Underwater Speech Examples

The following speech samples are recorded under water with microphones that were connected to swim googles. Here the idea was to used speech command such as "play", "stop", or "next/previos song" to control an MP3 player that is tipically weared on the backside of the head (kept to the head via the swim googles). The music signals are played either via waterproof headphones or bone-conduction loudspeakers (used in our case). Even a simple recognition scheme performed rather good for such "unusual" sounds.

Philipp is now "Doc Bulling"

On Monday, 10th of September 2018, Philipp Bulling sucessfully defended his dissertation on speech enhancement for in-car communication systems. His work focused mainly on the control of adaptive feedback cancellation filters (details can be found here). After an excellent talk Philipp gave very good answers to the questions of the committee and at around 11:30 h everythings war over and we ...
