What is LingoChamp?

An English-learning app from LAIX (Liulishuo) built around a proprietary speech-recognition and pronunciation-scoring AI. It scores the English you speak at the phoneme level and evaluates and corrects pronunciation, vocabulary, grammar and fluency across multiple dimensions. Widely used in China as "Liulishuo," but LAIX was delisted and taken private in the US in 2022, and the international version has shrunk to mainly English (+ Spanish) with stalled updates (availability from Japan and a Japanese UI need to be confirmed).

About "LingoChamp"

What is LingoChamp

LingoChamp is an English-learning app built around a proprietary speech-recognition and pronunciation-scoring AI. It is provided by LAIX (Liulishuo). It scores the English you speak down to the phoneme (the smallest unit of pronunciation) and evaluates and corrects pronunciation, vocabulary, grammar, fluency and more in real time across multiple dimensions. In China it is widely used under the "Liulishuo" brand, with a reported 200 million-plus registered users.

Please note the current status. LAIX was once listed on the NYSE and expanded in multiple languages, but it was delisted and taken private in 2022 and has since refocused on a China-centered business. The international "LingoChamp" has narrowed to mainly English (+ Spanish), and its international app has not been updated since 2023. The previous claim of "6 languages supported" no longer matches reality. A Japanese UI and availability from Japan could not be confirmed (as of August 2026).

Scoring pronunciation at the "phoneme level"

At the heart of LingoChamp is having AI score the English you speak in detail and show what to fix and how. Rather than a simple pass/fail, it gives feedback via phoneme-level pronunciation reports and a multi-dimensional evaluation of vocabulary, grammar, fluency and pragmatics. It also offers conversation practice with "AI Mate," a GPT-based voice dialogue feature, and IELTS speaking prep (LingoIELTS).

Pricing

It is subscription-based, and the official site promotes things like a "3-day free trial," but specific amounts are not stated on the official site and vary by region. Please confirm the latest — including whether paid use from Japan is available — on the official site and app stores (as of August 2026).

How it differs from other English-learning AIs

LingoChamp is a pioneer of pronunciation-scoring AI, but as noted above its international expansion has shrunk and its international app has stopped receiving updates. If you want to use pronunciation/speaking learning in Japan right now, it is worth also considering services with more current support.

Aspect	LingoChamp	SpeakBuddy	Duolingo
Focus	Pronunciation scoring / speaking	AI English conversation (for Japan)	Comprehensive language learning
Status	China-centered; international version shrunk	Currently offered in Japan	Currently offered worldwide
Japanese support	Unclear	Yes	Yes

If a Japanese UI and support matter, consider SpeakBuddy; for gamified comprehensive learning, Duolingo; and to chat casually, Cotomo. We hope this page helps you understand LingoChamp as a pioneer of pronunciation-scoring AI, but please check its current availability before actual use.
