About us

ELSA (English Language Speech Assistant) is a startup founded in 2015 by Stanford alum Ms. Vu Van, and Dr. Xavier Anguera, a veteran in speech recognition and AI. ELSA’s app, which is called ELSA Speak, listens to the way language learners pronounce words, sentences or conversations to pinpoint exact errors and provide real-time, accurate feedback on their pronunciation mistakes with specific suggestions on how to improve. The company built its own proprietary speech technology using deep learning and A.I. to detect people’s pronunciation mistakes with 95%+ accuracy. Based in San Francisco, ELSA has raised $12 million in capital and is backed by leading VCs in Silicon Valley, Southeast Asia and Japan. ELSA Speak is available on iOS and Android with more than 40 million downloads in over 100 countries. The company has offices in Portugal, Vietnam, India, Indonesia and Japan.
