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.

Since early summer, Julius Braun-Dullaeus, David Thesing and Martin Semmelrodt have joined the DSS team, bringing expertise in embedded systems, sensor hardware and physics. Julius has been connected to DSS throughout his studies, working on stochastic modeling and underwater signal processing. His current work focuses on a drone-based system for localizing and classifying magnetic objects. David continues his master’s research at DSS, combining thin-film sensor development with real-time signal processing for 3D SONAR beamforming. Martin joined in August after completing his master’s degree in theoretical physics. Having first encountered DSS through a collaboration at Müller-BBM, he now works on drone-based magnetic detection of underwater objects and will take over the project from Julius in January.
