Purpose: Auditory training has been shown to reduce rater variability in perceptual voice assessment. Because rater variability is also a central issue in the auditory-perceptual assessment of dysarthria, this study sought to determine if training produces a meaningful change in rater reliability, criterion validity, and scaling magnitude of four…

Purpose: The StartReact effect, whereby movements are elicited by loud, startling acoustic stimuli (SAS), allows the evaluation of movements when initiated through involuntary circuitry, before auditory feedback. When StartReact is applied during poststroke upper extremity movements, individuals exhibit increased muscle recruitment, reaction…

Purpose: Facial transplantation involves partial or total replacement of neuromuscular and skeletal structures of the face, head, and neck using donor tissues and is among the most extensive facial reconstructive procedures. This case report compares changes in speech production and articulator movement in a 44-year-old man from pretransplant to a…

Purpose: Kinematic measurements of speech have demonstrated some success in automatic detection of early symptoms of amyotrophic lateral sclerosis (ALS). In this study, we examined how the region of symptom onset (bulbar vs. spinal) affects the ability of data-driven models to detect ALS. Method: We used a correlation structure of articulatory…

Purpose: Children with dysarthria secondary to cerebral palsy may experience reduced speech intelligibility and diminished communicative participation. However, minimal research has been conducted examining the outcomes of behavioral speech treatments in this population. This study examined the effect of Speech Intelligibility Treatment (SIT), a…

Purpose: The purpose of this study was to explore the extent to which child- and therapy-level factors contribute to gains in speech sound production accuracy for children with speech sound disorders in receipt of school-based services. Method: Data were obtained from 126 kindergarten and first- and second-grade children currently in receipt of…

Purpose: The purpose of this study was to determine the extent to which school-age children with speech sound disorder (SSD) exhibit concomitant reading difficulties and examine the extent to which phonological processing and speech production abilities are associated with increased likelihood of reading risks. Method: Data were obtained from 120…

Purpose: Children with a cleft palate (± cleft lip; CP±L) can have difficulties communicating and participating in daily life, yet speech-language pathologists typically focus on speech production during routine assessments. The International Classification of Functioning, Disability and Health: Children and Youth Version (ICF-CY; World Health…

This paper analyses consonant articulation errors in dysarthric speech produced by seven American-English native speakers with cerebral palsy. Twenty-three consonant phonemes were transcribed with diacritics as necessary in order to represent non-phoneme misarticulations. Error frequencies were examined with respect to six variables: articulatory…

Purpose: To assess the effects of short- and long-term changes in auditory feedback on vowel and sibilant contrasts and to evaluate hypotheses arising from a model of speech motor planning. Method: The perception and production of vowel and sibilant contrasts were measured in 8 postlingually deafened adults prior to activation of their cochlear…

Twenty-two six-year-olds who misarticulated word-initial [r] as [w] were compared with 13 age-matched normally articulating children on ability to identify and discriminate seven synthetic stimuli representing an acoustic continuum between [we] and [re]. Results indicate that a majority of the misarticulating children have failed to phonemically…

The study examined the frequency of occurrence of velar deviations in spontaneous single-word utterances over a six-month period for 40 children (2 to 3-years-old). Results indicated that velars presented difficulty for less than half of the children. Velar difficulty was associated with position in the word and the vowel environment. (Author/DB)

In the past years, there have been an increasing number of instrumental investigations as to the nature of speech production errors, prompted by the concern that decades of transcription-based speech error data may be tainted by perceptual biases. While all of these instrumental studies suggest that errors are not, as previously thought,…

The study investigated selected articulation characteristics of 8- to 12-year-old children with severe hearing impairments and the relations between these characteristics and judged adequacy of spontaneous conversational speech. Correlational analyses suppport the usefulness of a single index such as that derived from a comprehensive articulation…

Ten esophageal speakers and ten normal speakers produced repetitions of the disyllable /mama/ using five different conditions of syllable stress. Nine normal listeners judged both relative and absolute syllable stress. Reliable judgments were made of the syllable stress, and speakers were able to effect systematic changes in listener perceptions…
