VOCAL-ONE provides an audio announcement of alert messages from FEMA’s IPAWS system. The device uses text-to-speech technology to convert text messages to audio which is spoken using its built-in speaker. It speaks the broadcasted messages to devices within a specific geographic area of concern (multiple languages are supported). The message can be directed to tens, hundreds, thousands, or even millions of devices simultaneously. Controls allow for the repeat of messages automatically or on demand. An external amplified speaker for large public spaces can be integrated.
