An improved speech recognition system with at least two speech recognition engines which may or may not be identical. Each of the speech recognition engines supply a recognized-text output signal each of which are provided to a text comparator. The comparator compares the recognized-text output signals and accepts or rejects the text based on the degree of agreement between the output signals from each of the engines. Completely different types of speech recognition engines can be employed. Alternatively, identical speech recognition engines could be employed with a slight perturbation added to one of the engines or the input signal of one of the engines. Alternatively, the very same speech recognition engine could be used at two different points in time, with one receiving some type of perturbation.
