Yes. Alternate formats can be issued, but not every alerting authority or every device will have the capacity to produce alternate formats. For example, emergency alerts distributed via radio and television broadcast can include an audio file version of the text portion of the emergency alert message, if one is provided by alerting authorities. If audio files are not provided, broadcasters may use text-to-speech software to create an audio version of the message. For emergency alerts distributed via compatible wireless devices, emergency alerts may be read to the recipient if their device supports this accessibility feature. The vibration feature that accompanies emergency alerts sent to compatible wireless devices will help to make hearing impaired people aware of the alerts.
