Primary surgery of cleft lip and palate has dramatically improved with technical and material advances. Some adults who previously underwent surgery still have upper lip deformities or extensive scar, and they are occasionally seen for secondary treatment. We reported a case of unilateral cleft lip patient who had extensive scar involving the central 1/4 of the upper lip, with gross lip and nas...

________________________________________________________________________________________________________ Defining a motor perturbation paradigm for speech perception studies To display the role of motor knowledge in speech perception it may be necessary to attempt to modulate access to such knowledge during perception, in double tasks paradigms. But the motor task supposed to modulate perceptio...

The multimodal human-computer interface (HCI) called LipMouse is presented, allowing a user to work on a computer using movements and gestures made with his/her mouth only. Algorithms for lip movement tracking and lip gesture recognition are presented in details. User face images are captured with a standard webcam. Face detection is based on a cascade of boosted classifiers using Haar-like fea...

Lip contour extraction was a useful technique for obtaining a mouth shape in an image, and was one of the most important techniques for human-machine interface applications, such as lip reading and speech recognition. In this paper, a new method to extract lip contour from video was propose based on the fact that the lip color and skin-color was varied in the different color spaces. We first ex...

This paper proposes a unified statistical framework to synthesize speaking and laughing lip animations for virtual agents in real time. Our lip animation synthesis model takes as input the decomposition of a spoken text into phonemes as well as their duration. Our model can be used with synthesized speech. First, Gaussian mixture models (GMMs), called lip shape GMMs, are used to model the relat...

Current era is to make the interaction between humans and their artificial partners (Computers) and make communication easier and more reliable. One of the actual tasks is the use of vocal interaction. Speech recognition may be improved by visual information of human face. In literature, the lip shape and its movement are referred to as lip reading. Lip reading computing plays a vital role in a...

Within the communication process of human beings, the speaker’s facial expression and lip-shape movement contains extremely rich language information. The hearing impaired, aside from using residual listening to communicate with other people, can also use lip reading as a communication tool. As the hearing impaired learn the lip reading using a computer-assisted lip-reading system, they can fre...

When creating realistic talking head animations, accurate modeling of speech articulators is important for speech perceptibility. Previous lip modeling methods such as simple numerical lip modeling focus on creating a general lip model without incorporating lip speaker variations. Here we present a method for creating accurate speaker-specific lip representations that retain the individual char...
