Piglet grunts were recorded in 2014 and 2015 at the research farm of
Institute of Animal Science in Prague. To elicit the calls piglets were
separated from the litter and sow and were recorded in social isolation in
age of 25-30 days after birth from the distance of 1m. Piglets were recorded
opportunistically during the day. The original dataset comprised 97 piglets
coming from 13 different litters and 10 calls per individual piglet.
Variables were selected to be the most informative regarding the individual
identity by the reference study. Variables were extracted using the LMA 2008
software for analysis of animal sounds by Kurt Hammerschmidt.
