Criteria in the design of experiments for speech recognition performance assessment

L. O. Kingham

All manufacturers of speech recognition equipment claim near perfect recognition performance for their products, of 98% correct recognition or better. Few manufacturers put their performance rates into context, by describing the circumstances in which these measurements were made. In practise, performance rates in excess of 95% are achieved with very small vocabularies of dissimilar words, in ideal environments with consistent speakers.
