  • METHOD FOR DETERMINING WHETHER A MEASURED SIGNAL MATCHES A MODEL SIGNAL
    Publication number: 20150255058
    Abstract: There is provided a method for determining whether a measured signal matches a model signal, for example for use in speech or speaker recognition. The method comprises obtaining values of statistical features for the model signal; obtaining values of the statistical features for the measured signal; obtaining a signal to noise ratio of the measured signal; and comparing the values of the statistical features for the model signal to the values of the statistical features for the measured signal according to the signal to noise ratio of the measured signal, to determine whether the measured signal matches the model signal. There is further provided a signal processor configured to implement the method for determining whether a measured signal matches a model signal.
