About Sandi

Speak & Improve is a research project from the University of Cambridge. By using it you are helping us improve technology that will help English learners around the world.

  1. Talk to our speech robot, Sandi, who will ask you some questions.
  2. Afterwards, Sandi will give you a grade for your speaking.
  3. Were some questions difficult for you? Try them again to improve your score.

Sandi, our speech robot, uses new technology developed at the University of Cambridge.

It can tell how well you speak English just by listening to you. Sandi gives your Speaking an accurate grade on the internationally-recognised CEFR scale.

This can help you understand your speaking ability for work, study, exams (including Cambridge exams), or just for fun.

Complementarily, there is also an English writing level tool developed by the University of Cambridge, available without registration. ( )

It provides English learners a platform to practice their written English, and upon submitting their writing results, they will receive feedback associated with the international standard CEFR within a few seconds. The automatic evaluation highlights areas where your writing may need improvement and supports users of various English writing levels, such as beginners, intermediate, and advanced.
