摘　　要：目的 探讨不同语言线索条件下,语速变化对学龄前人工耳蜗植入(CI)儿童言语识别的影响,并为其术后言语康复训练提供科学依据。方法 纳入符合条件的学龄前CI儿童16名,对其在不同语言线索(视听结合-AV、仅视觉-VO、仅听觉-AO)及不同语速(慢速、常速、快速)条件下进行开放式言语识别能力测试,共设立9种评估条件。使用SPSS 26.0软件进行数据统计分析。结果 语言线索与语速对CI儿童言语识别能力的影响存在显著交互效应(F=3.517,P=0.012,偏η2=0.190),进一步分析结果发现:在所有语言线索条件下,相比于常速和慢速,快语速下的识别得分均显著下降(P<0.05);当存在听觉语言线索时,即在AV(P=0.459)与AO(P=0.307)条件时,慢速与常速之间的识别得分无显著差异,而VO条件下,慢速下得分显著高于常速(P=0.028)。在所有语速条件下,VO的言语表现均低于AV(P<0.05)及AO言语表现(P<0.05);而当语速减慢时,AV的的识别得分显著优于仅听觉AO(P=0.006),余语速条件下不同语言线索言语识别得分无显著差异(所有P<0.05)。结论 语言线索和语速显著影响CI儿童言语感知能力,并且两者之间存在交互作用,而不是独立影响。综合视听线索可促进CI儿童的言语康复,其中听觉线索的作用尤为关键。在听觉线索充足时,语速的影响被减弱;当听觉线索不足时,语速变快则对言语识别产生更大的负面影响。因此,在CI儿童术后康复训练及效果评估时应充分考虑语言线索和语速的影响。Objective To investigate the influence of speech rate variations on speech recognition of preschool children with cochlear implant(CI) under different verbal cue conditions,providing a scientific basis for their postoperative speech rehabilitation.Methods Sixteen eligible preschools with CI were enrolled to undergo open-set speech recognition tests under different verbal cue(audiovisual-AV,vision-only-VO,and auditory-only-AO) and speech rates(slow,normal,fast),resulting in nine assessment conditions.SPSS 26.0 software was used for statistical analysis.Results There were statistically significant interaction effects between verbal cues and speech rate(F=3.517,P=0.012,partial η2=0.190).Further analysis revealed that:in conditions with linguistic cues AV,AO,and VO,the recognition scores at fast speech rate decreased significantly compared with normal speech rate(P<0.05).When auditory cues were present,as in AV(P=0.459) and AO(P=0.307),the mean scores between slow and normal speech rate were not significantly different,while in VO condition,slow speech rate was significantly higher than normal speech rate(P=0.028).Under the three speed conditions,the speech performance of VO was lower than that of AV(P<0.05) and AO(P<0.05).At fast(P=0.743) and normal(P=0.113) speech rates,there was no significant difference in scores between the AV and the AO;However,when the speech rate was reduced to slow,the recognition score of AV was significantly better than that of the AO(P=0.006).Conclusion Language cues and speech rate significantly affect speech perception in children with CI,and there is an interaction between the two,but not an independent influence.Integrating audiovisual cues can facilitate speech recognition in CI children,and the role of auditory cues is particularly critical.The impact of speech rate is diminished when auditory cues are sufficient,conversely,an increase in speech rate can exacerbate the negative influence on speech recognition when auditory cues are lacking.Therefore,the influence of language cues a
