Discussions between the on-field and television umpires will be aired during Australia's upcoming one-day series against South Africa.
The International Cricket Council (ICC) is conducting the trial during the five-match series, with a view to using it at select matches in the World Cup.
The first match is at Perth on Friday.
"This initiative is part of ICC's efforts to make umpiring more understandable to viewers and spectators," said the governing body.
"The umpire communications can be aired during umpire referrals, consultations and DRS (Decision Review System) player reviews."
England's Nigel Llong and New Zealand's Billy Bowden will be the two on-field umpires throughout the one-day international series, with Australian umpires taking turns in the third umpire's chair to oversee TV replays.
South Africa and Australia, who are ranked second and third respectively in the 50-over world rankings, can both replace India at the summit depending on the series result.
The 2015 World Cup is being held in Australia and New Zealand between 14 February and 29 March.
