In personal video communications, the postures assumed by the speaker during the connection are very similar. The speech of the person is strongly dependent on the assumed mouth positions. A convincing synthetic video animation can be obtained using precoded frames taken from the sequence, exploiting the redundancy between the mouth postures and the speech signal to "drive" a synthetic video of the speaker with negligible information added to the speech coding. This application can be considered as a simple realistic video flywheel to be used in very common congestion situation in IP based personal video communication applications. Convincing actions of the speaker to the receiving end user have been produced, basing on a video animation system. Preliminary results are presented.

Abstract
In personal video communications, the postures assumed by the speaker during the connection are very similar. The speech of the person is strongly dependent on the assumed mouth positions. A convincing synthetic video animation can be obtained using precoded frames taken from the sequence, exploiting the redundancy between the mouth postures and the speech signal to "drive" a synthetic video of the speaker with negligible information added to the speech coding. This application can be considered as a simple realistic video flywheel to be used in very common congestion situation in IP based personal video communication applications. Convincing actions of the speaker to the receiving end user have been produced, basing on a video animation system.
