What is Vozi Grammar?
Vozi Grammar is HelloVozi's grammar coach: a guided conversational lesson that teaches you an English structure from the beginning and stays with you until you can use it when you speak. You practice by voice or by text, and every topic is open.
It works in three phases. First you learn the form and meaning on a dynamic whiteboard. Then you practice with adaptive support: if you make a mistake, Vozi says “Not yet” with a hint about the rule, without giving you the answer, and you can ask for a simpler explanation. Finally, you use the grammar in a real conversation, in a new context, where Vozi checks that you use it on your own.
Unlike a grammar checker, Vozi Grammar teaches first and uses correction as part of the path toward communication. Vozi speaks to you only in English, with shorter sentences and clear examples if you are just starting. At the end you see your result and a suggestion to review in two days.
How does Vozi Grammar teach English grammar?
It guides you through three phases: you learn the form and meaning on a dynamic whiteboard, practice with adaptive support and use the grammar in a real conversation where Vozi checks that you already use it on your own.

Learn the structure.
The board shows the formula, real examples and the affirmative, negative and question forms. Vozi's voice gives you the purpose and the key idea, without reading the board.
Before practicing, a quick check with two options.

Practice with support.
If you make a mistake, Vozi says “Not yet” with a hint about the rule, without giving you the answer, and you get another try. You can ask for a hint or a simpler explanation whenever you want.
If the second try does not work, you see the full correction and move on to a new task.

Use it in a real conversation.
Vozi changes the situation and talks with you about what you say. No answers in sight: that is how it checks you already use it on your own.
It comments on your ideas and asks one question at a time.

What matters before starting.
Does Vozi Grammar only correct mistakes?
No. It teaches first, adapts practice to the learner and uses correction as part of a scaffold that leads to independent communication.
What happens when a learner needs help?
Learners can ask for a hint or a simpler explanation. The coach offers only the support needed and then checks a new response.
How does grammar practice end?
It ends with a connected conversation in a new context. The learner must use the target grammar independently across several responses.
What are the three Vozi Grammar phases?
Learn the model, practice with adaptive support, and demonstrate the grammar in real conversation.
