Gemini Instant Voice Translation is an instant voice translation application powered by Google Gemini 2.5 Flash AI. Whether you're traveling abroad, attending an international conference, or communicating with foreign friends, this app helps you translate conversations instantly, making cross-language communication easy and natural.
This is also my second Vibe Code app. Initially, it was a Gemini web app, but I thought it would be very useful, so I exported it as Manus 1.6 and converted it into an installable app, which cost me 15,000 points. Theoretically, it should work with all languages in the world; you just need to enter your own API key.
Core Features
🌍 Supports 7 Languages for Translation: Easily switch between source and target languages, supporting translation between English, Japanese, Korean, German, French, Spanish, and Traditional Chinese. Whether you want to translate from English to Chinese or from Japanese to Korean, you can complete the setup with just a few clicks.
🎙️ Instant Voice Recognition: Employs advanced voice recognition technology to accurately capture your voice content. Simply speak into your phone, and the system will instantly convert your speech into text and display it on the screen.
🔊 Natural and Fluent AI Voice: Offers four different AI voice styles (Kore, Zephyr, Puck, Fenrir), each meticulously tuned for natural and fluent pronunciation, making the translation sound like a real person speaking.
📝 Translation History: All translated conversations are automatically saved in the history for easy review. No detail is missed, whether it's an important business conversation or a fun exchange during travel.
🔐 Privacy and Security: Your API Key is encrypted and stored using the device's built-in secure storage mechanism. All voice data is transmitted only during the translation process and is not stored on cloud servers. Your privacy and security are in your own hands.
🛠️ Debugging Log Function: A complete built-in logging system allows you to easily export log files for debugging or share them with the technical support team for assistance if you encounter any problems.
