Usable Speech Recognition

The following is a sidebar accompanying an article published by Directions on Microsoft, an independent research firm focused exclusively on Microsoft strategy & technology. More samples of our content, as well as a list of upcoming articles and reports are also available.

The following table compares the results of reading a passage into different versions of Windows and having the text sent to the current supported version of Microsoft Word. The same passage from the first test in 2001 was repeated with Vista, although due to space limitations, only a representative portion of the results is reproduced here. Bold shows where recognition failed and the text had to be manually corrected.

The computer running Windows XP (2001) was a Toshiba Satellite with a Pentium III processor and 512 MB of RAM. The desktop computer running Vista RC1 is a Dell Precision 450 with a Xeon processor and 1 GB of RAM. The mobile computer running Windows Vista RC1 is an Acer TravelMate 200C with a Centrino processor and 512 MB of RAM. Since all tests were done with the same microphone (headset), ambient noise, and pretest training of the software, the availability of computer processing power appears to factor into the successful interpretation of speech.

For many years I have hoped that speech recognition would make it easier for me to work with my computer. Several years ago when I purchased and I'm back computeran iMac computer I found the speech recognition program for the buybackiMac. (At this point, Cherry entered the word "iMac" into the speech recognition program with his pronunciation.) While the program cost only 49 dollars I had hoped that the program would allow me to dig take Dick K. T. dictate specifications, technical documents, and white papers, making me more productive as a program manager. For many years I have hoped that speech recognition would make it easier for me to work with my computer. Several years ago when I purchased an Yi Mac iMac (At this point, Cherry used speech recognition to spell iMac) computer I found the speech recognition program for the imac. While the program cost only $49.00 I had hoped that the program would allow me to dictate specifications, technical documents, and white papers, making me more productive as a program manager. For many years by default if the recognition would make it easier for me were with one another so avoid years ago when I purchased and on Mac Computer life of the speech recognition program for the automat while the program cost: $49.00 I hope that the program will allow me to play specifications, technical documents, and why favor, making me a more productive farmland then.

(Due to the high error rate, this test was abandoned at this point.)
Despite training the program for several hours including reading most of tTreasure iIsland to my computer I found that the program was unable to make me more productive. Technical words, application programming interfaces, jargon, and code names such as many tests mantis, would come out as anything but the word mantis was just too frustrating.

Needless to say I did not hold out much hope for speech recognition contained in Microsoft office. The first frustration was not so much with the program but rather with the lack of hardware standards. The headset microphone which I used with my I'm back iMac computer would not plug in to my two she bought to shave up Touche in the Toshiba laptop.
