Communication in the maritime environment is important for safety but does not always run smoothly. This can have catastrophic consequences. After all, 90% of all accidents at sea are caused by human error, and half of these by problems with communication. In collaboration with Jade University of Applied Sciences (Elsfleth Campus) and partners from industry, Fraunhofer IDMT in Oldenburg, Germany, has been working for some time on improving safety-relevant voice communication, particularly at sea.
