Speech intelligibility loss due to amyotrophic lateral sclerosis: the effect of tongue movement reduction on vowel and consonant acoustic features.
Abstract The purpose of this study was to identify aspects of impaired tongue motor performance that limit the ability to produce distinct speech sounds and contribute to reduced speech intelligibility in individuals with dysarthria secondary to amyotrophic lateral sclerosis (ALS). We analyzed simultaneously recorded tongue kinematic and acoustic data from 22 subjects during three target words (cat, dog, and took). The subjects included 11 participants with ALS and 11 healthy controls from the X-ray microbeam dysarthria database (Westbury, 1994). Novel measures were derived based on the range and speed of relative...

Consonant and vowel production in the spontaneous speech productions of children with auditory brainstem implants.
Abstract Auditory brainstem implantation provides hearing sensations in children and adults with anomalies of the auditory nerves. In children, perceptual benefits have been established, and research already demonstrated (limited) effects on children's speech production. The current study extends the literature by scrutinizing the phonological development of three children with ABI. Spontaneous speech samples were used to establish their phonemic inventories of vowels, word-initial consonants and word-final consonants, both independently of the target phoneme and relative to the target phoneme. The three children ...

Language assessment in awake brain surgery: the Portuguese adaptation of the Dutch linguistic intraoperative protocol (DuLIP).
Abstract Awake brain surgery, combined with neurophysiological evaluation and intraoperative mapping, is one of the preferential lines of treatment when approaching low-grade gliomas. Speech and language assessment is used while applying Direct Electrical Stimulation (DES) and during the resection of a lesion/tumour, as it allows to establish related eloquent areas and optimise the extent of the resection and avoid impairments. Patients need to be assessed pre, intra and post-surgery, but in under resourced countries such as Portugal, there are still no standardised and validated tools to conduct this type of eval...

Phonetic complexity and stuttering in Turkish-speaking children who stutter.
Abstract The relationship between stuttering and phonetic complexity for words spoken by Turkish children who stutter was investigated. The research questions were: (1) Do Turkish-speaking children stutter more on unbound content words than on unbound function words? (2) Do Turkish-speaking children stutter more on words with higher phonetic complexity scores? Twenty-one monolingual children aged 6-11 years who had a clinical diagnosis of stuttering participated. Speech samples were transcribed and lexical categories determined. Phonetic complexity was assessed by an adaptation of Index of Phonetic Complexity...

Simplification of syllable structure in childhood apraxia of speech: a 2-year follow-up French case study.
Abstract Although Childhood Apraxia of Speech (CAS) has been extensively investigated in the clinical literature, most of the findings regarding impairments in the production of syllable structure, recorded within this population, have been mainly focused on English. The main purpose of this two-year follow-up case study was, therefore, to examine whether syllable complexity may be considered as a robust indicator in CAS and whether it can explain the persistence of errors and, if so, at what age. This was tested in a boy followed up annually from age 5 to 7 who was administered a narrative task. Data analyses use...

Consonant cluster acquisition in Chilean children with typical and protracted phonological development.
The objectives were to analyze accuracy of CCs and mismatch (error) patterns as a function of age (4/ 5 years) and TD/PPD group, examining effects of sonority, stress, place of articulation and development of /l/ and /ɾ/ as singletons. Participants included 20 Chilean Spanish-speaking children with TD and 20 with PPD (ages 4 and 5 years). The TD group showed higher accuracy and an age effect. For both developmental groups, timing unit match was higher than full segmental match. CCs with labial and voiceless C1s in stressed syllables were most accurate. In the PPD group, deletions predominated over substitutions,...

Agreement between Transcription- and Rating-Based Intelligibility Measurements for Evaluation of Dysphonic Speech in Noise.
Abstract Dysphonia negatively affects a speaker's intelligibility, especially in noisy environments. Previously, our study showed this effect of dysphonia with the transcription-based intelligibility measurement. While this finding indicates the importance of intelligibility assessment for this population, implementing the transcription-based measurement may be difficult in clinical settings due to its resource-demanding nature. Using the same speakers, this study examined the agreement between transcription- and rating-based intelligibility measurements. Six sentences from the Consensus of Auditory-Perceptual Eva...

The development of Thai monosyllabic word and picture lists applicable to interactive speech audiometry in preschoolers.
Abstract Interactive speech audiometry is the assessment of speech comprehension and phonological discrimination through automated means. In order for the performance of such assessments in preschoolers to be successful, the employed list of words and pictures must be easily recognized both linguistically and visually. That is, the children must be able to easily associate the sound they hear with the picture they see with a high degree of certainty. To this end, a Thai monosyllabic word and picture list called NCU-20 (NECTEC-CU-20) is proposed. The word lists for Thai vowel and consonant hearing tests are designe...

Abstract Auditory brainstem implants (ABI) in children in the first years of life is a recent innovation. Analyses of their speech and language development on the basis of spontaneous language samples are still largely lacking. The aim was to investigate the phonological complexity of the words children with ABI use in their spontaneous speech, and to compare their accuracy with that of children with cochlear implants (CI) and children with normal hearing (NH). Longitudinal recordings of spontaneous speech were collected of three children with ABI. Children with ABI target mainly words of low phonological complexi...

Fast mapping of verbs in Afrikaans-speaking children from low and mid socioeconomic backgrounds and children with language impairment.
Abstract Children with LI are at a disadvantage because they typically have smaller vocabularies than their TD peers. However, children from low-SES households often also have smaller vocabularies and can thus be misdiagnosed with LI. The purpose of this study was to compare the fast-mapping (FM) skills of 3 groups of 4- to 9-year-olds: typically developing (TD) children with low socioeconomic status (SES) and mid SES, and mid-SES children with language impairment (LI), to ascertain whether FM is affected by SES.

Previously, we sketched how the prevailing concepts and measurement practices employed in research and speech pathology practice for communication disorders have framed the real-time accomplishment of co-present communication, and contrasted them with its observable properties. We also proposed that distinctive aspects of communication disorders could be divided into three conceptual/causal frames: microgenetic, synchronic, and enchronic. The enchronic frame aligns with the real-time accomplishment of communication, captur...

Production of third-person direct object clitics in children with cochlear implants speaking Italian.
Abstract Previous research has shown that the production of third-person singular accusative object clitics (3DO clitics) might be taxing in Italian-speaking pre-school children with cochlear implants (CIs). We investigated this topic by assessing 3DO clitic production in 14 children with an average age of 8 years, who had received CI between age 1 and 4. The first goal of the study was to analyze whether school-aged children with CIs exhibit atypical behavior in 3DO clitic production. The second goal was to analyze whether children with CIs are prone to agreement errors in case of gender mismatch between the...

Categorical perception of speech sounds in adults who stutter.
This study aimed to extend our previous research to adults who stutter (AWS) using the same categorical perception paradigm. Fifteen AWS and 15 adults who do not stutter (A WNS) were recruited to complete identification and discrimination tasks involving acoustic variations of Cantonese speech sounds in four stimulus contexts: consonants (varying in voice onset times, VOTs), lexical tones, vowels and pure tones. The results showed similar categorical perception between the two groups in terms of the boundary position and width in the identification task and between-category benefits in the discrimination task. However, the...

The impact of linguistic bias upon speech-language pathologists' attitudes towards non-standard dialects of English.
This study investigates speech-language pathologists' (SLPs) linguistic bias towards non-standard language forms and dialects, and factors that may impact on these attitudes. Language attitude studies reveal that negative attitudes towards variation can lead to bias against speakers of non-standard dialects. If SLPs hold linguistic bias towards speakers of non-standard dialects, this has the potential to impact upon their clinical judgement of difference vs. disorder and lead to inequality of service provision. A total of 129 Australian SLPs completed an online survey, which involved ranking 28 attitudinal statements regar...

Measuring word-final consonant clusters in developmental child speech.
Abstract The correlation between the measure for cluster proximity (MCP) and the percentage of consonants correct (PCC) for word-initial two-member consonant clusters was recently found in the literature to be strong and statistically significant in developmental child speech. Because of this, MCP norms that quantitatively define stages in cluster development (omission, reduction, vowel epenthesis, and two-member production with a distinction on member accuracy) can be predicted from PCC norms that only measure cluster-member accuracy. In the present study, this investigation is extended to word-final two-member c...

Voice onset time and formant onset frequencies in Arabic stuttered speech.
Abstract Neuromuscular models of stuttering consider that making transitions between phones results in inappropriate temporal arrangements of articulators in people who stutter (PWS). Using this framework, the current study examined the acoustic productions of two fine-grained phonetic features: voice onset time (VOT) and second formant (F2). The hypotheses were that PWS should differ from fluent persons (FP) in VOT duration and F2 onset frequency as a result of the transition deficit for environments with complex phonetic features such as Arabic emphatics. Ten adolescent PWS and 10 adolescent FPs participated in ...

Yet, such a description seems crucial in order to better understand the differences between stuttering-like and other disfluencies, and their underlying motor mechanisms. Hence, we aimed to compare the articulatory supraglottic activity in stuttered disfluencies with non-pathological disfluencies by using Electromagnetic Articulography (EMA) data. To achieve this comparison, two criteria were used for the description of articulatory activity during the disfluency. The first focu...

Correlation between the measure for cluster proximity (MCP) and the percentage of consonants correct (PCC).
Abstract A measure was recently proposed for the quantitative evaluation of consonant clusters in child developmental speech, the measure for cluster proximity (MCP). Its advantage over the widely used measure of the percentage of consonants correct (PCC) is that it differentiates the three main stages of cluster production: reduction, vowel epenthesis, and two-members, correct or not. The purpose of the present article is two-fold: a) to contrast MCP and PCC in two-member word-initial clusters produced within children with speech sound disorders (SSDs), tested before and after therapy, as well as in running speec...

Speech exemplar and evaluation database (SEED) for clinical training in articulatory phonetics and speech science.
Abstract One challenge faced by teachers of phonetics, speech science, and clinical speech disorders courses is providing meaningful instruction that closes the theory to practice gap. One barrier to providing this type of deep learning experience is the lack of publicly available examples of speech recordings that illustrate comparisons between typical and disordered speech production across a broad range of disorder populations. Data of this type exist, but are typically collected for specific research projects under narrowly written IRB protocols that do not allow for release of even de-identified speech record...

Cohesion in the discourse of people with post-stroke aphasia.
Abstract Aphasic discourse has been investigated through two major approaches: a micro-linguistic approach and a macro one, but the separate analysis of the micro and macro aspects of aphasic discourse has led to a noticeable gap between them. Cohesion analysis is one of the possible ways that can directly connect these two aspects. However, few studies have investigated cohesion in aphasic discourse in an integrated manner. The present study employs a mixed-methods approach to examine whether and how patients with fluent and non-fluent stroke-induced aphasia differ from normal individuals in the cohesion of their...

Other-initiations of repair by children with developmental language disorder in speech-language therapy and non-institutional play.
This study explores the use of other-initiations of repair by children with developmental language disorder (DLD). The data are children's video-recorded language assessment sessions, speech-language therapy sessions and two kinds of non-institutional play sessions, parent-child and peer play. The videotapes were transcribed following CA conventions focusing on speech and relevant embodied actions. Other-initiations of repair were identified, collected and analyzed. The analysis focuses on open requests and candidate understandings which were the two most common types of other-initiation of repair in the data. The types of...

Profiling variability and development of spoken discourse in mainstream adolescents.
Abstract Competence in spoken discourse is an important consideration during assessment and intervention planning for adolescents with communication difficulties. Currently, a lack of age-appropriate protocols and reference data against which to interpret performance, are barriers when working with this population, particularly those that assess a range of genre and language features. Using a new assessment tool, the Curtin University Discourse Protocol-Adolescent (CUDP-A), this study aimed to collect and describe spoken discourse samples from a large group of adolescents (n = 160), aged 12 to 15 ye...

Prelexical phonetic and early lexical development in German-acquiring infants: canonical babbling and first spoken words.
Abstract Prelexical phonetic capacities have widely been described to be a precursor for later speech and language development. However, studies so far varied greatly in the measurements used for the detection of canonical babbling onset or the description of infants' phonetic capacities at one or more set time points. The comparability of results is, therefore, questionable. Thus, the aims of this study were to investigate the associations between (1) different measurements of CBO, (2) different aspects of phonetic capacity at the age of 9 months and (3) age of CBO and phonetic capacities at 9 months. A...

Correction and turn completion as collaborative repair strategies in conversations following Wernicke's aphasia.
This study explores repair practices deployed by the interlocutor of a speaker with Wernicke's aphasia, their relationship to types of aphasic difficulty, and how mutual understanding and the progression of talk is maintained. A 75-year-old woman with Wernicke's aphasia of 16 months duration and her friend video recorded 36 minutes of conversation at home. Using conversation analytic methods two patterns of other-repair by the non-aphasic interlocutor were identified. The first practice was turn completion, which occurred in the context of self-initiated word search by the person with aphasia. The second was corr...
