In conversational settings, one sees as much as one hears the interlocutor. Compelling demonstrations of auditory-visual integration in speech perception are the classic McGurk effects [1]: in McGurk “fusion,” an auditory [p] dubbed onto a face articulating [k] is perceived as a single fused percept [t], but in McGurk “combination,” an auditory [k] dubbed onto a visual [p] is heard as multiple ...

We discuss a 3D spatial analysis of fMRI data taken during a combined word perception and motor task. The event based experiment was part of a study to investigate the network of neurons involved in the perception of speech and the decoding of auditory speech stimuli. We show that a classical general linear model analysis using SPM does not yield reasonable results. With blind source separation...

Introduction: Auditory temporal resolution and auditory temporal ordering are two major components of the auditory temporal processing abilities that contribute to speech perception and language development. Auditory temporal resolution and auditory temporal ordering can be evaluated by gap-in-noise (GIN) and pitch-pattern-sequence (PPS) tests, respectively. In this survey, the effect of biling...

Interactions between auditory and somatosensory information are relevant to the neural processing of speech since speech processes and certainly speech production involves both auditory information and inputs that arise from the muscles and tissues of the vocal tract. We previously demonstrated that somatosensory inputs associated with facial skin deformation alter the perceptual processing of ...

Speech reading enhances auditory perception in noise. One means by which this perceptual facilitation comes about is through information from visual networks reinforcing the encoding of the congruent speech signal by ignoring interfering acoustic signals. We tested this hypothesis neurophysiologically by acquiring EEG while individuals listened to words with a fixed portion of each word replace...

We studied the modification of auditory perception in three different conditions in twenty subjects. Observing other person's discordant articulatory gestures deteriorated identification of acoustic speech stimuli and modified the auditory percept, causing a strong McGurk effect. A similar effect was found when the subjects watched their own silent articulation in a mirror and acoustic stimuli ...

BACKGROUND The use of cochlear implant results in the optimization of speech perception, and, as a consequence in the development of oral language, speech and voice of its users, demonstrating to be one of the most effective and promising technologies to remedy hearing loss. However, little has been studied about the relationship between auditory skills and the voice of children using cochlear ...

There is a growing consensus that developmental dyslexia is associated with a phonological-core deficit. One symptom of this phonological deficit is a subtle speech-perception deficit. The auditory basis of this deficit is still hotly debated. If people with dyslexia, however, do not have an auditory deficit and perceive the underlying acoustic dimensions of speech as well as people who read no...

We used Auditory/visual masks to investigate how the availability of speech signals governs speech perception. Stimuli were videos of a talker uttering sentences. The auditory mask consisted of speech shaped noise; the visual mask, a circular patch obscuring talker’s mouth region. Auditory signals were quantified by the glimpse proportion (GP); visual signals by visual entropy (VE), a measure b...

The functional neuroanatomy of speech perception has been difficult to characterize. Part of the difficulty, we suggest, stems from the fact that the neural systems supporting 'speech perception' vary as a function of the task. Specifically, the set of cognitive and neural systems involved in performing traditional laboratory speech perception tasks, such as syllable discrimination or identific...
