A visual presentation of a simulated communication unit moving through a wireless communication system is combined with an audio presentation of speech that a user would hear if the users were placed in the same radio environment. In addition, both audible and visual indicia of RF interference may also be provided (107, 109), with or without audio playback, to aid in designing around interference sources and their intensities. A set of error masks and corresponding audio files are created, wherein each file contains the same audio track, but based on speech error masks created at different vehicle speeds and signal to noise ranges. Real-time playback of the audible signal with noise is useful in planning for particular needs of a wireless communication system planner.
