Portfolio Articulation

The third element of speech production is articulation. Articulation is the term used for all actions of the organs of the vocal tract that effect modifications of the signal generated by the voice source. This modification results in speech events which can be identified as vowels, consonants or other units of a language.

The passive place of articulation is the place on the more stationary part of the vocal tract where the articulation occurs. It can be anywhere from the lips, upper teeth, gums, or roof of the mouth to the back of the throat.

* The speech organs used to make the sounds are the tongue, lips and palate.

The human voice produces sounds in the following manner

1. Air pressure from the lungs creates a steady flow of air through the trachea (windpipe), larynx (voice box) and pharynx (back of the throat).
2. The vocal folds in the larynx vibrate, creating fluctuations in air pressure that are known as sound waves.
3. Resonances in the vocal tract modify these waves according to the position and shape of the lips, jaw, tongue, soft palate, and other speech organs, creating formant regions and thus different qualities of sonorant (voiced) sound
4. Mouth and nose openings radiate the sound waves into the environment.
