[Abstract] Objective To compare the differences of speech prosodic chunking function between children with normal hearing and hearing impaired children with different types of hearing amplification. Methods A total of 58 preschool normal hearing and hearing-impaired children aged 5.5~6.5 were included, including 30 normal hearing children，10 children with binaural cochlear implant, 8 children with binaural hearing aid, and 10 hearing-impaired children with binaural hearing aid and cochlear implant. The chunking evaluation part of children's speech prosoady function evaluntion tool was used to compare the differences in chunking function performance and the correlution between the input and output dimensions. Results ①The scores of four of parts chunking in hearing-impaired children were significantly lower than those in normal hearing children (P<0.05). ② Among hearing-impnired children with different types of hearing amplication, there was no significant dfference in the scores of two parts of input dimension of prosody chunking (P>0.05). The output dimension scores of prosody form of the cochlear implant group and bimodal group were significantly lower than those in the hearing aid group (P<0.05).The scores of output dimension of prosody function of the cochlear implant group were significantly lower than those in the hearing aid group (P<0.05)，and there was no significant difference in the scores of other groups (P>0. 05). ③There was no correlation between input and output results (P>0.05).Conclusion The input and output of prosodic chunks in hearing-impaired children lag behind those in normal hearing children of the same age. Different hearing amplification methods affect the output of prosodic parts in hearing-impaired children, but have little effect on their input. The overall performance is as follows: cochlear implant group < bimodal group < hearing aid group.The input dimension and output dimension of prosodic chunks do not affect each other.
