抜粋

This paper presents a digital filtering algorithm that clarifies dysphonic speech with the speaker's individuality preserved. The study deals with the clarification of esophageal speech and the speech of patients with cerebral palsy. The filtering ability is evaluated by listening experiments. Over 20,000 patients currently suffer from laryngeal cancer in Japan, and the only treatment for the terminal symptoms requires the removal of the larynx, including vocal cords. The authors are developing a clarification filtering algorithm of esophageal speech, and the primal algorithm of software clarification and its effectiveness was reported in the previous ICDVRAT. Several algorithms for the clarification have been newly developed and implemented and are being evaluated by questionnaires. The algorithms were extended and applied for the clarification of the speech by the patients of cerebral palsy.
