Clear versus casual consonant identification by hearing-impaired and normal-hearing listeners.
This study examined the intelligibility of 21 amplified, casually- and clearly-spoken, US English coda consonants in nonsense syllables for 10 normal-hearing (NH) and 17 HI listeners. Most clear-speech consonants yielded higher recognition scores as expected. However, certain phonological processes common in casual speech, such as palatalization of higher frequency alveolar into lower frequency postalveolar consonants, generated significantly higher scores than their clear counterparts for some HI listeners in noise. These results have implications for coaching conversational partners of aided HI listeners. For the militar...

Phonological awareness and sonority in Greek children: developmental data and clinical perspectives.
In this study, we investigate whether sonority theory can account for the developmental patterns of phoneme awareness skills in Greek. To that end, 40 preschool and first grade children carried out an offline metaphonological task that involved the initial consonant deletion of two-consonant clusters. Overall, children's performance was in line with the sonority sequencing principle (SSP); consonant clusters that display a maximal rise in sonority were easier to manipulate compared to clusters with minimal sonority difference or SSP-violating clusters. Affricates generated the highest number of errors, a finding that stren...

Estimates of functional cerebral hemispheric differences in monolingual and bilingual people who stutter: dichotic listening paradigm.
Abstract Recent studies indicate functional cerebral hemispheric processing differences between monolinguals and bilinguals who stutter, as well as monolinguals and bilinguals who do not stutter. Eighty native German speakers, half of whom were also proficient speakers of English as a second language (L2), were assessed on a dichotic listening paradigm using CV syllables as stimuli. The participants were organised into four different groups according to speech status and language ability: 20 monolinguals who stutter, 20 bilinguals who stutter, 20 monolinguals who do not stutter, and 20 bilinguals who do not stutte...

To initiate repair or not? Coping with difficulties in the talk of adults with intellectual disabilities.
Abstract How do health and social care professionals deal with undecipherable talk produced by adults with intellectual disabilities (ID)? Some of their practices are familiar from the other-initiated repair canon. But some practices seem designed for, or at least responsive to, the needs of the institutional task at hand, rather than those of difficult-to-understand conversational partners. One such practice is to reduce the likelihood of the person with ID issuing any but the least repair-likely utterances, or indeed having to speak at all. If they do produce a repairable turn, then, as foreshadowed by earlier w...

Abstract Canonical babbling and volubility are common indicators of infant vocal development. If either indicator falls below values found in typical infants, it may be an early signal of a developmental disorder. The aim of this retrospective investigation was to examine home videos for the frequency of canonical babbles, age of canonical babbling onset, and overall volubility of eight infants later diagnosed with childhood apraxia of speech and compare these data to that of six typically developing infants as well as four infants later diagnosed with a speech sound disorder.

Considerations for Chinese text input methods in the design of speech generating devices: a tutorial.
Abstract Millions of Chinese-speaking people who have the most severe speech disorders could potentially benefit from using Speech Generating Devices (SGDs) to help them participate in society. Entering Chinese text into computer systems is complex, and the process itself requires a translation system from the small selection set of keys to Chinese characters, thus adding to the complexities of adaptive access to computers often required by people who rely on them for spoken and written communication. This paper examines two types of input method: those relying on phonetic principles, and those relying on logograp...

This article investigated the role of semantic transparency in processing root compound nouns in Persian individuals with Broca's aphasia through picture confrontation naming and repetition tasks. The relationship between semantic transparency and affected constituents of nouns showed that semantic transparency had no role in processing compound nouns. The results showed that transparent, opaque and partially transparent compound nouns were processed by dual-routes (holistic and decomposing). Frequency of errors also revealed dissociation of naming and repetition processes as well as simple and compound nouns. The comparis...

Do shared semantic features facilitate Lexical-semantic processing in early course psychosis?
Abstract The lexical-semantic relatedness effect supposes different activation in the semantic memory of related versus unrelated word-pairs. Semantically related pairs are considered to result in a larger spread of activation as the activation of concept nodes is dependent on shared lexical-semantic features of concepts. The increased activation of concepts in the semantic memory in individuals with schizophrenia is found to be, faster spreading and lacking in inhibition in relation to healthy control subjects. The aim of this study was to examine whether the lexical-semantic relatedness effect influences process...

In this study, we examine the single-word productions of 275 children with phonological disorder from the Learnability Project (Gierut, 2015b) to confirm the relationship between phonemic inventory - a measure of phonological knowledge - and consonant accuracy - a quantitative, relational measure that directly compares a child's phonological productions to the target (i.e. adult-like) form. Further, we identify potential percentage accuracy cutoff scores that reliably classify sounds as in or out of a child's phonemic inventory in speech-sound probes of varying length. Our findings indicate that the phonemic function of up...

The goals of the present research were to obtain information on the phenotype of SMD and initial information on the persistence of SMD in children receiving treatment for idiopathic Speech Delay (SD). Five questions about the phenotype and persistence of SMD were posed using a database of audio-recordings and participant records and longitudinal data from audio-recording...

Estimates of the prevalence of speech and motor speech disorders in persons with complex neurodevelopmental disorders.
Abstract Estimates of the prevalence of speech and motor speech disorders in persons with complex neurodevelopmental disorders (CND) can inform research in the biobehavioural origins and treatment of CND. The goal of this research was to use measures and analytics in a diagnostic classification system to estimate the prevalence of speech and motor speech disorders in convenience samples of speakers with one of eight types of CND. Audio-recorded conversational speech samples from 346 participants with one of eight types of CND were obtained from a database of participants recruited for genetic and behavioural studi...

Dissociation between speech modalities in a case of altered accent with unknown origin.
We present a case of sudden onset, acquired altered accent in the speech of NL, a 48-year-old, left-handed female. NL's typical Standard Southern British English accent was preserved in singing and reading, but altered in recitation, repetition and spontaneous speech. Neuropsychological investigation, impressionistic and acoustic analysis of accented and unaccented speech are documented. The altered accent displays a slower speech rate and longer duration of consonants and vowels. There is evidence for a shift towards syllable-timed rhythm. NL's altered accent displays atypical coordination between voicing and supra-laryng...

Dealing with the unknown - addressing challenges in evaluating unintelligible speech.
gsson S Abstract When investigating the interaction between speech production and intelligibility, unintelligible speech portions are often of particular interest. Therefore, the fact that the standard quantification of speech production - the Percentage of Consonants Correct (PCC) - is only computed on intelligible speech is unsatisfying. Our purpose was to evaluate a new quantification of speech production: the Percentage of Intelligible and Correct Syllables (PICS) designed to address this limitation. A secondary purpose was to explore a task designed to elicit connected speech - concurrent commenting - offerin...

Phonological and phonetic impairment in aphasic speech: an acoustic study of the voice onset time of six French-speaking aphasic patients.
Abstract The aim of the present study is to contribute to the description of the speech production deficits in French-speaking aphasic patients, so as to shed light on their potential phonetic and/or phonological disorders. Acoustic studies of aphasics' speech productions remain relatively infrequent, especially in French, and when entering into the specifics, often lead to inconsistent results. We conducted a multiple-case study on six aphasic patients, four with non-fluent aphasia and two with fluent aphasia. They were administered a variety of language and neuropsychological tasks, then they participated in a c...

How do persons with apraxia of speech deal with morphological stress in Spanish? A preliminary study.
te; L Abstract Equal stress across adjacent syllables and extended syllable durations are amongst the most salient features of acquired Apraxia of Speech (AOS). Most studies conclude that there is a deficit in durational cue processing, whereas the other acoustic stress correlates remain relatively unimpaired. Spanish is a free-stress language in which stress patterns are contrastive, especially in verbal forms (e.g. lavo /'labo/ '[I] wash' vs lavó /la'bo/ '[He/she] washed'). The aim of this preliminary study is to determine whether persons with AOS are able to make the intended stress pattern identifiable ...

Study of tongue-palate pressure patterns during the hold phase in the production of French denti-alveolar and velar stops.
Abstract The hold phase of the stop consonants is crucial for a successful production of the release and the acoustic burst. Concurrently, it is also associated with weak acoustic energy and minimal movement, so that conventional acoustic and kinematic approaches are not relevant to investigate motor control. This paper presents an innovative experimental method to study speech motor control during this phase, based on meticulous measurement of the time variation of the mechanical pressure exerted by the tongue against the palate and also characterizing tongue-palate interaction. The concept is based on using mini...
