Speaking is one of the hardest parts of learning a new language, especially if you don’t have someone to practice with regularly. ELSA is an app that helps by using speech recognition technology to correct pronunciation. Based in San Francisco and Ho Chi Minh City, ELSA announced today it has raised a $15 million Series B, led by VI (Vietnam Investments) Group and SIG. Other participants included returning investors Google’s AI-focused fund Gradient Ventures, SOSV and Monk’s Hill Ventures, along with Endeavor Catalyst, Globant Ventures and U2’s The Edge (David Evans).

The capital will be used to expand ELSA’s operations in Latin America and build a scalable B2B platform, allowing companies and educational organizations to offers the app’s coaching services to employees or students. Founded in 2015, ELSA, which stands for English Language Speech Assistant, now claims more than 13 million users. Its last round of funding was a $7 million Series A announced in 2019.
