Voice mode is live on the AI tutor

Schools we work with have been asking about the AI tutor experience that lets students talk to the AI through headphones and have it talk back — the same hands-free conversational style as Khanmigo. As of today, every lesson on LearningBro has it.

Open any lesson, scroll to the bottom, and tap Ask a question about this lesson. You'll see two new controls inside the chat panel:

• A microphone button next to Send. Tap it to speak your question — the chat will transcribe what you say in real time. Tap it again to stop, or just stop talking and it will pick up your sentence on its own.
• A Read aloud link under each AI reply. Tap it to have the answer spoken back to you. There's also an Auto-read toggle in the header — flip it on and every reply gets read out automatically, so you can keep your eyes on the lesson page or work through a problem hands-free.

How it works under the hood

We use the browser's built-in speech APIs — the same ones that power dictation in your browser's address bar and read-aloud features in many websites. That means:

• Nothing is sent to a third-party voice service. Speech-to-text happens in your browser; the transcript goes to the AI tutor exactly as if you'd typed it. Your audio doesn't leave the device.
• No extra cost is added on top of the AI usage you already have. Voice is free in the same way the type-to-chat tutor is included in your subscription.
• It works offline-ish. Browser speech-to-text needs a connection because the browser itself relays the audio to a recognition service, but it doesn't go through us. Speech-to-speech happens entirely on-device in modern browsers.

It's available in any browser that supports the Web Speech API, which is essentially Chrome, Edge, and Safari on desktop, Android, and iOS. Firefox doesn't support it on desktop yet — Firefox students will see the chat exactly as before, with no mic button or read-aloud link. Everyone else gets the new controls automatically.

When voice helps most

We've watched students use it for a few weeks during testing, and the most common patterns are:

• Walking back over a worked example without losing your place. You're following a chemistry mechanism or a maths derivation in the lesson, hit a step you don't follow, and want to ask "why does the bromine attack the carbocation here?" without scrolling away to type. Tap the mic, ask, listen to the answer, keep reading.
• Revising on the move. Headphones in, lesson open on a phone, walking to school or sitting on the bus. Auto-read on, the AI walks you through the lesson back-and-forth as you go.
• Accessibility. Students with dyslexia, motor difficulties, or reading fatigue can lean on voice rather than the keyboard. The tutor responds the same way regardless of how the question came in.

What it doesn't do

It doesn't do the thinking for you. The AI tutor still refuses to write your homework, your essays, or your coursework — voice mode just changes the input method, not the rules. It still asks Socratic questions, points you back to the lesson content, and refuses to hand over the answer to a quiz question.

It also doesn't replace the lesson. The voice tutor is scoped to the specific lesson you're on. Ask it about an unrelated topic and it will redirect you back to what you're studying.

Try it

Pick any lesson on the site — for example, Edexcel A-Level Chemistry: Ionic Bonding or Edexcel A-Level Maths: Surds and Indices — open the lesson, scroll to the AI tutor, and tap the mic. You'll need to grant microphone permission the first time; the prompt comes from your browser, not from us.

If your school is exploring AI tutoring tools and weighing options, this is the feature that closes the gap with Khanmigo for the chat experience — at no additional cost, on top of every course we've built (over 800 of them) rather than the smaller subset Khan Academy offers in the UK curriculum.
