Author(s): Malczyk Grażyna, Wszołek Wiesław

Stuttering is a disorder of fluency, occurring in both children and adults. It prevents free and smooth transition from one articulation to another, and to maintain an appropriate pace, rhythm and intonation of speech. In natural speech important is the intention of the transmission of information, which determines the rate of speaking and prosody used in a targeted manner. Pathological stuttering is accompanied by physiological symptoms, often combined with co-movements of the body, face, hyperactivity and spasticity. Emotionally it affects communication and social language. Inability to speak liquid leads to tension and stress of speaking. In problems of medical diagnosis, including planning and monitoring the therapy and rehabilitation of voice organs or speech-related organs, it is necessary to evaluate the qualitative features of the acoustic signal of deformed speech. One of the methods of testing which gives opportunities for a proper evaluation of the vocal folds in the process of stuttering, and the diagnosis of these disorders and for monitoring the progress of both, as well as the final effects of stuttering therapy is electroglottographic methods and acoustic spectral analysis of speech. In this paper we present the results of the speech signal stutterers. On the basis of these results, we developed a method of identifying types of stuttering.
