Department of Linguistics and Languages will host a talk by Dr. Lucie Menard from UQAM on March 8, 2017. This is part of the Cognitive Science of Language lecture series of the current academic year. In face-to-face conversation, speech is produced and perceived through various modalities. Movements of the lips, jaw, and tongue, for instance, modulate air pressure to produce a complex waveform perceived by the listener’s ears. Visually salient articulatory movements (of the lips and jaw) also contribute to speech identification. Although many studies have been conducted on the role of visual components in speech perception, much less is known about their role in speech production. However, many studies have emphasized the important relationship between speech production and speech perception systems. If, as suggested by many researchers, perceived visual and auditory cues are not independent but instead act in synergy and complement each other, they must be involved in the speech production process. In this talk. Dr. Menard will explore the effects of auditory and visual feedback on speech production.
