Interactive speech recognition system

摘要

The invention relates to an interactive speech recognition method for recognizing an input spoken phrase, an interactive speech recognition system and a computer-readable medium. To improve the memory management of the system and to enhance the safety in, for instance, the road traffic, and to reduce user interaction to a minimum level, the invention suggests to iteratively analyse an input spoken phrase on per category basis taking into account the available memory for loading lists of reference terms in each iteration. More specifically, reference terms of a particular category are iteratively matched to terms of the spoken phrase and if one or more matching term is found the system determines whether the memory for loading a list of reference terms for the next iteration for each matched reference term would be sufficient. If not, supplementary input from the user is requested.
