esophageal speakers generally showed low intelligibility. In skilled esophageal speakers, most sounds were perceived correctly except for a few mistakes in voiced-voiceless distinction and /h/ sound confusion. /h/ sound was often perceived with omittion, distortion to /ρ/ or addition of /k/. Articulation movements of selected esophageal speakers were analyzed using electropalatography. The examination revealed that all the esophageal speakers showed abnormal linguapalatal contact patterns. One of the esophageal speakers produced a correctly perceived /h/ sound by having bilateral marginal linguapalatal contacts near the back of the tongue, For articulation training of /h/, use of palatal frication seemed adequate, in which the back of the tongue was slightly lowered after having n articulatory posture for /k/ sound.
