Why Tune

Understanding English is not the same as being understood

Most apps check whether you picked the right word, not how you said it, so the accent you started with is the one you keep.

You freeze when it is time to speak

Reading and listening grow fast. Speaking needs reps out loud, and a class gives you a few minutes a week.

You cannot hear your own mistakes

“Think” turns into “sink” and “we” into “ve”, and nobody tells you. Without feedback, practice repeats the error.

Teachers cannot listen to every take

Checking pronunciation one learner at a time does not scale, so it is the first thing a course drops.

Tune closes the loop in under a minute

  1. Listena natural voice or a real video
  2. Speakalong with it, after it, or on your own
  3. Seeevery sound and word scored
  4. Fixwith the coach’s notes, then try again

Interactive demo

Tap a word to see what Tune heard

This is how a result looks after one take. Each word is coloured by its score; tap it to see each sound, what it sounded like, and how to fix it.

  • 90 and above: clear and close to the reference
  • 75–89: understood, with an accent
  • Below 75: worth another try

Sample data. In the app, scores come from your own recording.

Four ways to practise

Real English, not textbook dialogues

Practise with what you actually need to say: the talk you watched, the interview you are preparing for, the words you keep stumbling on.

Shadowing

Topics with texts read by a natural voice. Write your own or generate one at your level, from A1 to C2, then speak along, after it, or alone.

TogetherAfterRead

YouTube

Paste a link to a video up to 20 minutes. Tune transcribes it, cuts it into even segments, and highlights each word as the speaker says it.

Any speakerWord highlighting

Words

Drill the words that trip you up, one by one, with a reference voice. Any word from a result goes to “My words” in one tap.

Sound by soundMy words

Q&A

Questions on your topic, such as a job interview. Answer in your own words: Tune transcribes you, scores the pronunciation, reviews grammar and naturalness, and checks the content.

Free speechSample answers

Feedback

Deeper than a single score

Every sound

Scores for each phoneme, and the sound Tune heard instead, so you know exactly what to change.

Fluency and intonation

Rhythm, pauses, and melody scored beside accuracy, where the speech service supports it.

Reference, then you

Play each sentence by the reference voice and then by you, cut from your own recording.

A coach that listens

An audio AI model listens to your take and writes a short note in English or Russian, and can read it aloud.

Honest bands

Green starts at 90, not at “understood”: Tune grades more strictly than the speech service itself.

Visible progress

Try the same text again and see how much your score grew since the last take.

A daily speaking goal

Minutes you actually spoke, not minutes the app was open, with a small celebration when you hit the goal.

Made for the phone

Installs to the iPhone home screen from Safari. Practise on the go, with or without headphones.

For investors

A working product with the economics built in

Tune is past the prototype: it runs in production as a private beta, and every paid AI call is metered against per-user budgets.

4exercise types in one app
A1–C2levels steer every generated text
90 sper take, scored sound by sound
200+automated tests guard each release

Unit economics under control

Every paid call to a speech or language model is reserved and settled in a ledger, with daily and monthly budgets per user and a shared cap.

Provider-independent AI

Assessment, transcription, speech, and text models sit behind contracts. Text and speech models are switched in settings as prices and quality change, and another provider plugs in without touching the rest of the app.

Private by design

No public sign-up, recordings visible only to their owner, provider keys only on the server, and a security log of sign-ins and changes.

Mobile-first, no app store

An installable web app tuned for Safari on iPhone: microphone, playback, and interruptions handled where most learners practise.

FAQ

Questions, answered

How is Tune different from other language apps?

Most apps check what you chose or typed. Tune listens to how you sound: it scores every sound, word, and sentence of your own recording and tells you what to change. You practise with real speech, such as videos and texts on your topics, rather than tapping answers.

How accurate are the scores?

Tune uses a professional pronunciation-assessment service and stricter bands than usual: green starts at 90, so an accented word does not look finished. It is a practice tool, not an exam certificate. When a score is not available, Tune says so instead of guessing.

Do I need an iPhone?

Tune is designed first for Safari on iPhone and installs to the home screen. It also opens in current desktop browsers.

Which accent does it teach?

Reference voices speak American or British English. With YouTube you can shadow any speaker you like.

What happens to my recordings?

They belong to your account and only you can play them. You can delete any recording. To score and review a take, its audio is processed by our speech and AI providers. The privacy policy has the details.

Can I use my own material?

Yes. Paste a YouTube link or your own text, generate a text on any topic at your level, or keep a list of words you want to say better.

Why is it invite-only?

During the beta we add people in small groups to keep quality high and costs predictable. Leave a request and we will get in touch.

Can my school or company use Tune?

Yes. An administrator issues accounts, shares materials with every learner, and sets spending limits. Write to us about a pilot.
