Assessing the role of experience on infants' speech discrimination.

Abstract: Several studies have investigated the effect of a particular linguistic environment on infants' discrimination of voicing for stop consonants. Exposure to contrasts phonemic for a community has been said to heighten preverbal infants' sensitivity to these contrasts.This paper argues that phonetic input cannot be specified and ‘experience’ cannot be defined in this context without knowing how infants perceptually structure speech input. Consequently, the discrimination paradigm provides no test for the effect of experience on infants' speech discrimination. The conditions to be met in order to conclude an effect of experience are outlined.

Relationships between speech production and speech perception skills in young cochlear‐implant users

Abstract: The purpose of this investigation was to examine the relationships between young cochlear‐implant users’ abilities to produce the speech features of nasality, voicing, duration, frication, and place of articulation and their abilities to utilize the features in three different perceptual conditions: audition‐only, vision‐only, and audition‐plus‐vision. Subjects were 23 prelingually deafened children who had at least 2 years of experience with a Cochlear Corporation Nucleus cochlear implant, and an average of 34 months. They completed both the production and perception version of the Children’s Audio–visual Feature Test, which is comprised of ten consonant–vowel syllables. An information transmission analysis performed on the confusion matrices revealed that children produced the place of articulation fairly accurately and voicing, duration, and frication less accurately. Acoustic analysis indicated that voiced sounds were not distinguished from unvoiced sounds on the basis of voice onset time or syllabic duration. Subjects who were more likely to produce the place feature correctly were likely to have worn their cochlear implants for a greater length of time. Pearson correlations revealed that subjects who were most likely to hear the place of articulation, nasality, and voicing features in an audition‐only condition were also most likely to speak these features correctly. Comparisons of test results collected longitudinally also revealed improvements in production of the features, probably as a result of cochlear‐implant experience and/or maturation.

Induction of rate-dependent processing by coarse-grained aspects of speech

Abstract: This study investigated the idea that human speech recognition can involve analyzing the speech signal at multiple levels of resolution, using the information obtained from relatively coarse levels of analysis as a context for interpreting detailed acoustic cues to segment identity. Three experiments examined the effectiveness of coarse-grained aspects of speech in inducing rate-dependent processing of closure duration as a cue to phonological voicing in a medial stop consonant (specifically, rabid vs. rapid). Experiment 1 showed that the rate of articulation of a severely filtered precursor phrase influenced voicing judgments about a segment in an unfiltered test word. Experiment 2 showed a similar effect when the amplitude envelope of the precursive speech was filled with a constant-frequency sine wave set at the fundamental of the test word. The contextual effects of these coarse-grained aspects of speech did not differ from those of acoustically detailed precursive speech. Experiment 3 showed that no context-dependent processing occurred when the amplitude envelope of the precursive speech was filled with white noise, indicating that the precursive sounds must have some acoustic continuity with the test word for integration to take place. The results support the idea that context-dependent processing can be based on coarse aspects of the speech signal.
