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 […]

The Speech Organs and Airstream

Speech is produced by the speech organs, where airstream  causes the vocal folds to vibrate (this applies to the egressive airstream mechanism). The created sound then moves through the articulatory system, attaining its final form – one of the sounds used in the language of the speaker.  This text is an overview of what happens […]
