Speaker Identification using Spectrograms of Varying Frame Sizes

Abstract

A spectrogram describes how the spectral density of a signal varies with time. The most commonly used form of a speech spectrogram is the frequency versus time plot with a third dimension indicating the amplitude of a particular frequency at a particular time represented by the intensity or color of each point in the image.
