What is TD Snap Core First? 

TD Snap Core First offers a simple yet robust way for people who can’t speak to combine words and symbols for effective communication. It is based on core words, a small set of flexible words that make up roughly 80% of what we all use in many daily situations, carefully placed and ordered for easier recall.
