Abstract:
Objective To study the phonetic characteristics of patients with abnormal plosive consonant of functional articulation disorders (FAD) and the possible treatment approaches.Methods A total of patients of 4~26 years old with abnormal plosive consonant of FAD received speech assessment and the phonetic characteristics.Incorrect articulation patterns and forms of plosive consonant /b/,/p/,/d/,/t/,/g/ and /k/ were analysed.The targeted speech treatment was established to correct the erroneous places and types of pronunciation.Results The error rate of /t/ (82/87)was the highest,followed by /k/(77/87),/d/(67/87),/g/(60/87),/p/(59/87) and /b/(3/87) which was the lowest.The error rate of fricative was 65.52% as the highest among all the erroneous patterns,followed by unaspiration(63.22%),forward movement of the tongue(54.02%),distortion(33.33%),bilabial(32.18%),and backward movement of the tongue(18.39%).Seventy-one cases were completely cured,and 16 cases partially cured after 2 to 10 times of treatment.The number of incorrect words of plosives decreased to 4.03±2.71 after the speech therapy from 67.97±18.56 prior to that.The differences were statistically significant (t =34.301,P<0.001).Conclusion The articulation errors of plosives occur mainly on /t/,/k/,/d/,/g/and /p/,/b/.The incorrect types of pronunciation are fricatives,unaspiration,distortion and omission.The incorrect places of articulation are forward movement of the tongue,bilabial and backward movement of the tongue.The targeted speech therapy established according to the erroneous places and types of articulation is significantly effective.
