BACKGROUND Hearing ability is essential for normal speech development, however the precise mechanisms linking auditory input and the improvement of speaking ability remain poorly understood. Auditory feedback during speech production is believed to play a critical role by providing the nervous system with information about speech outcomes that is used to learn and subsequently fine-tune speech ...

Auditory processing of speech is an important stage in the closed-loop human speech communication system. A computational auditory model for temporal processing of speech is described with details of numerical solution and of the temporal information extraction method given. The model is used to process fluent speech utterances and is applied to phonetic classification using both clean and nois...

In this paper, a method is proposed to evaluate contributions of auditory feedback to speech F0 trajectory generation. This method is based on data obtained in a series of new auditory feedback experiments (TAF: transformed auditory feedback) in which quantitative measurements were taken of interactions between speech perception and production under natural speech conditions. Experimental resul...

While neurocognitive data provide clear evidence for the involvement of the motor system in speech perception, its precise role and the way motor information is involved in perceptual decision remain unclear. In this paper, we discuss some recent experimental results in light of COSMO, a Bayesian perceptuo-motor model of speech communication. COSMO enables us to model both speech perception and...

Objective: The aim of the present research was to compare the auditory perception and verbal intelligibility in children with cochlear implant, hearing aids and normal hearing. Methods: 60 children aged 5-7 years were divided to three groups and each group contained 20 children. The first and second groups were selected ordinarily from children with cochlear implant and hearing aids by conve...

A computer-implemented neurofunctional model of speech production is introduced, which is capable of articulating vowels, VC-, and CV-syllables (C = voiced plosives; V = vowels). It will be shown in this paper that this production model is capable of simulating basic effects of auditory and audio-visual speech perception like (i) categorical perception of consonants and vowels and (ii) the McGu...

Speech perception is known to rely on both auditory and visual information. However, sound-specific somatosensory input has been shown also to influence speech perceptual processing (Ito et al., 2009). In the present study, we addressed further the relationship between somatosensory information and speech perceptual processing by addressing the hypothesis that the temporal relationship between ...

Speech researchers have long been interested in how auditory and visual speech signals are integrated, and the recent work has revived interest in the role of speech production with respect to this process. Here, we discuss these issues from a developmental perspective. Because speech perception abilities typically outstrip speech production abilities in infancy and childhood, it is unclear how...

But the motor task supposed to modulate perceptio...
