Voice Doubt Solving: Speak Your Question, Hear the Answer

Quick answer: Typing a chemistry equation on a phone keyboard is slow. Saying ‘why does sodium react violently with water’ takes three seconds. Voice makes doubt solving faster — and reading aloud makes revision easier.

How it works on DoubtPay AI

1. Open the study space, tap the mic (works in Chrome on phone and desktop).
2. Speak in Hindi, Hinglish, English or another supported language.
3. The question appears in the box; edit it if a word is wrong.
4. Choose the help type and get your answer.
5. Tap Listen to hear the explanation read aloud.

When voice is best

• Long conceptual questions (‘explain why…’).
• Students who type slowly or study in regional languages.
• Revising while walking — listen to yesterday’s answers.
• Younger students (Class 6–8) who find typing hard.

When to type or photograph instead

• Equations, chemical formulas, and anything with symbols — photograph it.
• Noisy rooms.

Tip

Say the class and chapter first: ‘Class 9 gravitation — why does a feather fall slower than a stone?’ Context improves the answer.
