AN ELECTROPALATOGRAPHIC ANALYSIS OF STUTTERERS SPEECH

Electropalatography (EPG) was used to investigate tongue-palate contac ts from three adult stutterers during fluent and dysfluent speech and the results compared with normative data. Recordings were made of 22 r ead sentences, a reading passage and a conversational sample. The resu lts showed that the lingual/palatal contacts of some phonemes during p eriods of stutterers' fluent speech consistently differed from that of the non-stutterers. Furthermore, stutterers produced greater intrasub ject articulatory variability. Finally, during successive repetitions, the EPG patterns often became less similar to the target (or 'normal' ) configuration.
