IELTS-style speaking practice

Push to talk with an AI examiner through the full IELTS-style speaking test, then get a band from 1 to 9 for fluency, vocabulary, grammar and pronunciation, an overall band and Tera's feedback.

1. Part 1Questions about you, about 5 minutes
2. Part 2A cue card, with one minute to prepare, a 1 to 2 minute talk
3. Part 3A wider discussion, about 5 minutes

Five free sessions a day, no account needed. The bands are practice estimates from a transcript of what you said, so the pronunciation band is the roughest, and they are not an exam result.
