Advances in speech recognition over the last 20 years have been heavily driven by three factors: more data, more computation, and lots of competition. This talk will describe how these factors have driven the error rate on large vocabulary continuous speech down by more than a factor of four over the last several years, using various examples from signal processing, acoustic modelling, and language modelling. The talk will conclude with a demonstration of some technologies that have resulted from this progress, including IBM's latest speech dictation product, ViaVoice 98.
