Purpose: Envelope following responses (EFRs) could be useful for objectively evaluating audibility of speech in children who are unable to participate in routine clinical tests. However, relative to adults, the characteristics of EFRs elicited by frequency-specific speech and their utility in predicting audibility in children are unknown. Method:…

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…

The process of perceiving music involves the transference of environmental physics in the air to anatomical and physiological interpretations of resonance in the body and psychological perceptions in the brain. These processes and musical interpretations are the basis of physical and cognitive science, neurophysiology, psychoacoustics, and…

Purpose: Processing real-world sounds requires acoustic and higher-order semantic information. We tested the theory that individuals with autism spectrum disorder (ASD) show enhanced processing of acoustic features and impaired processing of semantic information. Methods: We used a change deafness task that required detection of speech and…

The developmental trajectory of audiovisual speech perception in Mandarin-speaking children remains understudied. This cross-sectional study in Mandarin-speaking 3- to 4-year-old, 5- to 6-year-old, 7- to 8-year-old children, and adults from Xiamen, China (n = 87, 44 males) investigated this issue using the McGurk paradigm with three levels of…

Word identification accuracy is modulated by many factors including linguistic characteristics of words (frequent vs. infrequent), listening environment (noisy vs. quiet), and listener-related differences (older vs. younger). Nearly, all studies investigating these factors use high-familiarity words and noise signals that are either energetic…

This article proposes a conceptual and measurement framework for postpubertal, L2 speech learning aptitude that is centered around domain-general auditory processing (i.e., representing spectral and temporal characteristics of sounds). To this end, we examine the construct and reliability of a battery of auditory processing tests by presenting the…

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…
