Speech Recognition Technology Choices for the Warehouse

This White Paper reviews some of the basics of computer-based speech recognizers, including the challenges of maximizing performance. We then discuss technology choices in light of the needs of warehouse workers using speech recognizers, and calculate the cost of recognizer errors in the warehouse environment. For one of the major design decisions – whether to use a trained (“speaker-dependent”) or an untrained (“speakerindependent”) recognizer, we demonstrate that time spent in training the recognizer is
likely to be repaid in a few days by the benefit of improved performance.
