How does this technology work?

ELSA uses proprietary speech technology with deep learning and AI to detect people's pronunciation mistakes with 95%+ accuracy. ELSA Speak listens to the way language learners pronounce words, sentences, or conversations to pinpoint exact errors and provide real-time feedback on pronunciation mistakes with specific suggestions on how to improve. ELSA can identify exact errors at individual sound levels, intonation, rhythm, and pitch, and provides instant feedback and recommendations on how to fix those errors. All feedback is fully automated using the proprietary speech recognition technology based on deep-learning algorithms.



What is unique about ELSA's voice recognition technology?

ELSA’s advantage lies in its proprietary voice recognition AI tech. The team at ELSA has collected the largest amount of accented English voice data from millions of users that they have used to train the AI model over the last few years. This in turn provides the app a higher accuracy in recognizing and understanding non-native English speakers around the world.
When it comes to the other existing voice recognition technologies available, they, might understand native speakers well but can possibly have a hard time understanding non-native accented English learner communities.

Instead of providing feedback about individual words, ELSA’s app also corrects individual sounds and gives users detailed information on how to improve their pronunciation, including advanced prosodic speaking features like intonation, rhythm, and fluency to help users speak English more naturally.



Our Take
With over 1600+ English lessons and a comprehensive pronunciation training curriculum that covers all sounds in American English, ELSA really has it figured out when it comes to language learning. Technology will be the go-to tool to solve real-world problems and education is a sector that will greatly benefit from the influx of AI.
