Abstract

ABSTRACT This article describes a prototype electronic device which is used in the foreign language classroom or laboratory to visually display pedagogical models and student articulations of target language sounds in real-time. The sounds are displayed on the face of an oscilloscope cathode-ray tube (CRT). The students match their production of a target sound to a pedagogical model of that sound which is placed on the CRT face. The pedagogical model and the student articulation are displayed simultaneously as the student produces the sound, thus assuring immediate, concurrent feedback to the student.
