Summary: | In this paper, we report on communication experiments conducted in the summer
of 2022 during a deep dive to the wreck of the Titanic. Radio transmission is
not possible in deep sea water, and communication links rely on sonar signals.
Due to the low bandwidth of sonar signals and the need to communicate readable
data, text messaging is used in deep-sea missions. In this paper, we report
results and experiences from a messaging system that converts speech to text in
a submarine, sends text messages to the surface, and reconstructs those
messages as synthetic lip-synchronous videos of the speakers. The resulting
system was tested during an actual dive to Titanic in the summer of 2022. We
achieved an acceptable latency for a system of such complexity as well as good
quality. The system demonstration video can be found at the following link:
