The vocal tract can be simulated as a cascade of acoustic transmission line segments

Evidence

Since the vocal tract can be considered an acoustic transmission line, it can be simulated computationally based on the idea of Figure 5.11 and acoustically on that of Figure 5.9. The vocal tract (and the nasal tract for nasalized sounds) can be approximated by a cascade of transmission line segments, as shown in Figure 5.13. This is called the Kelly-Lochbaum model (KL-model) (Kelly and Lochbaum, 1962), where the vocal tract cross-sectional profile A(n) is mapped onto reflection coefficients k(n): The principal advantage of articulatory synthesis is that the dynamics of the speech production systems are included in a natural way. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 622
