Joint estimation of vocal tract and nasal tract area functions from speech waveforms via auto-regression moving-average modeling and a pole assignment method

Nasal resonance is utilized in certain languages to differentiate word meanings. The joint filtering effect by the vocal tract and the nasal tract can be modeled by the auto-regression moving-average (ARMA) approach. However, unlike all-pole (i.e., AR) modeling, it has been difficult to derive the e…
