The Effects of Certain Background Noises on the Performance of a Voice Recognition System.
Richard S. Elster · Defense Technical Information Center (DTIC) · 1980
This report describes an experiment concerning the influence of different levels of background noise on the performance of a voice recognition system. Three levels of noise were used: 38, 65 and 75dBA. The results suggest that if the device is trained at 38, 65, or 75dBA, performance will be satisfactory in 38 or 65dBA environments, while to be used in a 75dBA environment, the device should be trained in a 65 or 75dBA environment.
