Purpose: Many communication disorders result in speech sound errors that listeners perceive as phonemic errors. Unfortunately, manual methods for calculating phonemic error frequency are prohibitively time consuming to use in large-scale research and busy clinical settings. The purpose of this study was to validate an automated analysis based on a…

Purpose: Motor neuron diseases, such as amyotrophic lateral sclerosis (ALS), have a devastating effect on speech muscle function that often results in severe communication deficits. Over the course of bulbar disease, tongue and jaw movements are modified, but their impact on speech is poorly understood. The aim of this study was to determine the…

Background: There is a growing body of evidence that speech and language therapy (SLT) intervention is effective in improving communication ability for individuals with non-progressive acquired apraxia of speech (AOS). However, there is no universally agreed diagnostic standard for AOS, and diverging opinions on its diagnostic features. This has…

Purpose: The aim of this study was to determine the relation of tongue--jaw coupling to phonetic distinctiveness of vowels in persons at different stages (i.e., early, middle, late) of bulbar motor involvement in amyotrophic lateral sclerosis (ALS) and healthy controls. Method: The pattern of spatial tongue-jaw coupling was derived from 11…

Stuttering is a disorder that affects about 1% of the population and manifests as speech disfluencies. Reading difficulties and disabilities are commonly found in this population. Nonetheless, speech disfluencies have not been explored in adult struggling readers (ASRs). In the current study, we examined the rate of stuttering in ASRs as well as…

Purpose: Recent proposals suggest that (a) the high dimensionality of speech motor control may be reduced via modular neuromuscular organization that takes advantage of intrinsic biomechanical regions of stability and (b) computational modeling provides a means to study whether and how such modularization works. In this study, the focus is on the…

The purpose of the article was to analyze the psychological and pedagogical conditions of word-formation skills for Kazakh-speaking preschool children with speech disorders on the basis of learning theories and contemporary approaches. To achieve the set aim, we have studied psychophysiological peculiarities of preschool children with speech…

It is known that many methods including voice training practices are used in the improvement of stuttering. With the studies carried out for this purpose, it is aimed to relieve the individual from feelings such as lack of self-confidence, anxiety, and embarrassment, as well as to support the education life and literacy experiences of the…

Purpose: While the involvement of attention in utterance planning is well established at the conceptual and lexical levels, the attentional demands of postlexical processes are still debated. This study investigates the involvement of attentional resources on motor speech encoding during utterance production in the context of Parkinson's disease…

Purpose: The Motor Planning Theory of Prosody and reading prosody research indicate that "out of the blue" oral reading, as practiced in clinical and research settings, invokes surface rather than covert prosody, particularly when readers are recorded, less skilled, and/or speech impaired. Warm-up is not considered in passage reading for…

Background: Communication and cognitive impairments are known barriers to shared decision-making. Most people diagnosed with motor neurone disease (MND) will develop a motor speech impairment over the disease course. Some will develop cognitive, linguistic or behavioural disturbance. Despite this, the impact of communication and cognitive…

Purpose: The aim of this study was to compare word-initial and word-final consonant cluster productions in young children who speak African American English (AAE) and compare their productions to what we know about cluster productions in children who speak Mainstream American English (MAE), in order to minimize misdiagnosis of speech sound…

Although perseverative speech is a common characteristic of individuals with high-functioning neurodevelopmental disabilities, little is known about the operant functions of these verbalizations. We conducted analogue functional analyses of perseverative speech for 2 students using reinforcement contingencies that included alone, attention,…

Purpose: The ability to recognize individuals from their vocalizations is an important trait of human beings. In the current study, we aimed to examine how congenital amusia, an inborn pitch-processing disorder, affects discrimination and identification of talkers' voices. Method: Twenty Mandarin-speaking amusics and 20 controls were tested on…

Imprecise articulation is the major issue reported in various types of dysarthria. Detection of articulation errors can help in diagnosis. The cues derived from both the burst and the formant transitions contribute to the discrimination of place of articulation of stops. It is believed that any acoustic deviations in stops due to articulation…
