Analysis of short duration speech using time-frequency methods

Abstract:

Spectrograms come in two flavours - wideband and narrowband. Your choice of flavour will be determined by whether you wish to examine either short duration events speech events or measure fine frequency resolution. But can you have both?

Using a technique known as the minimum cross entropy time frequency distribution (MCE-TFD) technique, improved time and frequency resolution can be achieved, providing more detailed information about the speech signal. To illustrate this point, spectrograms and MCE-TFDs will be compared showing difference for both deterministic signals and speech signals.
