Welcome to the English sound by sound practice app. This is the accompanying app for the full online “English sound by sound” course. We designed this app to help you master your english sounds and give you something you could use on the go. Anytime you have doubt about a sound, or how to say something, simply go to that sound, listen and then practice. It’s that simple.
支援平台：iPhone, iPad
