“…First, while WiN performance in children with ASD showed some developmental improvement throughout childhood, neither child's age nor IQ could explain correlations between the reduced SPN and lowered WiNam scores (Table 2). The lack of correlation between WiN scores and IQ agrees well with the previous findings on the presence of speech-in-noise recognition difficulties even in high-functioning individuals with ASD [4]. On the other hand, our results suggest that these problems may be caused, at least in part, by a deficient vowel processing in the cortical networkс.…”

“…Most individuals with ASD have delayed early language development, and deficits in receptive and expressive language present to some degree in the majority of children with ASD [2,3]. A common difficulty faced by people with ASD, even those with normal or above normal IQ, is a poor listening ability under suboptimal acoustic conditions, both in experimental settings (for a review see [4]) and in real-life [5].…”

“…We next asked whether atypical vowel processing is associated with impairment in the ability of children with ASD to distinguish speech from background noise. Such a possibility is worth investigating given the psychoacoustic evidence for the importance of vowels for speech intelligibility [36] and the evidence for impaired speech-in-noise recognition in ASD individuals with normal-range IQ and audiometrically normal hearing (for a review see [4]).…”

BackgroundDifficulties with speech-in-noise perception in autism spectrum disorders (ASD) may be associated with impaired analysis of speech sounds, such as vowels, which represent the fundamental phoneme constituents of human speech. Vowels elicit early (< 100 ms) sustained processing negativity (SPN) in the auditory cortex that reflects the detection of an acoustic pattern based on the presence of formant structure and/or periodic envelope information (f0) and its transformation into an auditory ‘object’.MethodsWe used magnetoencephalography (MEG) and individual brain models to investigate whether SPN is altered in children with ASD and whether this deficit is associated with impairment in their ability to perceive speech in the background of noise. MEG was recorded while boys with ASD and typically developing boys passively listened to sounds that differed in the presence/absence of f0periodicity and formant structure. Word-in-noise perception was assessed in the separate psychoacoustic experiment using stationary and amplitude modulated noise with varying signal-to-noise ratio.ResultsSPN was present in both groups with similarly early onset. In children with ASD, SPN associated with processing formant structure was reduced predominantly in the cortical areas lateral to and medial to the primary auditory cortex, starting at ∼ 150 - 200 ms after the stimulus onset. In the left hemisphere, this deficit correlated with impaired ability of children with ASD to recognize words in amplitude-modulated noise, but not in stationary noise.LimitationsOur analysis was limited to the auditory cortical areas, while ASD vs TD differences in vowel processing may exist beyond these areas. It is not clear if the SPN group differences are specific to vowels or are also present for other acoustic patterns with coherent frequency structure.ConclusionsThese results suggest that perceptual grouping of vowel formants into phonemes is impaired in children with ASD and that, in the left hemisphere, this deficit contributes to their difficulties with speech perception in fluctuating background noise.

“…In a study of basic psychoacoustic abilities, Jones et al (2009) reported a subset (20%) of autistic people to possess "excellent" abilities to distinguish different sound frequencies from each other, and that these abilities were unrelated to overall sensitivity to sound (i.e., hearing thresholds), whilst those who performed poorly on an intensity-discrimination task reported more behaviors reflective of discomfort to sound stimulation. In contrast, autistic people who performed well on distinguishing between different durations of sounds reported greater auditory sensory behaviors (Ruiz Callejo et al, 2023). The authors suggested that the range of auditory discrimination skills evident in autism may impact auditory sensory behaviors by altering the degree to which environmental noises are detected or overlooked (Jones et al, 2009).…”

Interpreting the world around us requires integrating sensory information across modalities to derive meaning and shape our experiences and interactions with and within everyday environments. Recent interest in sensory-focused approaches to supporting autistic people has fixed on auditory processing—the sense of hearing and the act of listening—and its crucial role in language, communications, and social domains, as well as non-social autism- specific attributes, to understand better how sensory processing might differ in autistic people. In this narrative review, we synthesize published research into auditory processing in autistic people and the relationship between auditory processing and autistic attributes in a contextually novel way. The purpose is to understand the relationship between these domains more fully, drawing on evidence gleaned from experiential perspectives through neurological investigations. We also examine the relationship between auditory processing and diagnosable auditory conditions, such as hyperacusis, misophonia, phonophobia, and intolerance to loud sounds, as well as its relation to sleep, anxiety, and sensory overload. Our review reveals that autistic people often exhibit differences in their auditory profile early in life and that this intrinsically impacts their neurological development and shapes their broader autistic profile. Through a better understanding of the potential impact of auditory experiences on daily life, our review aims to inform future research on how to support the auditory profile of autistic people through accessible environments and improved strategies, technologies, and strategies for supporting autistic people in everyday life.

We need to combine sensory data from various sources to make sense of the world around us. This sensory data helps us understand our surroundings, influencing our experiences and interactions within our everyday environments. Recent interest in sensory‐focused approaches to supporting autistic people has fixed on auditory processing—the sense of hearing and the act of listening—and its crucial role in language, communications, and social domains, as well as non‐social autism‐specific attributes, to understand better how sensory processing might differ in autistic people. In this narrative review, we synthesize published research into auditory processing in autistic people and the relationship between auditory processing and autistic attributes in a contextually novel way. The purpose is to understand the relationship between these domains more fully, drawing on evidence gleaned from experiential perspectives through to neurological investigations. We also examine the relationship between auditory processing and diagnosable auditory conditions, such as hyperacusis, misophonia, phonophobia, and intolerance to loud sounds, as well as its relation to sleep, anxiety, and sensory overload. Through reviewing experiential, behavioral and neurological literature, we demonstrate that auditory processes interact with and shape the broader autistic profile—something not previously considered. Through a better understanding of the potential impact of auditory experiences, our review aims to inform future research on investigating the relationship between auditory processing and autistic traits through quantitative measures or using qualitative experiential inquiry to examine this relationship more holistically.
