This paper presents an initial bimodal acoustic-visual synthesis system able to generate concurrently the speech signal and a 3D animation of the speaker's face. This is done by concatenating bimodal diphone units that consist of both acoustic and visual information. The latter is acquired using a stereovision technique. The proposed method addresses the problems of asyn- chrony and incoherence inherent in classic approaches to audiovisual synthesis. Unit selection is based on classic target and join costs from acoustic-only synthesis, which are augmented with a visual join cost. Preliminary results indicate the benefits of this approach, since both the synthesized speech signal and the face animation are of good quality.
