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?
