WhatsApp Live Translation & AI Call Subtitles

Over 2 billion people use WhatsApp, and for many of them language is the main barrier on calls. WhatsApp live translation lets you follow any call in your language — the AI captures audio in real time and shows captions and translation directly on your Windows screen.

How to add live translation to WhatsApp in 3 steps

1. Download Live Subtitles from the Microsoft Store and launch the app.
2. Select "System Audio" — the app captures the caller's voice from your speakers.
3. Make or answer a WhatsApp call — real-time captions appear above the WhatsApp window automatically.

Why WhatsApp calls need real-time translation

WhatsApp Desktop on Windows has no built-in live captions or translation. For calls with family abroad, international clients, or multilingual customer support teams, missing a single word can mean a misunderstood agreement or a frustrated caller. AI live captions close this gap without any change to how WhatsApp works.

• Family calls across language barriers — understand relatives who speak a different language.
• International business calls — follow clients and suppliers without slowing down to ask for repeats.
• Customer support in multiple languages — agents follow any language call with captions.
• Calls with accented or fast speech — captions give a second channel to confirm what was said.

Dual subtitles: original language + translation simultaneously

Live Subtitles supports dual subtitle mode. The top line shows the original speech transcribed in the caller's language. The bottom line shows your chosen translation in real time. Both lines update simultaneously, so you follow both the exact words and their meaning without any delay.

This is especially useful when you're learning a language and want to check your comprehension, or when you need to communicate with a contact who speaks only one language while you speak another.

Works with WhatsApp voice and video calls

Live Subtitles uses system audio capture, which means it works with any audio that comes through your Windows speakers:

• WhatsApp Desktop voice calls
• WhatsApp Desktop video calls
• WhatsApp Web calls (in a browser)
• WhatsApp voice messages played back

No WhatsApp plugin, no API access, no permissions inside WhatsApp. The caller sees nothing different on their end.

50+ languages for WhatsApp calls

Live Subtitles supports over 50 recognition languages including Spanish, Arabic, Hindi, Portuguese, French, German, Italian, Russian, Japanese, Korean, Chinese, Turkish, Polish, Dutch, Ukrainian, and more. Translation target languages cover the same range. Select any combination — Spanish → English, Arabic → French, Hindi → Spanish — and the dual subtitle overlay works immediately.
