Abstract:
Objective To investigate the characteristics of laryngeal diadochokinesis(LDDK)in children with functional articulation disorder(FAD)using different corpus.Methods A total of 23 children with FAD and 21 typically developing(TD)children,aged 4-6,from Shanghai's general kindergartens were recruited.Five types of acoustic parameters were collected:average rate and jitter(％)of LDDK(/?a/,/ha/,/??/,/h?/),the diadochoki-nesis rate(/pataka/),the jitter and shimmer of the vowel/a/,maximum phonation time(MPT).Differences across different corpora of the LDDK were analyzed between the two groups.Results ① Between-group compari-son:the rate of/?a/was significantly lower in FAD children than in TD children(P＜0.05).② Different corpora comparison:the LDDK speed of/?a/-/ha/was significantly different for both groups,/?a/-/??/was significantly different in TD children,and/ha/-/h?/was significantly different in FAD children.The LDDK jitter of/ha/-/h?/was significantly different among FAD children.Conclusion The LDDK of children with FAD is weaker than the TD children,and both groups exhibiting varying abilities across different corpora.
