Microsoft Agent uses MIDI to play a tone when you press the Listening key. If you find that this interferes with other applications that play MIDI, you can turn off the Play Tone When You Can Speak option in the Microsoft Agent properties using the following procedure:
1. Load a page scripted for Microsoft Agent. When the Microsoft Agent icon appears in the taskbar, right-click it and choose Microsoft Agent Properties from the pop-up menu.
2. When the property sheet displays, select the Speech Input page.
3. Uncheck the Play Tone When You Can Speak option and click OK.
