Abstract(in English) | We propose a large vocabulary sign language recognition method. While most conventional methods used word units for sign language modeling, it is difficult to apply such methods to large-vocabulary recognition. Inspired by the use of phoneme units in speech recognition, we introduce "chereme" unit models in large-vocabulary sign language recognition. The problems are how to define cheremes and developing a recognition algorithm using cheremes. We first represent signs using the 6 elements: "hand movement-hold", "hand shape" and "wrist direction" of both hands. Then, we define chereme unit HMMs in each element. We use the weighted sum of output probabilities of the HMMs of these elements for recognition. We evaluated our method by using isolated sign language recognition. We achieved 78.2% word correct on the closed set of 258 words and 23.6% word correct on the open set with 469 words. We also achieved 18.8% word correct on speaker-independent recognition. |
