“…During the auditory perception of speech, the central hearing has to process complex acoustic structures in real-time. Adequate processing of acoustic information is the requirement for speech and language development [ 1 ]. Particularly, disorders in the temporal processing are supposed to be responsible for deficient auditory discrimination abilities, which can result in an impaired speech perception [ 2 ].…”

We examined the neural activation to consonant-vowel transitions by cortical auditory evoked potentials (AEPs). The aim was to show whether cortical response patterns to speech stimuli contain components due to one of the temporal features, the voice-onset time (VOT). In seven normal-hearing adults, the cortical responses to four different monosyllabic words were opposed to the cortical responses to noise stimuli with the same temporal envelope as the speech stimuli. Significant hemispheric asymmetries were found for speech but not in noise evoked potentials. The difference signals between the AEPs to speech and corresponding noise stimuli revealed a significant negative component, which correlated with the VOT. The hemispheric asymmetries can be referred to rapid spectral changes. The correlation with the VOT indicates that the significant component in the difference signal reflects the perception of the acoustic change within the consonant-vowel transition. Thus, at the level of automatic processing, the characteristics of speech evoked potentials appear to be determined primarily by temporal aspects of the eliciting stimuli.

“…Although there has been a wide range of narrative reviews considering the effectiveness of speech and language interventions (Snyder‐McLean & McLean, 1987; Guralnick, 1988; Goldstein & Hockenburger, 1991; McLean & Woods Cripe, 1997; Gallagher, 1998; Leonard, 1998; Olswang, 1998) there have, to date, been only two systematic reviews of the literature (Nye, Foster, & Seaman, 1987; Law et al, 1998). In early 2003 a third systematic review and meta‐analysis was completed for the Cochrane Collaboration and the Campbell Collaboration (Law, Garrett, & Nye, 2003).…”

This review examines the implications of a recent systematic review of speech and language therapy interventions for child mental health services. The premise is that communication skills and mental health are closely related and that intervention in the one field may have an impact on skills and achievement in the other. The paper begins by discussing what we know about the relationship between speech/language and behavioural difficulties; it then reports results from the review, before examining the implications for practice and policy.

“…During auditory perception of speech, the central auditory processing system has to process complex acoustic stimuli in real time. For speech and language development, good processing of complex acoustic stimuli is important [6]. Temporal processing ability, in particular, has a major role in speech perception.…”

Background: Previous studies have used the acoustic change complex (ACC) as a tool to investigate the perception of acoustic changes in an ongoing signal in various populations. However, there is no study that has explored the usefulness of ACC to objectively study the neural representation of CV transition in children with CAPD. The present study aims to investigate the utility of ACC as an objective tool to study neural representation of a CV transition in children with CAPD.Material and methods: There were 40 children aged 8 to 14 years in this study. They were divided into 2 groups of 20 children each based on the outcomes of audiological tests: a clinical group (CAPD) and a comparison group. A diagnosis of CAPD was made for 20 children after completion of a two-stage evaluation process (screening and diagnosis). The ACC was acquired using Neuro Scan Syn (v. 4.4) for the naturally produced CV stimulus /sa/ which had a total duration of 380 ms.Results: A Mann-Whitney U-test revealed significantly delayed latency of N1′ and P2′ in children with CAPD compared to healthy children. However, there was no significant difference in peak-to-peak amplitude of N1′-P2′ between children with CAPD and normal children. Conclusions:The prolonged latencies of ACC indicated poor encoding of the CV transition in children with CAPD. It is suggested that poor temporal processing of CV transitions in these children might be the reason for poor speech perception in the CAPD population.
