Acoustic-labial Speaker Verification

This paper describes a multimodal approach for speaker ver-iication. The system consists of two classiers, one using visual features and the other using acoustic features. A lip tracker is used to extract visual information from the speaking face which provides shape and intensity features. We describe an approach for normalizing and mapping dierent modalities onto a common conndence interval. ...

Experimental Verification of Acoustic Saturation

The maximum value of acoustic pressure within an ultrasonic beam is limited by acoustic saturation. The t oretical basis for acoustic saturation has been analyzed previously. In this work, a high-power pulse source is used to drive acoustic pressure levels from an ultrasonic beam to saturation. An automatic procedure determines the field’s beam axis using a calibrated Marconi PVDF hydrophone. T...
