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.

Example for free speech

Free speech   Male   Video example (audio is switched off by default, if you want to hear it, please active the audio part in the lower part of the video)
         
Test sentence:    
    Jawohl hören sie, hier spricht Rudolf Ranick hier vom FTZ. Prüfen Sie bei Kurt Meyer in der Burgstraße den Leitungsanschluss und auch das Geräusch aus den Kapseln.   
        Ich bin heute hier und teste unsere neue Schwimmbrille.

MIMO SONAR System

Recently, we get the new projector front-ends from Atlas Elektronik for our MIMO SONAR system. This was part of the "Großgerät" which was obtained with the help of the German research foundation (DFG). Now we are able to perform underwater experiments that will show if our ideas and corresponding realt-time algorithms also works in real environments.

We would like to thank all of our ...
