This app is for anyone that needs it, and we're happy to make changes to it so that more people can use it. We've been told that a way to add pictures would be nice, and we'd love to add that feature in. We're focusing on words and sentences right now just because it's something that isn't widely available.
This is an open source application that helps people who can't speak communicate with others. I posted the Android github, but it's also an iOS project. Along with development help, we also need help translating this app.
This looks incredible! I come across people who are trying to use our service (speech synthesis) and are looking for a complementary services like this all the time. The closest thing I've come to recommend is https://talktablet.com/.
Cool to see AAC trending on hacker news! My wife is an SLP so the speech language/tech intersection is a point of interest for us. If I may ask: how did you source contributions from SLPs?
