Narrative:

Aircraft X departed chs northwest to cae during very busy traffic. Climbed to 6000 ft, aircraft Y 6000 ft overflt southwest towards sav. I got extremely busy and did not see conflict until conflict alert activated. Called traffic at 3 mi and turned aircraft Y south. Aircraft Y reported traffic in sight. I was working approximately 15 aircraft at this time, one of which spoke broken english and was not responding to my calls. I diverted my attention to concentrating on getting an acknowledgement from foreign pilot when incidents occurred.
