We present a method to generate mouth animations coupled with moderate movements of the head. Our method uses a coarse 2D textured mesh representation of images. With hardware texture mapping, we obtain 30 frames/sec animations on modest PC platforms. The synthesized animation sequence is realistic and lively. Radial basis functions are used in the underlying animation engine. At each phoneme t...

Reverberation-robust speech recognition has become very important in the recognition of distant-talking speech. However, as no common reverberation criteria for the recognition of reverberantspeech have been proposed, it has been difficult to estimate this. We have thus focused on a reverberation criterion for the recognition of distant-talking speech. The reverberation time is generally curren...

Usually, people talk neutrally in environments where there are no abnormal talking conditions such as stress and emotion. Other emotional conditions that might affect people talking tone like happiness, anger, and sadness. Such emotions are directly affected by the patient health status. In neutral talking environments, speakers can be easily verified, however, in emotional talking environments...
