Dragon Systems yesterday gave the first public showing of the Mac version of NaturallySpeaking, its voice-recognition software, at Comdex.

The software is yet to be perfected, and the company has not given a release date or set pricing for the Mac version - but the software’s continous-speech technology is functional.

During the Las Vegas Comdex demonstration, Dragon’s engineer, Adam Weiss, showed how the Mac-based word processor accurately reproduces spoken sentences. Voice commands can also be used to change font size and style. While the software does work with other applications, the formatting feature is restricted to the Dragon Systems word processor, the company told Macworld US.

Dragon has experienced developmental problems with the Mac version, including glitches with the way the Mac handles memory.

The Mac version, though, can open multiple documents - something beyond its Windows counterpart.
