A visual speech synthesis approach using Chinese visual triphone is presented. According to Mandarin Chinese pronunciation principle and the relationship between phoneme and viseme, “Chinese visual triphone” model is constructed. Triphone hidden Markov model is established based on visual triphones. Joint features composed of visual features and audio features are used in the training stage. In the...
In area environment, variations of life form can exhale difference kind of audio signals, and these audio signals are nearly correlative with different biologic subsistence conditions and human activities. To analyze these audio signals automatically, in this paper, we propose a method, which employ effective segment length of audio data (ESLOAD), frequency component of maximum harmonic weight (FCOMHW)...
A target tracking is an important embranchment of WSN, which can assure the position of a moving target real-time. This paper works on the prediction problem of target tracking of chain-type wireless sensor networks. We choose RBF neural network as the basis of the tracking prediction model. Based on analysis of chain-type tracking characters and RBF neural network based tracking prediction model,...
In this work a tele-operated system for a robot arm is designed and controlled by the operator, in witch voice control mode occur to carry out remote tasks. A voice command system for the manipulator arm is implemented as a high level control design and compared to a low level control design based on joystick. The high level control paradigm adopted is based on a spotted words recognition system using...
