Say it out loud. Find out exactly what to fix. SpeakZilla listens while you read a sentence and scores every word separately, so instead of a single number you can do nothing with, you see which sounds landed and which need another go. HOW IT WORKS The sentence plays in your coach's voice, slowly enough to hear where one word ends and the next begins. You read it back. Every word comes back coloured — green for clear, orange for close, red for another try — and the words you skipped are named rather than quietly ignored. WHAT MAKES IT DIFFERENT • Scored on pronunciation alone. Not fluency, not speed. A score that congratulates everyone teaches nothing, so this one is deliberately strict. • A coach, not a robot. Alex is British, Sofia is American, and one of them records every sentence and every word in the app. Pick the one you would rather sound like; neither is more correct. • A tip written for the sentence in front of you. Not "practise the /æ/ sound", but which words in this sentence carry it and what to do with your jaw. • A Sound Map of forty English sounds, coloured by how well you say each one, with drills for the ones you find hard. • Lessons that come back. Sounds you keep missing return on a schedule, so practice lands where it is needed rather than where you left off. HOW IT IS PACED Three new lessons a day, and your first ten are uncapped while you settle in. Anything you have finished can be replayed as often as you like, and sound drills never count against the limit. Practising a little every day beats one long session a fortnight, and the app is built around that rather than around how long you can be kept in it. Streaks, daily missions and eggs mark the days you turn up. Eggs are earned by practising and buy extra lessons — they cannot be bought with money. FROM FIRST WORDS TO NEAR-NATIVE A short placement test finds your level, then 120 lessons run from single short vowels to the contractions and reductions that make speech sound spoken. Level checkpoints confirm you are ready before the next one opens. From Intermediate up, each level closes with a short passage read in one take — where the linking and rhythm that single sentences cannot teach finally get practised. WHAT IT COSTS Nothing. No adverts, no subscription, no purchases. WHAT WE DO WITH YOUR VOICE Speech is scored as you speak and is not kept as audio. You can delete your account, your progress and everything stored with it from inside the app, at any time, without asking anyone. Made by one person who wanted to be understood the first time.
