Feedback on every word you actually said.
Upload a recording of an English class or conversation — Zoom, Cambly, Preply, a voice note. Voxhum isolates your voice, finds every grammar and vocabulary mistake with the exact minute, and turns each one into a review flashcard.
30 free minutes when you sign up. No card.
Coming soonYou talk for a full hour in class and leave with two corrections written down — the ones you could catch without losing the thread. The rest evaporates when the call ends. It's not a focus problem: nobody can hold a conversation and take notes at the same time.

Your voice is isolated
Voxhum separates the speakers and mutes the teacher. The feedback covers what you said — not the whole class.
The report arrives ready
A CEFR estimate, every mistake with its exact minute, stronger vocabulary alternatives, fluency metrics and an improvement plan.
A report about your English. Not English in general.
This is a real review, field by field. Scroll to walk through it.
First, where you stand.
A CEFR estimate computed from what you said in class — not from a multiple-choice test.
Every mistake, with a time and a place.
The sentence as you said it, the correction, a one-line explanation. The timestamp jumps to the exact moment — you hear yourself say it.
Words ready to level up.
Stronger alternatives for things you already know how to say — each with its CEFR level.
The numbers you can't feel while speaking.
Your pace against the native band, errors per 100 words — and an improvement plan for the next class.
Computed from your spontaneous speech — 4,312 words in this class.
Grammar
12 occurrences“I have went there two times last year.”
▸ 14:32→ I went there twice last year.
A defined time in the past (“last year”) takes the past simple, not the present perfect.
“She don't like to speak in meetings.”
▸ 21:07→ She doesn't like to speak in meetings.
Third person singular: “she” takes “doesn't”.
“I am working here since 2022.”
▸ 08:15→ I have been working here since 2022.
“Since” + a starting point takes the present perfect.
Vocabulary
6 suggestionsSays the same with more precision — and marks vocabulary above the basics.
Fluency
this classMost of them clustered in past simple vs. present perfect.
Every mistake becomes a flashcard.
Re-reading a correction once fixes nothing. Recalling it on demand, at growing intervals — 1 min, 6 min, 1 day, 4 days — does. Voxhum schedules that for you: every mistake from the review joins the queue, with your sentence as context.
