Human Factors; Procedure
Initial filed clearance was modified from LIH-V15-HNL-EBBER to LIH-V15-MKK-EBBER taking us more south. Oceanic Track was the Echo Track. When given the takeoff clearance we were assigned an initial heading of 080. After departure and checking in with Honolulu Control Facility (HCF); we were given the clearance to proceed direct to ELOYE. With the noise in the flightdeck we thought it was OLOYE which was the next waypoint ahead of us on V15 (our clearance route). HCF noticed our turn and asked us to verify we were going to ELOYE; not OLOYE. We saw the error; told HCF that yes we were going to OLOYE and were correcting. HCF said that 'a number of you guys have been doing that lately.' We told him it was an easy mistake to make if you were given the Echo Track and that we would pass on the information about the possible confusion.[Review of the reported fix names revealed the reporter may have miss-spelled them; it is highly likely the actual fixes confused were ELOYI and OLOYI.]
Air carrier First Officer reported incurring a track heading deviation after confusing similar sounding fixes ELOYE and OLOYE. [Review of the reported fix names revealed the reporter may have miss-spelled them; it is highly likely the actual fixes confused were ELOYI and OLOYI.]
