This paper provides an overview of the Recogniser Sensitivity Analysis (RSA) methodology, under development by Logica within the UK Alvey Speech Technology Assessment (STA) project MMI/132, for assessing the performance of automatic speech recognition systems, both as products and as algorithms under development. The applicability of the method for predicting likely field performance in a particular application as well as its diagnostic capability will be discussed. Preliminary results indicate a very strong correlation between certain parameter values and recogniser performance as well as the potential for predicting field performance with limited data. The paper concludes with a discussion on future directions for extending RSA.
