An Augmentative and Alternative Communication (AAC) Aid that I wrote for my son Ben, which is hopefully useful for others too. It's written in Rust for reliability and speed and uses iced underneath. Ben DOES NOT tolerate slow things, and this absolutely MUST NOT crash either! His current AAC apps are slow, so he doesn't like using them. I hope he likes OneTalker better.

Using the feature list from OpenAAC as a guide, OneTalker aims to provide a simple, easy to use, and highly customisable AAC application that can be used on a variety of platforms including Windows, macOS, Linux, and potentially others in the future.

I personally like this:

From the AAC Institute Mission Statement:

The two most important values expressed by people who rely on AAC are:

1. saying exactly what they want to say
2. saying it as fast as they can

Progress To Date
