Finding audiovisual material for reuse in new programs is an important activity for news producers, documentary makers, and other media professionals. Such professionals are typically served by an audiovisual broadcast archive. We report on a study of the transaction logs of one such archive. The analysis includes an investigation of commercial orders made by the media professionals and a chara...

Currently, detecting awareness in patients with disorders of consciousness (DOC) is a challenging task, which is commonly addressed through behavioral observation scales such as the JFK Coma Recovery Scale-Revised. Brain-computer interfaces (BCIs) provide an alternative approach to detect awareness in patients with DOC. However, these patients have a much lower capability of using BCIs compared...

Cochlear implants are neuroprostheses designed to restore speech perception in case of profound bilateral hearing loss. As speech is fundamentally an audiovisual percept, a deficit in processing auditory information might lead to changes in audiovisual integration of speech comprehension. Using vowel-consonant-vowel stimuli under unimodal, audiovisual congruent and audiovisual incongruent (McGu...

The article aims to test the hypothesis that audiovisual integration can improve spatial hearing in monaural conditions when interaural difference cues are not available. We trained one group of subjects with an audiovisual task, where a flash was presented in parallel with the sound and another group in an auditory task, where only sound from different spatial locations was presented. To check...

An increasing number of neuroscience papers capitalize on the assumption published in this journal that visual speech would be typically 150 ms ahead of auditory speech. It happens that the estimation of audiovisual asynchrony in the reference paper is valid only in very specific cases, for isolated consonant-vowel syllables or at the beginning of a speech utterance, in what we call "preparator...

In this paper I shall present a treatment of lexical and grammatical tone and vowel length in Hausa, as implemented in an emerging bidirectional HPSG of the language based on the Lingo Grammar Matrix (Bender et al., 2002). I shall argue in particular that a systematic treatment of suprasegmental phonology is indispensible in an implemented grammar of the language, both for theoretical and pract...

Speech is robustly audiovisual from early in infancy. Here we show that audiovisual speech perception in 4.5-month-old infants is influenced by sensorimotor information related to the lip movements they make while chewing or sucking. Experiment 1 consisted of a classic audiovisual matching procedure, in which two simultaneously displayed talking faces (visual [i] and [u]) were presented with a ...

The Role of Visuomotor Regulation Processes on Perceived Audiovisual Events Gerome Aleandro Manson Master of Science Graduate Department of Exercise Sciences University of Toronto 2013 Recent evidence suggests audiovisual perception changes as one engages in action. Specifically, if an audiovisual illusion comprised of 2 flashes and 1 beep is presented during the high velocity portion of upperl...

Speech perception can use not only auditory signals, but also visual information from seeing the speaker's mouth. The relative timing and relative location of auditory and visual inputs are both known to influence crossmodal integration psychologically, but previous imaging studies of audiovisual speech focused primarily on just temporal aspects. Here we used Positron Emission Tomography (PET) ...

one of the teachers involved in the Swinton experiment, recalls his reactions to the scheme. As one of the team of teachers in the implementation of this scheme my initial reaction was one of trepidation and dismay. With the single-minded view of the specialist, I felt that the pupils' acquisition of essential techniques and factual knowledge in my subject was to be sacrificed in the pursuit of...
