Communications are central to air traffic control and any potential intervention that might contribute to its increased efficacy is considered relevant. This paper explores two main characteristics associated with communications: aeronautical phraseology and intelligibility. Although phraseology may contribute to an increased precision of the message, several factors may hinder it through speech intelligibility. In this study, air traffic controllers were asked to reproduce several messages that vary in phraseology correctness and speech intelligibility. Results suggest that considerable attention should be given to factors affecting speech intelligibility as increased numbers of errors and omissions were reported in messages with this characteristic.
