Objective To investigate the clinical characteristics of 21 syllable-initial consonants errors in the children of functional articulation disorders(FAD), and provide reference for clinical treatment. Methods Specific test was carried in 71 children with FAD.The phonological samples were collected and analyzed. Results 1)Consonant sequence according to the error frequency by descending order was/ch/、/sh/、/k/、/zh/、/z/、/g/、/r/、/c/、/s/、/t/、/x/、/h/、/f/、/q/、/p/、/n/、/l/、/d/、/j/、/b/、/m/.2)Substitution was the main error types of 21 syllable-initial consonants, omission and distortion followed.3)Classified by place and manner of articulation, the main error type wereblade-alveolar, velars et al.
