Easy Speak AI
Practice English with an AI conversation partner. Get instant feedback on pronunciation, grammar, fluency, and vocabulary.
Independent App Developer
I design and ship simple, focused apps for iPhone and Android — relaxing puzzle games you can pick up in a spare moment, and one AI companion for people who want to speak English with more confidence.
The puzzle titles share the same idea: clear rules, short sessions, and a little more challenge the longer you play. Easy Speak AI takes a different path. Instead of memorizing word lists, it invites you into a real conversation and gives instant feedback on pronunciation, grammar, vocabulary, and fluency.
All of these apps are published under HANG KIM DUYEN. If you play one of the games or practice with Easy Speak AI, thank you — that is the whole point of the work.
Available on the App Store and Google Play.
