ELSA is the world’s most advanced artificial intelligence tutor that helps people become conversational in English. ELSA is able to pinpoint a user’s pronunciation errors and provide real-time feedback on how to move one’s tongue or lips differently to correct the error. ELSA is able to precisely identify the vowels or consonants a user mispronounces, and if the user spoke with the right stress and intonation. To enable this functionality, we developed a proprietary speech recognition technology using deep learning. ELSA’s AI engine can precisely identify pronunciation errors because it learns from specific characteristics of a user’s native tongue as well as each individual’s speech acoustics. The more data ELSA collects from users in each region, the more accurate it becomes in identifying speech errors from other users in that region.

The more data ELSA collects from users in each region, the more accurate it becomes in identifying speech errors from other users in that region.

In March 2016, we debuted the ELSA Speak app at SXSWEdu and won first place at the competition. The results since then have been overwhelmingly positive. ELSA has had over 750,000 downloads by users from more than 120 countries, with zero marketing spend. The userbase has grown organically by 35% month over month. ELSA’s growth has been driven by word of mouth and teacher recommendations to students. A survey of 3,000 ELSA users showed that more than 60% of users found out about ELSA through friends, and another 15% found out about ELSA through their teachers’ recommendations.

ELSA’s users have been extremely engaged. They have completed over 40 million
exercises on ELSA’s platform. The user data we collect gives us a significant advantage as we train our deep learning AI model, making ELSA even more accurate in recognizing pronunciation errors for different accents

Users love ELSA. In the fall of 2016, a user who loved his experience on ELSA and
submitted ELSA to Product Hunt. Within less than 24 hours, ELSA was featured as the #1 Edtech app, with hundreds of upvotes and comments from active users around the world. On Apple’s App Store, ELSA has also been ranked #1 in the Education category and in New Apps We Love in over 25 countries in Europe. Users have left raving reviews on both Google Play Store and Apple App Store, with more than 8,000 reviews and an overall 4.7 star rating.
