Abstract: A system that incorporates the subject disclosure may include, for example, receiving first and second audio input signals from first and second communication sources. First and second emergency alert system messages are respectively identified from each of the first and second audio input signals. A temporal overlap is detected between a portion of the first emergency alert system message and the second emergency alert system message. In response to detection of the temporal overlap, a relative delay is applied between the first and second audio output signals. First and second audio output signals are generated including the first and second messages adjusted by the relative delay, such that the first and second emergency alert system messages in the first and second audio output signals are non-overlapping. Other embodiments are disclosed.
