Everything you need to study
Four tools that work together, sharing one picture of what you already know.
Vocabulary lists
Build clean word lists with pronunciation, meanings, and example sentences. Star the ones worth coming back to.
Dictation
Hear a word, type what you heard. Quiet, focused feedback that keeps you in the flow instead of grading you.
Flashcards
Flip through words and sentences at your own pace, filtered to exactly what you want to review.
Review what matters
Every tool shares one sense of what you know. Mark a word Got it once and it follows you everywhere.
Built-in audio
And every word reads aloud.
Audio isn’t a separate step — it’s part of every list, card, and quiz. If you can read it, you can hear it.
Tap any word
Headwords, meanings, example sentences — touch the text and it speaks. No buttons to hunt for.
Native voices
Real, natural pronunciation in Chinese, Japanese, Korean, and English — built in, nothing to install.
Read along, out loud
Hear a sentence, then say it back. Listening and speaking, woven into every list you study.
For teachers

Soundu isn’t just for studying on your own — it’s where you build, assign, and track vocabulary for a whole class. Teaching tools appear automatically once you create your first course.
AI-built word lists
Type the words — AI fills in pronunciation, meanings, example sentences, and mnemonics in any of the four languages.
