EVALUATION OF VOICETYPE DICTATION FOR WINDOWS FOR THE RADIOLOGIST

The accuracy of the radiology vocabulary domain of the IBM VoiceType D ictation for Windows speech recognition system for use in a clinical s etting was evaluated. Six men and one woman dictated a case report und er several conditions. The impact of vocabulary domain, microphone pos ition, personal enrollment, and background noise were assessed. The di ctations were exported to Microsoft Word 6.0, printed, and graded for accuracy. The data were expressed as a percentage correct. The enrollm ent and training processes took an average of 5 hours to complete. The accuracy of VoiceType Dictation was significantly reduced by speech v olume and background noise level so that it could not be used to dicta te clinical information accurately in a hospital setting. Although IBM 's VoiceType Dictation with the radiology vocabulary domain has improv ed speech recognition, it is not a reliable dictation system for accur ate and efficient clinical dictation in a hospital setting.
