Abstract
Communication for processing relevant information plays a paramount role in developing a comprehensive understanding of Search and Rescue (SAR) situations and conducting operations in a successful and reliable manner. Nevertheless, communication systems have not changed considerably in the context of simplifying very high frequency (VHF) maritime communication and enhancing the value of SAR practices. The Automated Transcription of Maritime VHF Radio Communication for SAR Mission Coordination (ARTUS) project approaches this problem with the development of an assistance system which employs AI-based speech recognition and smart direction finding. First, ideas and specified needs of end users for designing the user interface are presented in this paper. Further, preliminary accomplishments of domain specific language training for maritime speech recognition, and the direction-finding algorithms for localizing senders are sketched out. While the preliminary results build a solid ground, additional field experiments will be conducted in order to enhance the accuracy and reliability of speech recognition and direction finding. The identified end user requirements across different personnel groups show commonalities, but call for a differentiated approach in order to meet the challenges and peculiar needs of the various working contexts.
Highlights
Maritime very high frequency (VHF) radio is a robust and reliable communication system that has been established in international shipping for decades and is mandatory on board Safety of Life at Sea (SOLAS) ships in all sea areas [1,2]
The limitations of VHF radio are sometimes visible in certain working areas and situations, including in coastal radio stations where human radio operators are listening on several relays simultaneously and/or in maritime search and rescue (SAR) operations which are characterized by a considerable communicative workload
Supporting the work of SAR personnel with an adequate assistance system was the motivation for the ongoing research projectARTUS, whose system approach and preliminary results are described in this paper
Summary
Maritime very high frequency (VHF) radio is a robust and reliable communication system that has been established in international shipping for decades and is mandatory on board Safety of Life at Sea (SOLAS) ships in all sea areas [1,2]. The limitations of VHF radio are sometimes visible in certain working areas and situations, including in coastal radio stations where human radio operators are listening on several relays simultaneously and/or in maritime search and rescue (SAR) operations which are characterized by a considerable communicative workload. In these settings, maintaining an overview, selecting, and documenting all essential information is a challenge that is currently technically unsolved [4]. Supporting the work of SAR personnel with an adequate assistance system was the motivation for the ongoing research projectARTUS, whose system approach and preliminary results are described in this paper
