This chapter is intended to give the reader information on how to measure the performance of an automatic speech recognition system. In order to do so, the range of types of recognition systems and the applications for the system must first be specified, as this is important for the assessment method.
Much effort in defining standards for assessment of automatic speech recognition (ASR) systemsautomatic speech recognition system has been invested by the ESPRIT SAM consortium. The reader is therefore referred to the final reports of SAM [SAM (1992)].
