16. The system of claim 11 , wherein the one or more campaign configuration parameters comprises a calibration parameter that indicates that a calibration test should be performed, and wherein the end user device is further programmed to: configure the computer program instructions to perform a calibration test prior to generating the audio recording, wherein to perform the calibration test, the end user device is further programmed to: determine a level of ambient noise; determine whether the level of ambient noise satisfies the calibration test, wherein the one or more utterances to be uttered are displayed responsive to a determination that the ambient level of audio satisfies the calibration test.
