What is "Microsoft Agent"? Microsoft® Agent is a set of programmable software services that supports the presentation of interactive animated characters within Microsoft Windows. Web Developers can use these characters as interactive assistants to introduce, guide, entertain, or otherwise enhance their Web pages. They can even be used in applications. Microsoft Agent enables software developers and Web authors to incorporate a new form of user interaction, known as conversational interfaces, that leverages natural aspects of human social communication. In addition to mouse and keyboard input, Microsoft Agent includes optional support for speech recognition so applications can respond to voice commands. Characters can respond using synthesized speech, recorded audio, or text in a cartoon word balloon.
