Laryngectomy, as a treatment for malignant laryngeal lesions, requires the patient to seek a substitute method of producing speech. Three types of alaryngeal speech were described: esophageal, Asai, and artificial larynx. One consideration in deciding which mode of speech is best for the patient is how closely each type of alaryngeal speech approximates normal.
This investigation was an objective examination of esophageal, Asai, and artificial larynx speech as compared with normal in males and females.
