Articulation Characteristics And Speech Training Of Consonants In Post School-aged Patients With Functional Articulation Disorders

ObjectiveTo discuss the phonetic characteristics of abnormal consonants in post school-aged patients with functional articulation disorders and explore the training plan and methods in order to improve the phonetic intelligibility of patients and provide reference for clinical speech treatment.Methods300 post school-aged patients with functional articulation disorders were selected as research objectives.They all came from speech therapeutic room in the First Affiliated Hospital of Zhengzhou University during October 2015 to December 2016,male 228 cases,female 72 cases,aging from7 to 26.The ratio of male to female was 3.2:1.300 patients were given speech assessment by using CSL according to speech intelligibility test table of Hua xi oral hospital,for analyzing the articulation characteristics of abnormal consonants.80 patients who met the criteria were recorded in according to the Chinese speech intelligibility test table before and after speech training respectively and the speech intelligibility was calculated for the evaluation of speech training effect.Statistical analysis was performed by SPSS17.0 statistical software.The type of experimental design of study one was descriptive research,and that of study two was self-paired design and paired t-test was performed for the speech training effect,?=0.05.ResultsThere were 166 cases of school-aged children,72 cases of adolescents and 62 cases of adults among the 300 patients with FAD,the proportion of which among all the subjects were 55.3%,24.0% and 20.7% respectively.The ratio of the three groups was 2.7:1.2:1.The abnormal consonants lay in blade-palatal,blade-alveolar and dental.The error ratio of blade-palatal was the highest,and that of bilabial was the lowest in each group.The error types of articulation were distortion,substitution,omission and lateral misarticulation and the error rate of the first two decreased and that of the latter two increased with the increase of age.The highest ratio of substitution and omission lay in school-age group,which were 90.4%(150/166)and 58.4%(97/166)respectively.The lowest ratio of distortion and lateral misarticulation lay in adult group,which were 56.5%(35/62)and 40.3%(25/62)respectively.The error form of articulation disorders with highest error rate were omission of /l/ and distortion of blade-palatal among three groups,the proportion of which were 45.2%(75/166),48.6%(35/72)and 35.5%(22/62)respectively.The speech intelligibility of 80 patients with FAD was improved to(90.69±3.14)after speech training from(48.69±11.66)before speech treatment was established.The speech intelligibility was significantly improved through speech training and the difference was statistically significant(t=29.489,P<0.001).The speech intelligibility of each group was also obviously improved(t=17.786,17.692,15.216,P<0.001).But the difference among groups was not statistically significant(H=0.380,P=0.827).The difference of the time needed to master the error consonant was statistically significant(H=43.897,P<0.001)? ConclusionThe articulation characteristics of consonants in post school-aged patients with FAD mainly manifest apical articulation disorders.The error types of articulation are distortion,substitution,omission and lateral misarticulation.Specific performance lies in patients of different developmental stages.The older the patients are,the greater difficulty of speech treatment.Targeted speech training methods are suggested to be established according to the personalized phonetic characteristics of post school-aged patients of different developmental stages.
