Every word you dictate
coaches you back.
A dictation keyboard with a coach inside. It learns from the English you speak all day — standups, messages, notes — and turns it into fluency you can hear. Nothing to study.
You said
I will send it when I will finish.
More natural
“I’ll send it when I finish.”
One sentence, from spoken to fluent.
You already speak English for hours a day. Watch what Voco does with a single line of it — no lessons, no study session, just the speaking you were doing anyway.
You speak. Voco types.
Talk to the keyboard the way you’d talk to anyone — transcribed on-device, in real time, inside the app you’re already in.

Your words, exactly as you said them.
A normal message, fired off in standup. Nothing about your day changed — but every word just quietly became material.

Voco finds the one that matters.
From what you actually said, it surfaces a single natural rewrite — with the reason it’s better. Not a wall of red ink.
Review
1 moment worth a look
You said
“I will send you the doc when I will finish it.”
More natural
“I’ll send you the doc when I finish it.”
Why: after “when” for a future action, English uses the present tense — not “will.”
You say it back, and it sticks.
Hear the fluent version, repeat it, and watch your fluency climb. The fix lasts because the sentence was yours.
“I’ll send it when I finish.”
Nailed it ↑
Voco listens the way a great tutor would — across five dimensions at once. Two run fully on-device, no key needed. Three unlock with your own AI key.
Pronunciation
Per-sound scoring from forced alignment
Fluency
Fillers, pace & pauses from your audio
Grammar
Tense, articles, agreement in context
Word choice
More natural, native phrasing
Clarity
Conciseness, tone & register
One tool. Dictation on the surface,
a coach underneath.
A keyboard that types as fast as you think
Voco’s on-device keyboard works in every app — Slack, Mail, Notes, your editor. One continuous Flow Session keeps listening as you swipe back to your work. This is the part you’d install even if it never coached you.
- Parakeet & Whisper, running entirely on your phone
- Continuous flow — speak across apps without re-tapping
- Every word you dictate quietly becomes coaching material

A few real moments, said better
Not a wall of corrections. Voco curates a handful of genuine learnable moments from what you actually said — each with your line, a more natural version, and a one-line why. Wins are celebrated too, so it never feels like a report card.
- Your real sentence → the native rephrase → the reason
- Tagged by lens, mixed with wins you should keep doing
- Digestible by design — a 90-second daily habit, not homework

You used “circle back” naturally in standup — third time this week. It’s sticking. ✅
You said
“I will send you the doc when I will finish it.”
More natural
“I’ll send you the doc when I finish it.”
Why: after “when” for a future action, English uses the present tense — not “will.” You’ve done this 4× this week.
The invisible, made visible
Open any note and your transcript is layered with what your ear can’t catch on its own — sounds that need work tinted in, filler words flagged, long pauses marked, pace measured. Speech you can finally look at.
- Per-phoneme pronunciation scoring, computed on-device
- Fillers, pauses and pace surfaced right on the words
- Objective signals — measured, not guessed

Practice your sentences, not random drills
The fastest way to internalize a fix is to say it. Voco plays back the more-fluent version of something you genuinely tried to say, then you repeat it — and it re-scores you on the spot. No invented flashcards.
- Hear it spoken naturally, then say it yourself
- Re-scored live so you feel the improvement
- Built from your real lines — the anti-busywork
Shadowing · pronunciation
Say your own sentence,
the more fluent way.
“I’ll send you the doc when I finish it.”
Your turn — say it
Fluency you can watch compound
A weekly digest shows your fillers dropping, your sounds sharpening, your levels rising — per lens, with real deltas. Streaks and only-up levels keep you going. There’s no score that can fall and make you quit.
- Per-lens deltas: “Fillers 5.1 → 3.2 ↓38%”
- Recurring patterns tracked until they’re mastered wins
- Only-up levels & streaks — encouragement, never shame

How you’re improving
The coach that forgets nothing,
and sends nothing.
Voco only works if you talk to it all day. That bargain only makes sense if your speech stays yours. So it does.
Audio never leaves your phone
Transcription runs on-device with Parakeet and Whisper. Your voice — the most personal data there is — is processed locally and never uploaded.
Coaching is yours to switch on
The on-device coaching — pronunciation and fluency — runs locally and stays private, no key needed. Deeper AI review is opt-in and uses your own key, so the cost and the data path are yours.
No account to start
Install the keyboard and dictate. No sign-up wall, no profile harvested before you’ve typed a word. The Learner Profile that powers coaching stays on your device.
The same on-device dictation, in your menu bar
Hold a hotkey, speak, and Voco drops the text straight into whatever app you’re in. Fully local, built on the same engine — so the desktop where you write all day is covered too.

The things people ask first
No — Voco is built for people who already speak and work in English every day but want to sound more natural and fluent. If you’re in standups, writing PRs, and on calls in English, you’re exactly who it’s for.
Transcription and the core coaching (pronunciation, fluency) run entirely on-device — your audio never leaves your phone. Only the optional deeper review (grammar, word choice, clarity) calls an AI model, and only with your own key when you turn it on.
The advanced lenses run on a large language model. Instead of bundling that cost into a subscription, you connect your own API key, so you pay the model provider directly and your text goes straight to them — not through us. The on-device coaching needs no key at all.
Those are excellent dictation tools — and they stop at turning speech into text. Voco does that too, then keeps going: it learns from the English you dictate and coaches you to speak it better. Dictation is the doorway; coaching is the point.
Never. There’s no curriculum to keep up with. You just dictate as part of your normal day, and Voco surfaces a few worthwhile moments when you want them. Practice is optional and always built from your own real sentences.
