The present state of postlaryngectomy speech was investigated in ninty-two patients treated at our department. In eighty-two of these patients, the methods of speech production were by way of T-E shunt, artificial larynx and esophageal speech. Forty-two, thirty-three and seven cases were categorized into these three groups, respectively. Regarding the acceptability of speech as examined by the listening test in each group, speech by T-E shunt was superior. Of the seven patients with esophageal speech six had been the unsuccessful cases of T-E shunt speech who could speak using the shunt for a short period after the operation. The main reason why these patients could obtain esophageal speech spontaneously appears to be based on the fact that they could learn the vibration mechanism for esophageal speech during the period of T-E shunt phonation. In this study, the artificial larynx tended to be used in older patients than those of the other groups. In general, the acceptability of artificial speech appears to deteriorate as the patient becomes older.
