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.

“Let’s put off the migration until we figure out the cause.”
Both are correct. Spoken aloud, postpone and determine read like a memo — most natives reach for the two-word verb.

“Let’s put off the migration until we figure out the cause.”
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.
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.
Sound
Per-phoneme pronunciation, scored on your own words
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.
The keys you never use, spent on you
You switched to Voco to speak, so the letters are the wrong default. The keyboard opens on a short standing sheet instead — a few lines pulled from your own recordings, each one something you’ll actually say next to the one move to make. Glance, speak, carry on. QWERTY is one tap away.
- A line earns its slot only if it’ll come up again soon
- Nothing shifts mid-session — a sheet to internalize, not a feed
- Beat a habit and it stays one more session, struck through

A few real patterns, worth your week
Not a wall of corrections. Voco watches what you actually say and surfaces one focus for the week — the pattern it keeps hearing, with the count behind it. Everything else waits in Browse patterns until it’s earned your attention.
- This week’s focus, drawn from your own recent notes
- Patterns grouped by lens: grammar, word choice, clarity, sound, fluency
- A five-minute practice session, not homework

Open any note and switch to Coaching: your transcript comes back layered with what your ear can’t catch on its own — the phrases worth fixing marked inline, long pauses shown, pace measured, with the audio right there to replay.
- Original, Cleaned and Coaching views of the same recording
- Pauses, pace and coaching moments surfaced right on the words
- Context → you said → suggested → why, for every moment

Note
Aug 3 at 01:49I think we should postpone the migration··· until we··· determine the root cause, and I think that’s probably the safer call anyway.
Coaching
Practice your sentences, not random drills
The fastest way to internalize a fix is to say it. Voco shows the line you actually said next to the more natural version, plays it for you, then listens while you say it back. No invented flashcards.
- Hear it spoken naturally, then say it yourself
- Listens live and stops on its own when you finish
- Built from your real lines — the anti-busywork
Say it more naturally

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
Levels only go up — nothing here can fall.
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.
Voco is on the App Store now for iPhone and iPad. It’s free to download, and the Coach comes with a 14-day free trial.
