Puff of air (aspiration)
The sounds 'p', *t' and 'k' (unvoiced stops) have an extra signal to distinguish them clearly from 'b\'d* and 'g' (voiced stops). This signal is an extra puff of air.
If you hold a piece of paper in front of your mouth you can test yourself. The paper should move when you say a voiceless stop with a puff of air. The paper will not move without die puff of air. You can also test yourself by holding your hand in front of your mouth. You should feel the difference between the presence and absence of the puff of air.
