Human Factors and Behavioral Science: Toward Bell System Applications of Automatic Speech Recognition

The potential of Automatic Speech Recognition (ASR) in telecommunication applications has long been recognized, 1 but until recently the state of ASR technology did not warrant effort beyond the existing laboratory activity. In the past few years, ASR has emerged from the laboratory into commercial use. Several systems are now available providing speaker-dependent word recognition. 2 Such a system must be trained by each user before it can recognize that user's speech. * American Bell. ®Copyright 1983, American Telephone & Telegraph Company.
