The speech tract is modeled as a transmission line with pressure and volume-velocity variables
Evidence
In Figure 5.10, the variables are ps (pressure from the lungs), ug (volume velocity at the glottis), as well as um and un (volume velocities at the lips and the nostrils, respectively). If the behaviour within the vocal or nasal tract is of interest, these blocks must be described as distributed wave propagation subsystems. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 599
