A recent letter to the journal Nature claimed integration of auditory and tactile information in speech perception. Although multisensory integration of auditory and visible speech has been repeatedly documented, neither perception nor integration was sufficiently formalized, operationalized, and tested to support this claim about auditory and tactile information. In a recent letter to the jour...

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...

As people age, speech perception problems become highly prevalent, especially in noisy situations. In addition to peripheral hearing and cognition, temporal processing plays a key role in speech perception. Temporal processing of speech features is mediated by synchronized activity of neural oscillations in the central auditory system. Previous studies indicate that both the degree and hemisphe...

Effects of auditory training with bimodal audio-visual stimuli on monomodal aural speech intelligibility were examined in individuals with normal hearing using highly degraded noise-vocoded speech sound. Visual cue simultaneously presented with auditory stimuli during the training session significantly improved auditory speech intelligibility not only for words used in the training session, but...

A theory of speech perception that maps between auditory input and articulatory features was most famously proposed by Liberman et al. (1967). Their theory was later revised by the same authors (Liberman & Mattingly, 1985) to account for new discoveries in comparative evolutionary biology and developmental psychology. Although not the first to propose that gestural features were the fundamental...

OBJECTIVE We compared intracranial recordings of auditory event-related responses with electrocortical stimulation mapping (ESM) to determine their functional relationship. METHODS Intracranial recordings and ESM were performed, using speech and tones, in adult epilepsy patients with subdural electrodes implanted over lateral left cortex. Evoked N1 responses and induced spectral power changes...

Speech perception, especially in noise, may be maximized if the perceiver observes the naturally occurring visual-plus-auditory cues inherent in the production of spoken language. Evidence is conflicting, however, about which aspects of visual information mediate enhanced speech perception in noise. For this reason, we investigated the relative contributions of audibility and the type of visual...
