  • We receive a lot of our speech information via visual cues, such as lip-reading, and this type of visual speech occurs throughout all cultures. And it is not just information from lips- when someone is speaking to us, we will also note movements of the teeth, tongue and other non-mouth facial features. It's likely that human speech perception has evolved to integrate many senses together. Put in another way, speech is not meant to be just heard, but also to be seen.
  • Recent studies indicate that this integration occurs very early in the speech process, even before phonemes (the basic units of speech) are established. Rosenblum suggests that physical movement of speech (that is, our mouths and lips moving) create acoustic and visual signals which have a similar form. He argues that as far as the speech brain is concerned, the auditory and visual information are never really separate. This could explain why we integrate speech so readily and in such a way that the audio and visual speech signals become indistinguishable from one another.

  Une étude qui tend à montrer que lorsque quelqu'un parle il n'y a pas que notre sens de l'ouïe qui est sollicité mais aussi celui de la vue.

  • We tend to think of speech as being something we hear, but recent studies suggest that we use a variety of senses for speech perception - that the brain treats speech as something we hear, see and even feel.
