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.

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.

Audiometer

Last Wednesday (17.10.2018) we obtained our first audiometer. With this audiometer we are able to conduct both pure-tone audiometry up to 12.5 kHz and basic speech intelligibility tests. The tests may be perfomed for either air/bone conduction or in the free field. Now we can analyze the hearing capabilities of our test subjects, which will help us when performing subjective tests. Special ...
