PURPOSE This study aimed to compare sound production errors arising due to phonological processing impairment with errors arising due to motor speech impairment. METHOD Two speakers with similar clinical profiles who produced similar consonant cluster simplification errors were examined using a repetition task. We compared both overall accuracy and acoustic details of hundreds of productions ...

Previous research using electropalatography (EPG) has shown that a distinctive articulatory characteristic of lingual consonants in the speech of school-age children with articulation/phonological disorders (APD) is a high amount of tongue-palate contact. Consonants produced in this way have been referred to as undifferentiated lingual gestures. This article reviews the EPG literature on undiff...

This paper reviews interactive methods for improving the phonetic competence of subjects in the case of second language learning as well as in the case of speech therapy for subjects suffering from hearing-impairments or articulation disorders. As an example our audiovisual feedback software “SpeechTrainer” for improving the pronunciation quality of Standard German by visually highlighting acou...
