Speech recognition requirements
To use speech recognition, you need the following hardware and software components:
A high-quality close-talk (headset) microphone. A Universal Serial Bus (USB) microphone is recommended.
A 400 megahertz (MHz) or faster computer with 128 megabytes (MB) of memory.
Microsoft Internet Explorer 5.0 or later.
The speech recognition engine must be installed. It is available with Microsoft Office XP, but might not have been installed. For more information, click Related Topics.
Speech recognition engines are language-specific. The first three Microsoft speech engines that are available are Simplified Chinese, U.S. English, and Japanese. Engines for other languages will become available.
