FlashSpec is a stand-alone application that produces synchronization data specifically for use with Flash. It allows you to control animations and other events in Flash using amplitude or spectrum (frequency) values derived from sound files. It works as a Winamp plugin and thus requires winamp to be installed to work correctly. This allows it to support all audio formats that are supported by winamp, which is a long list.
Alf is a highly-customizable flash character which you can put on any website. It accepts input from the keyboard and responds in a human voice (optionally your own) with seamless lip synchronization.

Alf can be Jessica the saleslady, Ronald the teacher, Cathy the site guide, Erwin the troubadour or any other implementation you can think of.
