Abstract
A method for predicting a misrecognition in a speech recognition system, is based on; the insight that variations in a speech input signal are different depending on the origin of the signal being a speech or a non-speech event. The method comprises steps for receiving a speech input signal, extracting at least one signal variation feature of the speech input signal, and applying a signal variation meter to the speech input signal for deriving a signal variation measure.
