If you have difficulty running Microsoft Agent on your machine, please refer to the following list of symptoms and try the suggested steps to isolate and solve the problem. If these suggestions don't resolve the problem, let us know by sending us a bug report.
Page Loading or Installation Problems
When I attempt to load a page scripted for Microsoft Agent, nothing happens.
How do I remove Microsoft Agent from my system?
Does Microsoft Agent work in Internet Explorer 4.0?
Speech Input Problems
The character does not respond to voice commands that I used to train it.
The character does not respond to voice commands on a sample page.
The character does not respond to my voice input.
This usually occurs when you don't have Microsoft Agent or some other control that page uses installed, and choose No when you are prompted to install the control. Try refreshing the page, though the page may work only if you install all the components it requires.
Because Microsoft Agent writes files to your system directory when it installs, you must have administrator (not user) privileges to install.
Installation of Microsoft Agent requires Regsvr32.exe (and other OLE dlls) being properly installed. The best way to ensure that all the correct system files are present is to install Microsoft Internet Explorer 3.02 or later.
Microsoft Agent is implemented using ActiveX interfaces. You can use it only with a browser (such as Microsoft Internet Explorer) that supports embedding ActiveX objects through script on a page, and only on systems running Microsoft Windows 95 and Windows NT 4.0. If you are not using Microsoft Internet Explorer, check with your browser vendor for further information on ActiveX support.
To uninstall Microsoft Agent, open the Control Panel, then open the Add/Remove Programs object. You should find Microsoft Agent included in the list. Select the entry, then click the Add/Remove button.
The Microsoft Agent uninstall utility removes only the Microsoft Agent services. If you also installed the Lernout & Hauspie® TruVoice Text-To-Speech Engine for Microsoft Agent, select this and click the Add/Remove button. In addition, if you also installed Microsoft Command and Control speech engine and you know that no other application uses it, you should select and remove the following entries:
Microsoft Command and Control EngineMicrosoft Speech Lexicon
Microsoft Speech API (3.0)
Does Microsoft Agent work in Internet Explorer 4.0?
Please note that Microsoft Agent will not run in Internet Explorer 4.0 Platform Preview, due to a bug in the Internet Explorer 4.0 Preview version. This should be corrected in the next beta release of Internet Explorer 4.0, which will be released soon. Until then we recommend that you use IE 3.02 for accessing Microsoft Agent.
Voice training does not teach the character new commands. It does help the speech engine better recognize your voice input. The only way to teach the character new commands is to define voice commands as part of your Web page (application). Consult Programming the Microsoft Agent Control for further information on how to do this.
Not all sample pages support speech input. The Goodbye World sample on this site's sample page does (click the HTML Sample Pages link in the left pane to see the Goodbye World sample). To speak to the character, press and hold the Scroll Lock key. If the character does not respond to any of these commands, check the following sections on troubleshooting voice input for additional recommendations.
This symptom may be caused by a number of problems. Try the following to isolate the problem:
The best way to do this is to run the Sound Recorder application that comes with Windows. It can usually be found on the Start menu. Click the Start button, then Programs, then Accessories, then Multimedia, and then Sound Recorder. When the Sound Recorder window displays, click the Record button and talk into your microphone. The line in the window should animate in response to your voice input.If the Sound Recorder application doesn't work on your system, contact the sound card manufacturer's technical support department for assistance. Your sound card may not be compatible with Windows or there may be a problem with the software drivers for your sound card.
- Load a page scripted for Microsoft Agent. When the character appears, right-click on it and choose Microsoft Agent Properties from the pop-up menu.
- When the property sheet displays, select the Speech Input page.
- Choose the Adjust Microphone button. If this button appears disabled, a compatible speech engine is not installed or the speech engine you installed may not support automatic adjustment.
Your sound card is not set up properly for use with Microsoft Agent. Choose the Adjust Microphone options on the Speech Input page of the Microsoft Agent property sheet. See the previous section for information on how to access this button.
