Voice Evacuation System

Voice evacuation is a method for emergency notification to alert people by human voice with generated tones and verbal instructions and initiate, proceed and/or announce a protocol. A voice evacuation system is a fire alarm system that features a mass notification system, an emergency warning and intercommunication system (EWIS), a tone generator amplifier, a PA system, or anything similar to that.

Tones and Voice Messages
The message "Evacuate the building using the nearest fire exit." is the most common voice message used typically for voice evacuation in Australia, and "Warning! The fire alarm has operated. Stand by for further instructions." as an alert message. The traditional Australian evacuation message, "Evacuate as directed." (sometimes preceded by "Emergency!", "Evacuate now." when urgent) was the first evacuation message used throughout the country of Australia and it is repeated twice "Evacuate as directed, evacuate as directed.". Although, there are other messages e.g "Fire! Evacuate now.", "Please evacuate the building immediately by the nearest fire exit." recorded by other Australian males. But there are messages used on North American fire alarm voice evacuation systems at a Queensland Woolworth's supermarket a Bargara, QLD. The messages were "Attention! Attention! A fire alarm has been activated in the building. Please wait for further instructions." followed by the command "Please evacuate." recorded by a US male for most Edwards EST systems used over in North America (the United Sates and Canada).

New Zealand
In New Zealand, its standard voice message for evacuation is "Evacuate the building using the nearest fire exit. Evacuate the building using the nearest fire exit." twice (2x), unlike the Australian version "Evacuate the building using the nearest fire exit." as it says only once (1x) after 16 seconds of the evacuation tone.

Examples
The standard tones and verbal (voice) messages are used to require the Australian standards to meet AS 2220, AS 1851, NZS 4512 etc. depending on the brand or make.

Here are the examples of tones and verbal messages. Note: The message "Evacuate the building using the nearest fire exit." different to the Australian and New Zealand. For the general standard version for New Zealand, the "Evacuate the building using the nearest fire exit" message is repeated twice (2x) per cycle, but the typical Australian version has a gap between the keywords "evacuate the building" and "using the nearest fire exit." and either of these versions have a different voice because of a brand of system.
