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…

Speech production studies have shown that the phonological form of a word is made up of phonemic segments in stress-timed languages (e.g., Dutch) and of syllables in syllable timed languages (e.g., Chinese). To clarify the functional unit of mora-timed languages, the authors asked native Japanese speakers to perform an implicit priming task (A. S.…

This paper reports two studies of young English-speaking children's ability to cope with changes to the metrical stress pattern of spoken words and the relationship between this ability, phonological awareness and early reading development. Initially, 39 children aged 4 and 5 years were assessed on their ability to identify mispronounced words,…

Prosodic, or expressive, reading is considered to be one of the essential features of the achievement of reading fluency. The purpose of this study was to determine (a) the degree to which the prosody of syntactically complex sentences varied as a function of reading speed and accuracy and (b) the role that reading prosody might play in mediating…

This study investigated the effects of age, hearing loss, and cochlear implantation on mothers' speech to infants and children. We recorded normal-hearing (NH) mothers speaking to their children as they typically would do at home and speaking to an adult experimenter. Nine infants (10-37 months) were hearing-impaired and had used a cochlear…

Previous research indicates that foreign language learners are much more focused on accuracy, particularly grammatical accuracy, than their teachers are. The purpose of the current study was to gain a more detailed understanding of American learners' views of the need for accuracy in the oral production of a foreign language (German) by (a)…

In this study the influence of prosodic foot structure on the processing of weak syllables in children with cochlear implants (CI) was investigated. A battery of tests investigating processing of weak syllables in single and multiword utterances was carried out on four groups of children: 15 children with CI developing spoken language as expected…

It is acknowledged that contrast plays an important role in understanding discourse and information structure. While it is commonly assumed that contrast can be marked by intonation only, our understanding of the intonational realization of contrast is limited. For German there is mainly introspective evidence that the rising theme accent (or…

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…

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…
