The aim of this study was to investigate the effectiveness of articulation training for specific phonemes on the production of phonemes in conversational language samples, the 108 Single Word Articulation Test (Paatsch, 1997), and the Phonetic Level Evaluation (Ling, 1976). Speech production skills of 12 hearing-impaired children were assessed using these evaluation tools pre- and posttraining. A total of six phonemes were selected for each child to be trained during 15-to 20-minute daily sessions throughout an 8-week speech production program. Three phonemes, with a particularly high error rate, were trained at a phonetic level (category 1) while three phonemes, with an intermediate error rate of 40% to 70%, were trained at a phonological level (category 2). Results showed improvements in the percentage of correctly articulated category 1 phonemes and category 2 phonemes. The improvements for …
