Speech production maps onto a three-stage cascaded electrical circuit analogy

Evidence

The acoustically abstracted presentation in Figure 5.9 can be reduced further into the circuit analogy of Figure 5.10 that consists of three cascaded (= coupled in series) subsystems: the excitation (generator), a transmission line (a two-port), and a radiation impedance (acoustic radiation load). — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 599
