Measuring vocal-tract impedance at the lips: model, hypotheses and limits

Abstract : Non-invasive techniques (such as the so-called RAVE) were developed to characterize vocal-tract acoustics using a broadband excitation and a microphone positioned closed to the lips. The measured pressure for an open-mouth condition, calibrated by a mouth-closed reference condition, provides estimates of the radiating vocal-tract resonance frequencies. Recently, exponential-sweep-based methods were reported to measure vocal-tract impedance. We propose to explicit the underlying hypotheses of such approaches, and to test their validity domain.
