VocoLinggo

Real-time speech translation that runs fully offline. Your voice never leaves the phone — no account, no cloud upload, no ads.

Speak Anywhere, Understood Everywhere.

VocoLinggo turns your phone into a real-time, two-way speech translator — offline. Speak, and the other person hears it in their language; they reply, and you hear it in yours. No typing, no waiting, no internet required.

WHY VOCOLINGGO

• Fully offline — Speech recognition, translation, and voice synthesis all run on your device. Once the language pack is downloaded, it works with no signal at all: on a plane, underground, or roaming abroad without a data plan.

• Private by design — Your voice and conversations are processed entirely on-device. Nothing is uploaded to a server, there's no account to create, and nothing to log in to.

• Real-time — Live captions appear as you speak, with fast turnaround from voice to translated speech.

• Built for real conversations — A simple two-language layout ("their language" / "your language") made for face-to-face conversation, not just one-off phrase lookup.

LANGUAGES

Chinese, English, Japanese, and Korean work out of the box with no download. An optional language pack unlocks 30+ languages total, including French, German, Spanish, Italian, Russian, Portuguese, Arabic, Vietnamese, Hindi, Indonesian, Thai, Dutch, Polish, Turkish, and more.

CONVERSATION HISTORY

Every exchange is saved locally so you can look back at what was said and how it was translated — useful for travel, study, or work.

Optional Smart Glasses (Coming Soon)

Future versions of VocoLinggo are planned to support pairing with compatible smart glasses via Bluetooth for a hands‑free experience. This feature is an optional add‑on—all core translation functions work perfectly using just your phone’s microphone and speaker, with no external device required.

No ads. No in-app purchases. No account required.
