Bring your media to life

The tasteful use of voice and animation can add a new dimension to your application or training material.

The Character Builder is a media authoring tool that installs on your PC and lets you generate unlimited, royalty-free materials in HTML5, Flash, video, and mobile formats.

Use it to create character animation for insertion into leading video and training tools, or to create web-ready modules that use talking avatars to present information, ask questions, and react to user input. You don't need to be an animator - all you need is a message.

For web developers, the optional Character Server generates audio and video streams from arbitrary text, and connects to leading Speech and AI software to power learning agents and digital assistants.

Discover plug-and-play animation

Pick a character, and create a script. Add actions such as Look, Point, and Show. Then watch as the software creates a smooth, natural delivery. The character can act like a puppet and deliver messages on cue, or it can run the whole show, complete with Powerpoint slides and interactive questions.

Most characters are available in head, bust, and body formats and are capable of speech, emotion, and gestures. Many can be customized using logos and swappable clothing. Some can even be made in your own likeness using a photo.

You can use your own voice, or that of a voice talent. Or save time with our high-quality Text-to-Speech addons.

Download the Character Builder

The Character Builder sets the standard for features, flexibility, and value. Use it alone, or with leading authoring tools, such as Adobe Captivate or After Effects.
