抄録

The aim of this study was to acquire an EPG target pattern and quantitative analysis criteria for Japanese sounds used in EPG training.<BR>The subjects were five adults without present or past speech, language, or hearing problems. After the EPG recording, a cumulative template was generated from the maximum contact frame for each sound and the“center of gravity” (COG) value was calculated as a quantitative measure.<BR>The cumulative templates for each sound proved to be a good EPG target pattern for visual feedback training, because they display common interpersonal contact patterns and the area of tolerance. As the COG value represents the relative concentration of electrodes in the anterior-posterior dimension, it is useful for measuring progress from an incorrect posterior placement to a correct anterior placement.
