Introduction to Microsoft Agent
Microsoft Agent is a technology used to add interactive animated characters to Windows applications or Web pages. Microsoft Agent characters can speak and respond to user input via speech recognition and synthesis. Microsoft employs its Agent technology in applications such as Word, Excel and PowerPoint. Agents in these programs aid users in finding answers to questions and in understanding how the applications function.
The Microsoft Agent control provides programmers with access to four predefined characters-Genie (a genie), Merlin (a wizard), Peedy (a parrot) and Robby (a robot). Each character has a unique set of animations that programmers can use in their applications to illustrate different points and functions. For instance, the Peedy character-animation set includes different flying animations, which the programmer might use to move Peedy on the screen. Microsoft provides basic information on Agent technology at

Microsoft Agent technology enables users to interact with applications and Web pages through speech, the most natural form of human communication. To understand speech, the control uses a speech recognition engine-an application that translates vocal sound input from a microphone to language that the computer understands. The Microsoft Agent control also uses atext-to-speech engine, which generates characters' spoken responses. A text-to-speech engine is an application that translates typed words into audio sound that users hear through headphones or speakers connected to a computer. Microsoft provides speech recognition and text-to-speech engines for several languages at

Programmers can even create their own animated characters with the help of the Microsoft Agent Character Editor and the Microsoft Linguistic Sound Editing Tool. These products are available free for download from

This section introduces the basic capabilities of the Microsoft Agent control. For complete details on downloading this control, visit
