Resonant frequencies and the vocal tract length

This post is about resonant frequencies of a tube, in the context of speech and the neutral vocal configuration. Two formulas are given: the first to calculate the resonant frequencies when the length is known, and second, to calculate the length when the frequency of a formant is known. Finally, there is a real-life example: […]

Physics of Speech

Once set in a vibratory motion, the vocal folds create a series of movement within the vocal tract above the larynx (the rate at which vocal folds vibrate is recognized as the fundamental frequency of sound). An object will increase the vibrations [2] that are close to its own natural frequencies.  In speech, some frequencies are dampened, […]

Sound (Related to Speech)

Sound is a form of energy (Crystal 32). It is a series of pressure fluctuations in a medium (Johnson 4). In speech the medium is usually air, although sound can propagate through solid objects and water, for example. Once the air particles become energised by the vocal folds vibration, a series of rarefaction and compression […]
