Good day, my task is to do word identification. I have used the pspectrum spectrogram function in order to aquire the power, time and frequency of a word. I was told to use the time-frfequency characteristics obtained and compare it to the time frequency characteristics of other words. This however, does not work for me as I constantly obtain incorrect results. The time frequency graph I obtain is often a linear graphs with gradients varieng by so little for every word. Example:
Does anyone know what characteristics of a sound wave can be used to compare to others' and to find out which word is the most similar/the correct word? I've tried so many things resulting in failure. Thanks!
