Henry (and everyone else): It has to do with how development resources have been allocated in the respective companies (Dragon and MacSpeech). Dragon has had the benefit of having a codebase virtually unchanged since Windows 95. This has given them the last 11 years plus to improve their algorithms, add features, and just in general, tweak their software. MacSpeech, on the other hand, has had to rewrite our software from the ground up three times just to keep it running on the Mac: once to go from 68K to PPC, again to go from Mac OS 9 to Mac OS X, and just recently, yet again to go from PPC to Intel. We have our fingers crossed that Apple's "top secret" features for 10.5 will not require us to further retool our software in any substantial way. But the bottom line is that while Dragon has been able to significantly improve their training process, we have been mired in just keeping our software running on the platform. The good news is that all speech recognition software out there uses pretty much the same methodology: Hidden Markov Modeling. That's why you can eventually get accuracy from iListen on par with Dragon - it just takes longer to get there with iListen. Best Regards, Chuck Rogers, Chief Evangelist MacSpeech, Inc.
