Add AI Voice Over to YouTube Videos — 100% Free

You don't need to pay $20/month for AI voice over tools. Modern browsers have built-in speech synthesis that works for Hindi, English, and 100+ languages.

The Problem

Video creators spend hours recording voice overs. Freelance voice actors cost ₹500-₹2000 per video. AI voice services charge $10-30/month.

The Free Solution

Your browser already has a Text-to-Speech engine built in. I built a free tool around it: voiceaisaas.fun

How to Use It for YouTube

Step 1: Write your script in Hindi or English (or Hinglish mix)

Step 2: Go to voiceaisaas.fun and paste your script

Step 3: Click play and record your screen using OBS or Windows Game Bar (Win+G)

Step 4: Sync the audio with your video in your editor

Why This Works

The Web Speech API is built into:

Google Chrome
Microsoft Edge
Firefox
Safari

No downloads. No signups. No subscriptions.

For Video Creators

We also offer a ₹49 lifetime deal (500 credits) for premium voices and priority access. That's less than a single cup of coffee — for life.

Real Example

<button onclick="speak()">Play Voice Over</button>
<script>
function speak() {
  const msg = new SpeechSynthesisUtterance(
    'Namaste dosto, aaj hum seekhenge kaise free AI voice over use karein'
  );
  msg.lang = 'hi-IN';
  msg.rate = 0.9;
  speechSynthesis.speak(msg);
}
</script>
