Abstract: Described are methods and devices for receiving a missed message signal, detecting an ambient noise level, determining whether the ambient noise level is at least at a predetermined ambient noise threshold value based on the detected ambient noise level. When the ambient noise level is determined to be at least at a predetermined ambient noise threshold value the methods and devices include processing missed message alert data of the missed message signal for annunciation of missed message alert data. Processing can include storing the missed message alert data to wait for the ambient noise level to be low enough so that an annunciation of the missed message is audible over the ambient noise. Annunciation of a message alert can be, for example, by audio signal output when the ambient noise is low enough that the alert may be heard by the user.
