Shadowing in any language

How many words Sada recognised, by language

Test run on 2026-09-25: sentences spoken by clear synthetic voices and heard by Sada’s own speech model (the larger one on computers, the smaller one on phones). A learner’s voice is harder, so the numbers compare languages. Japanese is weak on phones for now; practise it on a computer.

Any other language

The table lists the languages we tested, but Sada takes any video with captions. Try yours: if most of your words turn green on a clear line, it hears that language well.

What is shadowing?

Practise one line, step by step

1. Try an English example, or add a video in your language with captions and choose a line you understand.
2. Listen and read the caption, then say the line after the speaker in Repeat mode.
3. Try saying the line with the speaker in Shadow mode, following the rhythm and pauses.
4. Record a take, then open Compare and play your recording and the original. Review words and timing; Sada does not grade individual sounds.
5. Repeat the line while focusing on one difference you heard, then move to another line.
