IBM ViaVoice Toolkit for Animation provides data files and a modified speech recognition engine that allows the ViaVoice dictation product to send phonetic and audio information to a client process to be used for synchronizing character mouth movement with the corresponding speech. In addition, it includes the header files neccesary for building a client as well as sample code and images for creating real-time or offline lip sync animations.
This technology opens the possibility for live animation of speaking characters and provides simple and accurate lip sync for scripted animation, bringing character dialog animation within reach of nonprofessionals.
The toolkit includes sample code that generates real-time Macromedia Flash animations. Software developers can use this example to help them integrate the technology into their animation systems. With IBM ViaVoice for Windows R10 and this toolkit, developers have everything necessary for adding automatic lip sync capability to their animation systems
