Talking heads - communication, articulation and animation
Jonas Beskow · 1996
Human speech communication relies not only on audition, but also on vision, especially during poor acoustic conditions. The face is an important carrier of both linguistic and extra-linguistic information. Using computer graphics it is possible to synthesize faces and do audio-visual text-to-speech synthesis, a technique that has a number of interesting applications for example in the area of man-machine interfaces. At KTH, a system for rule-based audio-visual text-tospeech synthesis has been developed. The system is based on the KTH text-tospeech system which has been complemented with a three-dimensional parametric model of a human face, that is animated in real time in synchrony with the auditory speech. The audio-visual text-to-speech synthesis has also been incorporated into a system for spoken man-machine dialogue.
