Introduction, its fundamental frequency, which is heard as a pitched tone (melody). Moreover, the complicated mechanical nature of the vocal cord vibration gives rise to a series of harmonic frequencies in the sound, which are integer multiples of the lowest frequency.

History of Speech Spectrum Analysis,re still widely known and cited, while others’ contributions have been unjustly forgotten. With this chapter, I also hope to straighten out the historical record in this respect, giving all due credit to those pioneers who uncovered many facts about speech spectra that are now taken for granted.

The Reassigned Spectrogram, points around tighter lines in both the frequency and time dimensions. This approach relies on the understanding of the spectrogram as showing instantaneous frequencies of line components, and sharpens that view of things while doing away with the idea of showing how energy is distributed in the time–frequency plane.
