Abstract: Objective To explore the phonological characteristics and rehabilitation training of abnormal velar in patientswith functional articulation disorders (FAD). Methods Eighty-seven patients with FAD were observed of the phonologicalcharacteristics of velar. Seventy-two patients with abnormal velar accepted speech training. The correlation and simple linearregression analysis were carried out on abnormal velar articulation and age. Results The articulation disorder of /g/ mainlyshowed replacement by /d/, /b/ or omission. /k/ mainly showed replacement by /d/, /t/, /g/, /p/, /b/. /h/ mainly showed replacementby /g/, /f/, /p/, /b/ or omission. The common erroneous articulation forms of /g/, /k/, /h/ were fronting of tongue andreplacement by bilabial consonants. When velar combined with vowels contained /a/ and /e/, the main error was fronting oftongue. When velar combined with vowels contained /u/, the errors trended to be replacement by bilabial consonants. After3 to 10 times of speech training, the number of erroneous words decreased to (6.24±2.61) from (40.28±6.08) before the speechtraining was established, the difference was statistically significant (Z=-7.379, P=0.000). The number of erroneous wordswas negatively correlated with age (r=-0.691, P=0.000). The result of simple linear regression analysis showed that the determinationcoefficient was 0.472. Conclusion The articulation disorder of velar mainly shows replacement, varies with the vowels. The targeted rehabilitation training hereby establishedis significantly effective. Age plays an important rolein the outcome of velar.
