Google has updated its Translate app on Android to improve translations of slang and local expressions using its AI, Gemini. The app now features "streaks" in practice sessions to encourage user engagement and is expanding a beta feature for real-time translations via headphones. This update, announced on December 12, enhances the accuracy of idiomatic translations and introduces a "Live Translate" button for easy access. The feature supports over 70 languages and is rolling out in the U.S., Mexico, and India, with broader availability expected by 2026. Additionally, users can assess their proficiency and receive tailored daily goals through new challenges in the app.
