Abstract: Objective To discuss the clinical features and speech training of bilabial consonant articulation disorders. Methods 92 patients with functional articulation disorders (FAD) and 85 patients repaired cleft palate were studied. Then 20 patients with bilabial consonant articulation disorders were selected respectively from two types of patients for speech training. Results FAD patients who replaced /p/with /b/ accounted for 78.8% in patients with bilabial consonant articulation disorders, and the patients repaired cleft palate dropped or replaced /b/ accounted for 30.2% and 60.4% respectively. Both types of the patients with bilabial consonant articulation disorders made less mistakes after speech training (P<0.001). Conclusion Bilabial consonant articulation disorders mainly show unaspirated about /p/ in FAD patients, and show dropping and replacement about /b/ in the patients repaired cleft palate. The speech training is significantly effective.
