Van Dinh Hong Vu’s AI-based tool, Elsa, has revolutionized English language learning for over 50 million users worldwide. Recognized at the World Economic Forum, Elsa utilizes advanced AI for personalized feedback on pronunciation and communication skills. With features like Elsa AI and Speech Analyzer, users benefit from real-time coaching, bridging the gap in English education, especially in regions lacking resources.
In January, Van Dinh Hong Vu was acknowledged as a Technology Pioneer at the World Economic Forum in Davos, being one of 200 leading startup founders. Her AI-based English-learning tool, Elsa (English Language Speech Assistant), boasts more than 50 million global users, showcasing substantial growth over nearly a decade. Recently, Apple highlighted Elsa in its New Year 2025 features on Vietnam’s App Store, citing it as a key example of AI-enhanced education.
Elsa employs a custom-developed AI model that assesses pronunciation at the syllable level, providing precise feedback for improvement. Vu, despite being proficient in English during her academic years, faced communication barriers abroad due to limited access to native speakers. She states, “For this challenge, technology is the only solution,” emphasizing her vision for using technology to aid English learning.
Initially, in 2015, AI’s application in language education was limited. Vu’s team began by considering Google’s speech recognition API but found it inadequate for pronunciation training. Subsequently, they collaborated with Dr. Xavier Anguera to create a proprietary system capable of recognizing subtle pronunciation errors with over 95% accuracy. This led to the development of Speech Analyzer, which provides real-time feedback.
As generative AI gained prevalence in late 2022, they introduced Elsa AI, allowing personalized simulated conversations. Vu explains, “Learners can practice real-life dialogues tailored to their specific needs, whether for work or daily life.” This feature enables users to engage naturally, facilitating conversations in both English and their native languages.
The AI tutor ensures instant feedback on grammar, vocabulary, pronunciation, and fluency, fostering skill enhancement. Vu points out that the app provides one-on-one tutoring access, addressing the scarcity of English teachers and offering an adaptable learning experience. Originally, Vietnamese users constituted a significant portion of the platform’s audience, but its reach has broadened internationally.
By 2024, Elsa had been downloaded in 195 countries with over 50 million users. It gained acclaim in 2017 when Forbes recognized it as one of four AI-driven companies revolutionizing the world. Vu believes the perception of AI has evolved; users now see it as a tool for efficiency in education and workplaces.
As generative AI advances, Vu envisions language-learning apps becoming increasingly adaptive. The company aims to create an AI tool that empowers users to communicate confidently across various settings. “Each learner will have a customized journey that integrates English learning with other essential skills,” she concludes, highlighting her commitment to continual innovation in language education.
Elsa, an AI-driven English-learning tool led by Van Dinh Hong Vu, is transforming language education for over 50 million global users. From its inception, it has successfully integrated advanced AI technology to provide personalized feedback and real-time learning experiences. The platform’s growth and recognition underscore its significant role in making language education more accessible and efficient, ensuring learners receive tailored support for their individual needs.
