WebOct 12, 2024 · spectrogram: [noun] a photograph, image, or diagram of a spectrum. WebRegions of frequency space where speech sounds carry a lot of energy are known as " formants ", and these formants arise from resonances in the vocal tract. Speakers change the resonance frequencies by moving their "articulators" (lips, jaws, tongue, soft palate), and thereby changing the dimensions of the resonance cavities in the vocal tract.
