RescueVoice is a purpose-built speech-generating app engineered specifically for first responders and medical personnel to use with individuals who have limited speech or who are unable to speak because of a medical event.

The application contains both tap-to-talk icons and text-to-speech capabilities. Pre-stored vocabulary related to symptoms, pain, body parts, allergies, medications, people, time, and places is included based on feedback from first responders and individuals who use augmentative and alternative communication (AAC).
