ASPIRATION

Closely related to the notion of voice onset time (VOT) is the notion of aspiration. The term aspiration means "pronunciation accompanied by breathing out." In the studies of voice onset time (VOT) in traditional phonetics, the focus of attention was on the sound or the airflow which filled the voice onset time (usually in the form of a puff of air). This quality was usually referred to as aspiration. When voiceless stop consonants take the word-initial position, they are often articulated with this added puff of air. Aspiration can be represented with the formal notations of systematic phonemics as the following phonological rule:

The symbol # marks word boundaries. If placed to the left (like in the above rule) it marks the initial position; when placed to the right, it marks the final position. As such, the above rule reads as: Voiceless stop consonants become aspirated in word-initial contexts. Compare the /p/ sound in words like pit and spit.
