## What is Echo?

Echo is an AAC app designed for those with a visual difficulty and physical difficulty to access communication.

Echo is based around the concept of auditory scanning. Auditory scanning is a communication method using sound cues or auditory feedback rather than visual cues. This method is especially valuable for those with a visual impairment who cant access visual based AAC.

Echo provides you with two different voices, one for your auditory cues and the another to represent your voice.

You can access Echo using the following methods. 
- Any external switch (or combination of switches)
- Swipe Gestures
- Arrow Keys

We have plans to extend this in the future to allow for more access methods.

## Key features

- Auditory scanning communication method
