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…

Background: Disordered expressive prosody is a widely reported characteristic of individuals with autism. Despite this, it has received little attention in the literature and the few studies that have addressed it have not described its relationship to other aspects of communication. Aims: To determine the nature and relationship of expressive and…

This article discusses reasons for explicit pronunciation instruction, despite the continued neglect of this area in the communicative classroom. "ACTFL/NCATE Program Standards for the Preparation of Foreign Language Teachers (2002)" and "Standards for Foreign Language Learning in the 21st Century" (National Standards, 1999) dictate that teachers…

Purpose: Little is known about the phonological aspects of derivational processes. Neutral suffixes (e.g., "-ness") that do not change stress and rhythmic or nonneutral suffixes (e.g., "-ity") that alter stem stress were used in a production task that explored developmental changes in phonological accuracy of derived English…

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…

A recurring question in the study of the specialized English used in various technical disciplines is the degree to which contextual variables--including subject matter--account for the particular distributions of lexicogrammatical features in texts of different disciplines. Two contextual variables related to role relationships in the semiotic…

This article is a critical review of a number of statistical works, over the past 50 years, dedicated to the determination of the relative frequency of phonemes. (Author/RM)

Field research into the Heiltsuk language, part of the Kwakiutlic branch of the Wakashan language family, in British Columbia is reported. Some of the features of Heiltsuk phonetics are discussed. (RM)
