TonePerfect for English
Free English accent test
How strong is your accent in English? Record five words and get a per-sound score in under a minute. The test is the same engine the app uses; it ranks your sounds against each other so you know what to fix first.
What an accent test measures
An accent is the sum of the sounds you substitute from your first language. The test listens to each sound in the five words, scores how close it is to a native model, and lists the ones that drift furthest. It is not a certificate and it does not grade grammar or vocabulary, only the sounds.
How it works
- 1
Record 5 words
Tap the microphone and read each word out loud. It takes about a minute, right in your browser.
- 2
AI checks every sound
Our speech engine listens to each sound inside each word — not just the word as a whole — and scores it.

See what to fix
You get a clear picture of which sounds are strong and which need work, with a tip for how to make each one. Then keep practicing in the app.
TonePerfect's English scoring runs on our own speech engine, and we validated it against human experts: a public research dataset of 2,500 recordings from 250 English learners, each rated by five human pronunciation raters. The engine's sound-by-sound judgments closely agree with those human ratings.
The sounds that decide your accent
The quiet 'th' (think)
The tongue tip touches the bottom edge of the top teeth and the air flows over it; no voice, and the tongue never taps.
The buzzing 'th' (this)
The same tongue-behind-the-teeth position as in 'think', with the voice buzzing through it.
The English 'r' (red)
The tongue curls back or bunches up in the middle of the mouth and touches nothing at all, while the lips round a little.
The 'l' sound (love)
The tongue tip touches the ridge behind the top teeth and the voice flows around the sides of the tongue.
The short vowel in 'sit'
Short and loose: the tongue sits a little lower than in 'see' and the whole mouth stays relaxed.
The long vowel in 'see'
Long and tight: the tongue is high and forward and the lips spread as if smiling.
Scores rank your own sounds against each other so you know what to drill first. They are not an accuracy certificate and not an exam grade.
Questions
How does the test work?+
You record 5 common English words, one at a time. Each word targets a sound that many learners find hard — th, r and l, the two 'i' vowels, v, and word endings. The AI scores every sound in every word.
What do the scores mean?+
Each sound gets its own score, so you can see exactly which sounds are already strong and which ones need work. A low score on one sound does not mean your English is bad — it shows you where practice will pay off fastest.
Do I need special equipment?+
No. Any phone or computer with a microphone works. Your browser will ask for permission to record. A quiet room helps the AI hear you clearly.
What happens after the test?+
You see your results right away, sound by sound. To improve the weak ones, continue in the TonePerfect app: it has a lesson and practice words for every English sound, and tracks your progress as you go.
