“…Alternatively, the ASD-HIGH children may register the stimulus appropriately, but because they have relatively poor control over their vocal system, the result is a very large change in voice F 0 . Regardless of sensitivity, abnormal auditory pathway function in general may be responsible for disrupted input into the initial stage of the auditory vocal motor system (Erwin et al 1991;McClelland et al 1992;Klin 1993;Maziade et al 2000;Wang et al 2001;Boddaert et al 2003;Ceponiene et al 2003;Jansson-Verkasalo et al 2003;Rapin and Dunn 2003;Rosenhall et al 2003;Boddaert et al 2004;Gervais et al 2004;Kasai et al 2005;Kujala et al 2005;Lepisto et al 2005Lepisto et al , 2006Korpilahti et al 2006;Tharpe et al 2006). All of these possibilities warrant further study.…”

“…In one study investigating brainstem transcription of F 0 contour in speech in children with ASD, deficient pitch tracking was identified in only a subset of those children, while brainstem function was normal in the other children with ASD (Russo et al 2008 in press). Further, there is ample evidence for deficient or atypical cortical processing of speech or speech-like stimuli associated with ASD (Wang et al 2001;Boddaert et al 2003Boddaert et al , 2004Ceponiene et al 2003;Jansson-Verkasalo et al 2003;Gervais et al 2004;Kasai et al 2005;Lepisto et al 2005Lepisto et al , 2006, including reports of deficient cortical processing specific to prosody (Erwin et al 1991;Wang et al 2001;Kujala et al 2005;Korpilahti et al 2006). Even amidst these recent findings, much of the physiology behind the language impairment and characteristic speech production patterns in ASD is still unmapped.…”

Audio–vocal system regulation in children with autism spectrum disorders

Do children with autism spectrum disorders (ASD) respond similarly to perturbations in auditory feedback as typically developing (TD) children? Presentation of pitch-shifted voice auditory feedback to vocalizing participants reveals a close coupling between the processing of auditory feedback and vocal motor control. This paradigm was used to test the hypothesis that abnormalities in the audio-vocal system would negatively impact ASD compensatory responses to perturbed auditory feedback. Voice fundamental frequency (F 0 ) was measured while children produced an /a/ sound into a microphone. The voice signal was fed back to the subjects in real time through headphones. During production, the feedback was pitch shifted (-100 cents, 200 ms) at random intervals for 80 trials. Averaged voice F 0 responses to pitch-shifted stimuli were calculated and correlated with both mental and language abilities as tested via standardized tests. A subset of children with ASD produced larger responses to perturbed auditory feedback than TD children, while the other children with ASD produced significantly lower response magnitudes. Furthermore, robust relationships between language ability, response magnitude and time of peak magnitude were identified. Because auditory feedback helps to stabilize voice F 0 (a major acoustic cue of prosody) and individuals with ASD have problems with prosody, this study identified potential mechanisms of dysfunction in the audio-vocal system for voice pitch regulation in some children with ASD. Objectively quantifying this deficit may inform both the assessment of a subgroup of ASD children with prosody deficits, as well as remediation strategies that incorporate pitch training.

“…Relevant is also the increased prevalence of absolute pitch and musical savants in the ASD population (e.g., DePape et al 2012;Heaton et al 2008a, b, c;Miller 1989;Mottron et al 2013) and the increased prevalence of autistic traits among possessors of absolute pitch (e.g., Dohn et al 2012). The occurrence of this superior pitch processing contrasts with the inferior temporal processing abilities in ASD (such as impaired gap-in-noise detection, duration discrimination, temporalenvelope processing, temporal order judgement; e.g., Alcántara et al 2012;Bhatara et al 2013;Kwakye et al 2011;Lepisto et al 2005Lepisto et al , 2006Samson et al 2011; but see Jones et al 2009;Kasai et al 2005) and the evidence of speech perception impairments (Alcántara et al 2004;Bhatara et al 2013;Groen et al 2009) and generally delayed speech and language development (e.g., Anderson et al 2007). Speech perception has been shown to be particularly impaired while presented in noise with temporal dips (Alcántara et al 2004;Groen et al 2009) or in a competing talker condition (Alcántara et al 2004;Bhatara et al 2013).…”

Fragile Spectral and Temporal Auditory Processing in Adolescents with Autism Spectrum Disorder and Early Language Delay

We investigated low-level auditory spectral and temporal processing in adolescents with autism spectrum disorder (ASD) and early language delay compared to matched typically developing controls. Auditory measures were designed to target right versus left auditory cortex processing (i.e. frequency discrimination and slow amplitude modulation (AM) detection versus gap-in-noise detection and faster AM detection), and to pinpoint the task and stimulus characteristics underlying putative superior spectral processing in ASD. We observed impaired frequency discrimination in the ASD group and suggestive evidence of poorer temporal resolution as indexed by gapin-noise detection thresholds. These findings question the evidence of enhanced spectral sensitivity in ASD and do not support the hypothesis of superior right and inferior left hemispheric auditory processing in ASD.
