Over the past couple of decades, research has established that infants are sensitive to the predominant stress pattern of their native language. However, the degree to which the stress pattern shapes infants' language development has yet to be fully determined. Whether stress is merely a cue to help organize the patterns of speech or whether it is…

This study explores the question of whether native and nonnative listeners, some familiar with the language and some not, differ in their accent ratings of native speakers (NSs) and nonnative speakers (NNSs). Although a few studies have employed native and nonnative judges to evaluate native and nonnative speech, the present study is perhaps the…

Contends that the acquisition of fluent reading competency involves beginning readers' tacit recognition that they must learn to compensate for the absence of prosodic cues in the written signal by making use of the cues that are preserved. (HOD)

Features associated with the production of linguistic prosody were investigated in seven young speech-disordered children and seven young children with age-appropriate speech abilities. The primary differences between groups were in time characteristics of imitated responses. Results are discussed in terms of physiologic and/or linguistic…

Infants heard sentences in which prosodic structure was either consistent or inconsistent with the syntactic structure. Results suggest that the prosodic information in an individual sentence is not always sufficient to assign a syntactic structure and that learners must engage in active inferential processes to arrive at the correct syntactic…

Retaining detailed representations of unstressed syllables is a logical prerequisite for infants' use of probabilistic phonotactics to segment iambic words from fluent speech. The head-turn preference study was used to investigate the nature of English- learners' representations of iambic word onsets. Fifty-four 10.5-month-olds were familiarized…

Many languages exhibit constraints on prosodic words, where lexical items must be composed of at least two moras of structure, or a binary foot. Demuth and Fee (1995) proposed that children demonstrate early sensitivity to word-minimality effects, exhibiting a period of vowel lengthening or vowel epenthesis if coda consonants cannot be produced.…

This paper investigates the acquisition of prosodic words in European Portuguese (EP) through analysis of grammatical and statistical properties of the target language and child speech. The analysis of grammatical properties shows that there are solid cues to the prosodic word (PW) in EP, and the presence of early word-based phonology in child…

The evidence on the acquisition of intonation by children is reviewed. Reports on the early use of pitch contours fall into two categories, imitational and differential intonation. While imitational intonation is based on mimicry of adults, differential intonation involves the acquisition of two or three tunes that contrast in meaning from an…

This case study examined prosodic use in a normally developing child between the ages of 20 and 46 months. Conversational repairs were elicited to examine prosodic stress. Fundamental frequency, intensity, and duration of syllables were measured. Although the subject could repair stress errors, a clear pattern of the development of acoustic cues…

This study examined falling tone and final syllable lengthening in the spontaneous speech of 10 4-year-old children with specific language impairment (SLI). The falling tone was observed in 9 of the 10 SLI children, despite deficits in segmental phonology, morphosyntax, and mean length of utterance, suggesting a possible dissociation between…

This paper tested a theory of syllable prominence with 11 children (ages 11 to 26 months). The theory proposes that syllable prominence is a product of two orthogonal suprasegmental systems: stress/accent peaks and phrase boundaries. Use of the developed prominence scale found it parsimoniously accounted for observed biases in syllable omissions…

The production of unstressed vowels in English by early and late Korean- and Japanese-English bilinguals was investigated. All groups were nativelike in having a lower fundamental frequency for unstressed as opposed to stressed vowels. Both Korean groups made less of an intensity difference between unstressed and stressed vowels than the native…

A case study of a 2-year-old progressing normally in speech development provides evidence of suprasegmental marking of the plural, thought to be adopted only in language-impaired children. Acoustic analyses of the durations and intensity of elicited words indicate that the child had adopted a suprasegmental strategy for marking the singular/plural…

The acoustic features and functions of accentuation in French are discussed, and features of accentuation in the speech of French 2-year-olds are explored. The four major acoustic features used to signal accentual distinctions are fundamental frequency of voicing, duration of segments and syllables, intensity of segments and syllables, and…
