In this paper an experimental setting is described which allows to separately record the speech signals emitted from the mouth and the nostrils. A series of transitions from an oral configuration to the nasopharyngeal configuration is then recorded with a speaker capable to control the movement of his velum while minimizing that of other articulators.

A beamforming method adapted to Stoneley-Scholte waves is presented, in the context of buried objects detection in the seabed. All the waves particularities are exploited in a wideband multicomponent array processing: velocity, dispersion and polarization. These propagation features must be estimated. The incident wave is used for this purpose. Then a(More)
A new system for buried object detection at the sea floor is presented. It is an alternative to SONAR systems using Stoneley-Scholte surface waves. The general processing method was presented in a previous publication. It is a multicomponent beamforming using an array of four component sensors set on the floor to detect echoes reflected by objects. In this(More)
