Abstract:

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.
