Abstract:
A reference archive has been constructed to facilitate research on automatic
recognition of marine mammal sounds. The archive enables researchers to have
access to recorded sounds from a variety of marine species, sounds that can be
very difficult to obtain in the field. The archive also lets researchers use
different sound-recognition methods on a common set of sounds, making it
possible to compare directly the effectiveness of the different methods. In
recognizing sounds in a given recording, the type and frequency of noise
present has a strong effect on the difficulty of the recognition problem; a
measure of the amount of interference was devised, the "time-local, in-band,
signal-to-noise ratio", and was applied to each sound in the archive. Current
entries in the archive comprise low frequency sounds of large whales, and have
about 14,000 vocalizations from eight species of baleen whales. MobySound may
be accessed at http://hmsc.oregonstate.edu/projects/MobySound/. Contr
ibutions to the archive are welcomed.
