The application, Elsa, which stands for English Language Speech Assistant, functions as a personal coach to help English learners around the world speak English more correctly and confidently.
Elsa was established in 2015 by two Vietnamese, Van Dinh Hong Vu and Ngo Thuy Ngoc Tu, along with Xavier Anguera, a speech expert from Spain.
The competition is a part of the SXSW (South by South West) event, which is considered the biggest event in the United States for the creative industry.
FPT Ventures and two other personal investors had funded Elsa. The application is now available on Android and iOS.
