I have created a poc component (named it as “MobileWish LipSyncAS3”) for dynamic lip sync using ActionScript 3 in Flash CS3. This beta version matches the lip sync from any of the supplied MP3 file containing pure speech. This can be handy tool for adding lip sync for flash characters in any dynamic interactive. I had been using third party tools like Flash Amp for lip sync in some of my previous projects. But that involved pre processing of audio mp3 files for creating amplitude value. Now with AS3 there is no need to preprocess the mp3 files, rather the lip sync will be instantly done on the run time which will be an added advantage.
Given below is the sample video of my working prototype at Youtube.
I will finetune it and will soon be uploading it to MobileWish website (www.mobilewish.com)
