Background noise challenges auditory recognition of speech and may reveal the underlying deficits in auditory word recognition skills. Previous studies have reported an association between children's auditory skills and various linguistic skills, including phonology, although in some languages only. However, language-specific features influence…

The influence of motor knowledge on speech perception is well established, but the functional role of the motor system is still poorly understood. The present study explores the hypothesis that speech production abilities may help infants discover phonetic categories in the speech stream, in spite of coarticulation effects. To this aim, we…

Results of this study suggest that, for primary level children, the natural'' perceptual unit of spoken language is the syllable, not the phoneme. (Authors)

This study investigated the relationship between perception and production in children's phonological learning to determine whether perceptual confusions could account for the patterns of substitution and deletion found in 2-year-olds' speech. A total of 14 children were presented pairs of toy stimuli, with each pair composed of a familiar item…

This paper takes issue with the position that children's phoneme acquisition schedule is dictated primarily by auditory perceptual factors and suggests the alternative position that ease of production accounts for age of acquisition. It is felt that perceptual theory cannot adequately explain phonological development, e.g. three-year-olds produce…

This report is one of a regular series on the status and progress of studies on the nature of speech, instrumentation for its investigation, and practical applications. The ten papers treat the following topics: speech synthesis as a tool for the study of speech production; the study of articulatory organization; phonetic perception; cardiac…

A distinction is made between the acquisition of phonetics and of phonology. Their interaction and the ways in which they interfere with each other are discussed. Data on the acquisition of English fricatives for several children are given, and are analyzed separately for the phonological and phonetic aspects of acquisition. (Author/CLK)

Adults and 4-year-old children were tested to determine whether the children were able to decode sets of familiar minimal pairs as well as adults. They listened to words spoken in a normal voice and a whisper. Indications were that the 4-year-old's perceptual mastery of English phonology is not yet complete. (SW)

Perception and production data were collected from 28 children, ages 1 year 8 months to 3 years 11 months to test four specific hypotheses on the acquisition of initial fricatives and glides in English, based on the assumptions that perception precedes production and unmarked precedes marked. Perception data were collected by the Shvachkin-Garnica…

The effects of certain linguistic dimensions on auditory blending performance and training were examined. Dimensions included type of phonological context, consonant-vowel or vowel-consonant (CV or VC); units to be blended, syllables or phonemes (S or P); and size of units, single or double. Six ordered 96-word training blends were administered to…

Identification of correctly produced and misarticulated /w,r,l,j/ was examined in 12 children, aged 3:6-7:5. The children, their parents, and raters were more successful in identifying correctly produced semivowels than misarticulated ones. Both normal children with developmental substitutions and articulation-impaired children demonstrated…

Reports on two experiments, one performed on infants, the other on adults, designed to examine the issue of categorical perception of speech contrasts in infants in relation to linguistic processing and the innateness theory of speech perception. (AM)

Stampe's (1969, 1973) hypotheses regarding innate mental phonological processes are tested against some of the extant data on speech perception. (AM)

Reports on the perceptual discrimination of segmental and suprasegmental phones by Japanese learners of English. Results reveal that early learners showed better discrimination performance than normal learners and confirmed the usefulness of learning English at an early age. (16 references) (Author/CK)

Explores one aspect of the possible relationship between speech perception and the awareness of linguistically relevant sound patterns in the first years of word reading. No evidence emerged of a concurrent association between children's skills in labelling speech sounds at the beginning of words and their phonological awareness of either rhyme or…
