Glosso: English Pronunciation

Learn English by speaking it, and know exactly how you sound. Glosso is an English course built around your own voice: in every lesson you read, listen, answer and speak, and your pronunciation is measured sound by sound. No ads. No account required.

* LESSONS THAT MAKE YOU SPEAK
Each lesson starts with a dialogue, a story or an article you can read and hear line by line. Then come exercises, a step where you answer from memory, and pronunciation drills on the sounds of that lesson.

* AMERICAN OR BRITISH ENGLISH
Choose the accent you want to learn. The texts, the spelling, the phonetic transcription and the reference voices switch together: "Mom" and "favorite" in American English, "Mum" and "favourite" in British English.

* YOUR TURN
You hear the other person's line and say yours without reading it. The sentence appears once you have said it. It is the closest thing to a real conversation you can practice on your own.

* DRILLS FOR EVERY SOUND
Each drill pairs the sound with the one it gets confused with ("think" and "sink"). Hear the reference at normal or slow speed, say the sentence and listen to your own take.

* MEASURED PRONUNCIATION
Speak and get a score for every word and every sound. See exactly which sound slipped, hear the reference again and try once more. When a recording cannot be judged, the app says so instead of giving you a low score.

* PRIVATE AND OFFLINE
Glosso can score your voice on your device. Download the model once and practice without a connection: on a plane, on the subway, at home. In the current beta, scoring may use our server instead, and the app tells you when. Your audio is used only to score your attempt: never sold, never used for ads.

* YOUR PROGRESS
See which sounds you have mastered and which need work, with your own trend over time, daily streaks and achievements.

* LANGUAGES
The English course (American and British, levels A1 to B2) is available today, and a Russian course is new at level A1, written from Russian culture, with A2 to B2 coming later; scoring Russian needs a connection. The app interface is translated into English, Spanish, French and German. More courses are planned; French, German and Spanish come next.

PERFECT FOR
- Learners who want their spoken English to be understood
- People preparing the speaking part of an exam (IELTS, TOEFL, PTE and others)
- Business professionals and public speakers
- Immigrants and expats adapting to a new country
- Teachers and tutors of pronunciation or accent training

Glosso is in open beta and free while it grows. Download it and start speaking with more confidence: honest, private feedback, on your phone.

Recent changes:
Glosso 2.5.4. To improve the course during the beta, usage statistics are more complete: which screens and audio get used, how review goes and where things fail, linked to a random installation id. The app also sends crash reports so problems get fixed faster. No audio, no ads, no third parties. You can still turn it off in Settings > Usage statistics. Still free during the beta.
