方法54名听力正常儿童包括12名西班牙语-英语双语儿童(M=6；0[岁；月])、12名单语英语听力障碍儿童(M=6；1)、20名双语听力障碍儿童(M=6；5)和10名单语英语听力正常儿童(NH)。图片诱导靶向/S/、/tʃ/和/ʃ/。结果两组受试者在3个声学参数中均能分辨出目标声音。在摩擦持续时间和上升时间方面，双语顺位儿童的西班牙语发音与非母语儿童的西班牙语发音不同。双语和单语CI使用者的英语沟通持续时间模式也不同。与CI儿童相比，NH儿童的质心频率是一个更强的位置线索。结论摩擦和塞音的产生模式表现出双语和信号减弱的效应，产生了双语和单语CI使用者独特的模式。
PurposeThis study investigates the production of voiceless alveolar and postalveolar fricatives and affricates by bilingual and monolingual children with hearing loss who use cochlear implants (CIs) and their peers with normal hearing (NH).MethodFifty-four children participated in our study, including 12 Spanish–English bilingual CI users (M= 6;0 [years;months]), 12 monolingual English-speaking children with CIs (M= 6;1), 20 bilingual children with NH (M= 6;5), and 10 monolingual English-speaking children with NH (M= 5;10). Picture elicitation targeting /s/, /tʃ/, and /ʃ/ was administered. Repeated-measures analyses of variance comparing group means for frication duration, rise time, and centroid frequency were conducted for the effects of CI use and bilingualism.ResultsAll groups distinguished the target sounds in the 3 acoustic parameters examined. Regarding frication duration and rise time, the Spanish productions of bilingual children with CIs differed from their bilingual peers with NH. English frication duration patterns for bilingual versus monolingual CI users also differed. Centroid frequency was a stronger place cue for children with NH than for children with CIs.ConclusionPatterns of fricative and affricate production display effects of bilingualism and diminished signal, yielding unique patterns for bilingual and monolingual CI users.
