Computer program for visual diagnosis of the speech disorders

Abstract

The diagnosis of speech disorders requires not only audio but also visual analysis. The speaker often performs many articulation moves, e.g.: a movement of mouth without emitting sound. Therefore a computer program was developed for simultaneous analysis of several elements in conjunction with the digital recording of a person's speaking face. These elements are: sound, a spectrogram picture and an oscillogram. The program can read audiovisual recordings and allows for multiple playing with a selected pace. What follows from the previous work with the program, it gives much important information about the kind and the essentiality of the speech disorders.
