Experiments on Various Spatial-Temporal Features for Korean Lipreading
한국어 입술 독해에 적합한 시공간적 특징 추출
Abstract
Visual speech information improves the performance of speech recognition, especially in noisy environment. We have tested the various spatial-temporal features for the Korean lipreading and evaluated the performance by using a hidden Markov model based classifier. The results have shown that the direction as well as the magnitude of the movement of the lip contour over time is useful features for the lipreading.
