Abstract: Techniques for voice announcements over communications paths in siren systems are provided. In one aspect, a siren activation sequence including an audio identification sequence may be received at a siren alert site controller over a data communications channel of a first communications path. The audio identification sequence may be extracted from the siren activation sequence. A first combined audio signal may be received at the siren alert site controller over a voice communications channel of the first communication path. It may be determined that the first combined audio signal includes the audio identification sequence. The audio identification sequence may be extracted from the first combined audio signal to create a first audio signal. The first audio signal may be played over a siren controlled by the siren alert site controller.
