A rule based system for speech verification is proposed as a feedback mechanism for speech recognition. The system provides an explicit way of selecting verification parameters depending on the item to be recognized and its context. An extended continuous logic is used to combine the evidence from different parameters and an automatic way to convert parameter values to logic evidence values is given. From the parameter evaluation and through the combination of logical values 9 an information weight is propagated to account for parameter extraction errors and poorly trained data.
