Speak English in 30+ real-world scenes with an AI partner that listens, responds, and gives you real-time feedback — one conversation at a time.
Start Practicing用 "while" 构建对比，比 "and...because" 更清晰有力
You can ace the written exam, but freeze up in the speaking section.
You understood the whole lecture, but stayed silent during discussion.
You know what to say, but the words just won't come out.
EchO is built for this exact gap —
between knowing English and speaking it.
EchO is a product that helps you practice speaking English through voice-based conversations. Pick a scene, talk to your AI partner, and get a detailed report scoring naturalness, coherence, appropriateness, sentence variety, and grammar after each practice. Save useful expressions to your personal notes and review them with spaced repetition — so you actually remember what you learn.
Choose from 30+ real-world scenes — office hours, job interviews, team standups, and more. Or import your own materials to create a custom scene.

After each practice, see exactly what to improve: grammar fixes, better phrasing, scores across five dimensions, and expressions worth keeping.
Top Issue
give people a comfortable feeling “feel intuitive”
Practice the conversations you'll actually have — pitching to a client, joining a team meeting, chatting over coffee, or presenting your research.
Speak naturally and hear your AI partner respond in real time. No scripted dialogues. No fill-in-the-blanks. Just real practice for real situations.
Each time you speak, EchO analyzes your sentence and shows you a better version — where you used awkward phrasing, missed a collocation, or could sound more natural.
After each practice, get a scorecard: naturalness, coherence, grammar accuracy, and more. See your top issues and recommended expressions.
Every correction and useful expression is automatically saved. Organize them into collections and watch your phrasebook grow from conversations.
Saved expressions become flashcards. Review a few each day and turn short-term corrections into long-term habits.
Whether you're acing an interview, joining a meeting, or making small talk — there's a scene for you.
