The Effects of User's Training on the Performance of an Automatic Speech Recognizer for a Self-Paced Task

Abstract

The results of a recent experiment concerning the effects of training on the performance of subjects using the automatic speech recognizer are reported. Over a 5-day period, 20 military enlisted grade male subjects were trained and tested in using a connected speech (speaker-dependent) machine automatic speech recognizer in a self-paced task controlling a generic tactical display by voice command. Experimental results show that a majority of the subjects had little difficulty with the automatic speech recognizer and that for these subjects training produced only a slight improvement in recognizer performance. These subjects performed at a high machine recognition rate. However, during the first session, a large minority (35%) of the subjects had difficulty training their speech to be machine recognizable. These subjects required at least two training sessions to perform the task at their best ability, and even after they were trained, their performance never reached the performance level of other subjects.
