Summary:A number-of-recognition candidates determining system in a speech recognition device, for calculating the similarity between a plurality of preliminarily registered speeches and an inputted speech and outputting as recognition candidates a predetermined number of said registered speeches at higher order in similarity, comprises an SN ratio calculator (15) for calculating an SN ratio of an inputted speech to the environmental noise, and a number-of-recognition candidates controller (16) for controlling the number of the recognition candidates according to the value of the SN ratio calculated by the SN ratio calculator. The number of recognition candidates is varied according to the value of the SN ratio.
