About English AI Pronunciation Trainer
🗣️ English AI Pronunciation Trainer — by TonePerfect.app
Find out which English sounds give your accent away. Select any English text on a web page, right-click, and the trainer scores every word and every sound you say — th, r and l, short and long vowels — and tells you exactly which one to fix first.
No retyping, no copy-pasting: highlight, right-click, speak.
▶ WHY PRACTISE IN YOUR BROWSER
You read English all day — articles, emails, documentation, social media. Every one of those sentences can be a pronunciation drill. Most apps only say "try again". This one shows what went wrong, sound by sound:
✓ AI pronunciation assessment with an overall score from 0 to 100
✓ A score for every word in the sentence
✓ A score for every sound inside each word, written in IPA
✓ The weakest sound named for you, so you know what to practise next
✓ The reference pronunciation one tap away
🚀 HOW IT WORKS (3 STEPS)
1. Pin the extension to your toolbar.
2. Highlight any English text — a word, a phrase or a whole sentence.
3. Right-click and choose "Practice pronunciation on TonePerfect".
The text opens on toneperfect.app ready to record. Read it aloud, get instant AI feedback, repeat. That is the whole practice loop.
📌 WHAT IT DOES
➤ Right-click selected English text on any website and practise it in one click.
➤ Popup with quick minimal-pair drills for the classic traps: ship / sheep, think / sink, right / light, bat / bet.
➤ A text box in the popup: type anything — a tongue twister, a presentation line, your own name — and practise it.
➤ Per-word and per-sound scores, so "your accent" becomes a short list of sounds to work on.
🎯 THE SOUNDS LEARNERS STRUGGLE WITH — AND THE AI CHECKS
▸ th (θ, ð) — "think" vs "sink", "this" vs "dis"
▸ r and l — "right" vs "light", "rice" vs "lice"
▸ Short vs long vowels — "ship" vs "sheep", "full" vs "fool"
▸ æ vs ɛ — "bat" vs "bet", "man" vs "men"
▸ v and w, final consonants, consonant clusters ("months", "sixths")
▸ Dropped or added sounds at the ends of words
Every drill leaves you with measurable feedback, not vibes.
