Duolingo, the acclaimed language learning app, announced two major new features at the recent virtual Duocon conference: Adventure Mode and AI Video Calls. This initiative marks a significant step for Duolingo in leveraging advanced technology to enhance the user learning experience. Duolingo co-founder and CEO Luis von Ahn stated, "Our mission is to develop the best education in the world and make it universally accessible. These innovations are just the beginning of what we aim to achieve."

Google has released its latest English tutoring tool aimed at competing with Duolingo. The tool will be gradually rolled out on Android devices across multiple countries. It offers personalized English speaking practice, grammar, and semantic feedback. Utilizing AI and machine learning technologies, the content is created with the help of linguists and teachers. Google plans to expand it to more countries and languages.

AI-powered language learning app Speak has secured $16 million in Series B funding. Investors include Lachy Groom, Drew Houston, and Arash Ferdowsi. Speak plans to expand its market and enter the U.S. market.
