Confusion modelling for lip-reading
Lip-reading is mostly used as a means of communication by people with hearing di�fficulties. Recent work has explored the automation of this process, with the aim of building a speech recognition system entirely driven by lip movements. However, this work has so far produced poor results because of …

Lip Detection and Adaptive Tracking
… in these situations. This work proposes a lip detection and tracking algorithm to serve as a visual front end to an audio-visual automatic speech recognition (AVASR) system.</p> <p>Several color spaces are examined that are effective for segmenting lips from skin pixels. These color …

Decoding visemes: improving machine lip-reading
Abstract This thesis is about improving machine lip-reading, that is, the classi�cation of speech from only visual cues of a speaker. Machine lip-reading is a niche research problem in both areas of speech processing and computer vision. Current challenges for machine lip-reading fall into two …

Treatment profile for cleft lip and palate
… child in 600 live births is born with a cleft of lip, palate, or both structures. These deformities have a profound emotional effect both on parents and child and also seriously compromise physical and psychological wellbeing of the child affected with the deformity. Treatment procedures and …

Lip Profile Preferences in Varying Sagittal Mandibular Positions
… of sagittal mandibular position on preferred lip position in profile. Five androgynous silhouette profiles differing only in the degree of mandibular retro- or prognathism (-25º, -18º, -11º, -4º, & +3º facial contour angles) were created. Using a computer animation program, evaluators moved …

SPEECH DEVELOPMENT IN CHILDREN WITH CLEFT LIP AND PALATE
… of children with cleft palate and cleft lip and palate from pre-speech to the age of 4;6. The aim of the project was to investigate the extent to which the cleft palate condition affects the nature and chronology of phonetic and phonological development. The investigation comprised two …

Robust Unconstrained Face Detection and Lip Localization Using Gabor Filters
… (AVASR). A majority of AVASR research focuses on lip parameters extraction within controlled environments, but these scenarios fail to meet the demanding requirements of most real-world applications. Within the visual unconstrained environment, AVASR systems must compete with constantly changing …

IR-Depth Face Detection and Lip Localization Using Kinect V2
<p>Face recognition and lip localization are two main building blocks in the development of audio visual automatic speech recognition systems (AV-ASR). In many earlier works, face recognition and lip localization were conducted in uniform lighting conditions with simple backgrounds. However, such …

Gene Discovery In Nonsyndromic Cleft Lip With Or Without Cleft Palate
… </strong></p> <p> <p>Nonsyndromic cleft lip with or without cleft palate (NSCLP), a common, complex orofacial birth defect that affects approximately 4,000 newborns each year in the United States, is caused by both genetic and environmental factors. Orofacial clefts affect the mouth and …

Wearable lip-based electrotactile display : feasibility study, modeling, and system design
… the sense of touch, we proposed a wearable lip-based electrotactile display. The miniaturized display is most effective with lip interface due to the excellent sensory characteristics of lips. Since lips have never been utilized for tactile display applications, two human- subject …

Changes in Lip Position Coincident with the Movement of Artificial Teeth
… was devised and described to study changes in lip position coincident with the movement of artificial teeth. Investigation was initiated in an attempt to find out if when factors such as growth and occlusion are eliminated and if when factors such as centric relationship and vertical height of …

Early Academic Performance in Children with Cleft Lip and/or Palate.
… and language deficits in children with cleft lip and/or palate (CLP). For some children, the deficits during kindergarten diminish as they begin school while some children continue to show delays. The purpose of this study was to determine if a relationship exists between speech and language …

Beyond Lip Service: How teachers in a private school utilize multicultural literature
This qualitative dissertation is an investigation of the experiences of four middle grade teachers, three female and one male, three Caucasian and one African American who use multicultural literature in their language arts classrooms and the responses of the students of color they teach. The …

Exploration of Lip Shape Measures and their Association with Tongue Contact Patterns
… the vocal tract, specifically of the tongue and lips. In recent years, computer technology has allowed for extensive exploration of these precise movements and for the development of speech recognition systems. However, there has been relatively little work on the combination of visible facial …

The Impact of Surface Roughness on Transonic Inlet Lip-Flows at Incidence
… incidence, the flow-field around the lower inlet lip of a typical engine can accelerate to a supersonic value, creating a local supersonic region, terminated by a shock wave. This creates a shock wave-boundary-layer interaction, which could lead to detrimental consequences on the global …

Infrastructure development for integration of lip reading into the SUMMIT Speech Recognizer
… an audio-only speech recognizer with visual lip-reading information, in order to improve the performance and robustness of the recognizer. The speech recognizer's variable length audio segments are resolved with the fixed length video frames using segment constrained Hidden Markov Modeling. A …

Fzd6, Matn2 and Slc25A32, Possible Candidate Genes In Nonsyndromic Cleft Lip and Palate
<p>Nonsyndromic cleft lip with or without cleft palate (NSCLP) is a common birth defect with a multifactorial etiology. Despite decades of research, the genetic underpinnings of NSCLP still remain largely unexplained. A genome wide association study (GWAS) of a large NSCLP African American family …

Genetic Pathway Analysis of Abnormal Facial Development In Nonsyndromic Cleft Lip and Palate
<p>Nonsyndromic cleft lip with or without cleft palate (NSCLP) is the most common craniofacial birth defect resulting from incomplete fusion of the facial prominences during development, which leaves a gap in the lip, primary palate and/or the secondary palate. NSCLP affects 135,000 NSCLP newborns …
