Patent Abstract: Methods of using individually distinctive patterns of voice characteristics to identify a speaker include computing the reassigned spectrogram of each of at least two voice samples, pruning each reassigned spectrogram to remove noise and other computational artifacts, and comparing (either visually or with aid of a processor) the strongest points to determine whether the voice samples belong to the same speaker.
