In this thesis, 3D animation of human facial expressions and lip motion and their synchronization with a Turkish Speech engine using JAVA programming language, JAVA3D API and Java Speech API, is analyzed. A three-dimensional animation model for simulating Turkish lip motion and facial expressions is developed. In addition to lip motion, synchronization with a Turkish speech engine is achieved. The output of the study is facial expressions and Turkish lip motion synchronized with Turkish speech, where the input is Turkish text in Java Speech Markup Language (JSML) format, also indicating expressions. The animation is created using JAVA3D API. 3D facial models corresponding to different lip positions of the same person are morphed to each other to construct the animation. Moreover, simulations of human facial expressions of emotions are created within the animation. Expression weight parameter, which states the weight of the given expression, is introduced. The synchronization of lip motion with Turkish speech is achieved via CloudGarden(R)'s Java Speech API interface [2]. "Levent16k SAPI 4-5 Male Voice" of G-V.S Voice Technologies Software Firm was used for Turkish speech engine [3]. As a final point a virtual Turkish speaker with facial expression of emotions is created for JAVA3D animation.
