Implementation and Evaluation of Commercial Off-The-Shelf (COTS) VoiceRecognition Software as an Input Device in a Windows-Type Environment

摘要

This thesis investigates the implementation and evaluation of commercial off-the-shelf (COTS) voice recognition as an input interface within a windows-type environment. The three software packages implemented and evaluated are DragonDictate For Windows version 1.3, VoicePilot 2.0 (both manufactured by Dragon Systems, Inc.), and IN3 Voice Command for SPARCstation version 2.2.2 by Command Corp. VoicePilot and DragonDictate are both installed on PCs running MS Windows 3.1, and IN is installed on a SPARCstation running OpenWindows 3 and SunOS 4.1.3. Several applications are manipulated using voice recognition with these three software packages. The results of this study show that DragonDictate has the most flexibility and ease of use as an input device for a windows-type environment. It is also shown that as usage increases, DragonDictates recognition accuracy is able to be improved to above 98%. Other areas of future research are also suggested.
