Examines metrical segmentation strategy in Dutch. The first experiment shows that stress strongly affects Dutch listeners' ability and speed in spotting Dutch monosyllabic words in disyllabic nonwords. The second experiment finds the same stress effect when only the target words are presented without a subsequent syllable triggering segmentation.…

Compared disyllabic sequences from infants and adults according to their use of frequency, intensity, and duration to mark stress. Concluded that infants in English language environments produce adult-like stress patterns before they produce lexical items, which specify stress. Acoustic and perceptual analyses indicated infants use three acoustic…

In this study, seven children with specific language impairment (SLI) and speech deficits were matched with same age peers and evaluated for iambic (weak-strong) and trochaic (strong-weak) prosodic speech forms. Findings indicated that children with SLI and speech deficits show less mature segmental and speech motor systems, as well as decreased…

Impaired speech prosody has been identified as a critical feature of suspected childhood apraxia of speech (sCAS). Lexical stress productions of children with sCAS have been characterized as 'excessive/equal/misplaced'. This investigation examines two potential explanations of this particular deficit, articulatory difficulty and impaired intrinsic…

Spoken language comprehension requires the coordination of different subprocesses in time. After the initial acoustic analysis the system has to extract segmental information such as phonemes, syntactic elements and lexical-semantic elements as well as suprasegmental information such as accentuation and intonational phrases, i.e., prosody.…

Speakers with autism spectrum disorders (ASD) show difficulties in suprasegmental aspects of speech production, or "prosody," those aspects of speech that accompany words and sentences and create what is commonly called "tone of voice." However, little is known about the perception of prosody, or about the specific aspects of…

Research on nonverbal vocal cues and verbal irony has often relied on the concept of an "ironic tone of voice". Here we provide acoustic analysis and experimental evidence that this notion is oversimplified and misguided. Acoustic analyses of spontaneous ironic speech extracted from talk radio shows, both ambiguous and unambiguous in…

Purpose: Prosodic cues are used to clarify sentence structure and meaning. Two studies, one of children with specific language impairment (SLI) and one of adults with a history of learning disabilities, were designed to determine whether individuals with poor language skills recognize prosodic cues on par with their normal-language peers. Method:…

The word length effect has been a central feature of theorising about immediate memory. The notion that short-term memory traces rapidly decay unless refreshed by rehearsal is based primarily upon the finding that serial recall for short words is better than that for long words. The decay account of the word length effect has come under pressure…

The present investigation focussed on the neural substrates underlying linguistic distinctions that are signalled by prosodic cues. A production experiment was conducted to examine the ability of left- (LHD) and right- (RHD) hemisphere-damaged patients and normal controls to use temporal and fundamental frequency cues to disambiguate sentences…

Language learning requires a capacity to recall novel series of speech sounds. Research shows that prosodic marks create grouping effects enhancing serial recall. However, any restriction on memory affecting the reproduction of prosody would limit the set of patterns that could be learned and subsequently used in speech. By implication, grouping…

This study explores sound-symbolic, or mimetic, words in the Japanese language, the majority of which are never entered in Japanese dictionaries, and which may not be fully understood in all their nuances by native speakers. The extensiveness of the sound-symbolic system is related to the semantic under-differentiation of Japanese verbs. An…

A study investigated the order of acquisition of inflectional morphology in English within morphemes, focusing on late acquisition of one allomorph of the plural. It is proposed that late acquisition is rooted in the operation of the Obligatory Contour Principle (OCP), which states that at the melodic level, adjacent identical elements are…

Both Italian and English have four degrees of stress: emphatic, main, secondary and weak. This paper outlines some similarities, then reviews differences between the languages that can cause difficulties in learning the second language. (CHK)

A study of the phonetic changes occurring when a speaker attempts to revise an unclear word for a listener focuses on changes made in the sound segment duration to maximize differences between phonemes. In the study, five-year-olds were asked by adults to revise words differing in voicing of initial and final stop consonants; a control group of…
