A system and method in a radio telecommunications network for correlating speech quality over an air interface link with a plurality of radio quality parameters. The system includes a mobile switching center (MSC) (13) for recording uplink radio quality information from the air interface link, a mobile test tool (12) for recording downlink radio quality information from the air interface link, a parser (16) for parsing the radio quality information into the plurality of radio quality parameters, and a memory (17) for storin g the parsed radio quality information. A digital audio tape (DAT) recorder (19) or personal computer (PC) is electronically connected to a mobile station for recording a speech conversation from the air interface link simultaneously with the recording of the radio quality information. A DAT- link interface (21) is utilized to interface the DAT recorder with a playbac k unit(26)and with a synchronizer/controller (22) which synchronizes the stored radio quality information and the stored speech conversation. The radio quality parameters are presented t o the operator in graphical form on a visual display (51) while the speech conversation is simultaneously presented to the operator in audio form (25). The operator enters a subjecti ve evaluation of the speech quality of the speech conversation, and the evaluation is correlated with the radio quality parameters and displayed on the visual display.
