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.

TensorFlow and Escape Rooms

The last two days (Monday and Tuesday, September 16 and 17, 2019), the whole DSS team did a course on TensorFlow and Keras. Since we already have interfaces of TensorFlow to our real-time tool KiRAT, it was time now to extend our knowledge on graphs and the corresponding training of weights, biases, etc. After two days of hard work we booked two escape rooms and solved the "secrets" hidden in ...
