Purpose: The aim of this study was to use acoustic and kinematic speech measures to characterize type of motor speech impairment--apraxia of speech (AOS) versus dysarthria--in individuals with four-repeat tauopathy (4RT)-associated syndromes, including nonfluent variant primary progressive aphasia (nfvPPA), primary progressive AOS (PPAOS),…

Purpose: The human voice changes with the progression of neurological disease and the onset of diseases that affect articulators, often decreasing the effectiveness of communication. These changes can be objectively measured using signal processing techniques that extract acoustic features. When measuring acoustic features, there are often several…

Effects of phonetically variable input (PVI) for processing instruction (PI) training and the number of training items were tested with a picture-selection eye-tracking task. Intermediate second language (L2) learners of French (n = 174) were tested before and after they received either a short (24 items), medium (48), or long (96) training on the…

Ageing is associated with elevated pure-tone thresholds, accompanied by increased difficulties in understanding speech-in-noise. While amplification provides important, but insufficient support, auditory-cognitive training (ACT) might propose a solution. However, generalized effects have been scarce, highlighting the necessity of training designs…

Background: Around 800 million young children worldwide have cognitive-developmental limitations due to issues related to biological, environmental, and psychosocial factors. These problems lead to educational challenges, limited skill development, and higher unemployment rates. Therefore, timely interventions addressing the underlying problems in…

Purpose: Prelingual deaf children with cochlear implants show lower digit span test scores compared to normal-hearing peers, suggesting a working memory impairment. To pinpoint more precisely the subprocesses responsible for this impairment, we designed a sequence reproduction task with varying length (two to six stimuli), modality (auditory or…

Numerous studies have demonstrated the substantial advantages of integrating music education into the overall development of students, particularly in early childhood education. This integration allows for combining music education with various curriculum areas, utilizing its playful and motivating nature as a practical methodological tool for…

Purpose: The purpose of this study was to examine the short- and longer-term effects (3-month follow-up) of a 1-month intensive straw phonation (SP) therapy on the voice quality and voice-related quality of life of female speech-language pathology (SLP) students with mild dysphonia. Method: Thirty-two female SLP students (mean age: 18.5 years,…

Purpose: Voice and speech are rich with information about a speaker's personality and other features of identity. This study seeks to determine the extent to which listeners agree about speakers' social, physical, and personality attributes. Method: Two experiments were conducted. In the first experiment, listeners rated a group of speakers who…

How do infants learn the sounds of their native language when there are many simultaneous sounds competing for their attention? Adults and children detect when speech sounds change in complex scenes better than when other sounds change. We examined whether infants have similar biases to detect when human speech changes better than nonspeech sounds…

Purpose: This study aimed to gain more insight into the primary auditory abilities of children with significant residual hearing in order to improve decision making when choosing between bimodal fitting or sequential bilateral cochlear implantation. Method: Sound localization abilities, spatial release of masking, and fundamental frequency…

This report is a summary of two studies. In the first, we compared examples of Irish fiddle performances with Western classical violin performances. Acoustical analyses showed that both classical examples produced average spectral centroids higher in frequency, higher harmonic to noise ratios, more use of vibrato, more disjunct intervals, and less…

Prosody is the fundamental organizing principle of spoken language, carrying lexical, morphosyntactic, and pragmatic information. It, therefore, provides highly relevant input for language development. Are infants sensitive to this important aspect of spoken language early on? In this study, we asked whether infants are able to discriminate…

The purpose of this study is to compare the levels of playfulness and motivation of children with hearing loss in preschool and primary school based on their auditory perception levels. This study included 84 children with hearing loss aged 3-8 years and 50 normal-hearing children with similar demographic characteristics (the control group). The…

Familial risk for developmental dyslexia can compromise auditory and speech processing and subsequent language and literacy development. According to the phonological deficit theory, supporting phonological development during the sensitive infancy period could prevent or ameliorate future dyslexic symptoms. Music is an established method for…
