Leading English Language Proficiency App ELSA Releases Speech Recognition and Feedback Engine API Availability | News

SAN FRANCISCO, Calif.; BANGALORE, India; TOKYO; Jakarta, Indonesia; SAO PAULO, January 25, 2022 /PRNewswire-PRWeb/ — ELSA, a company that uses speech recognition technology and artificial intelligence to help learners improve their spoken English, today announces the availability of its proprietary AI-enabled API. This API technology integrates into any language learning solution to develop English speaking functionality with automated speech recognition and interactive teaching. ELSA’s AI technology was designed for the ELSA Speak app, which has more than 20 million customers worldwide. With the release of its API, ELSA democratizes access to quality learning for users around the world thanks to new edtech partnerships with CNA Go in Brazil, Edulinx in Japan and Sahi.ai and UOLO in India, to name a few.

ELSA (English Language Speech Assistant) is an AI-based application that helps learners speak English more fluently. One of the differentiating attributes of its API is its focus on pronunciation, which can recognize non-native speech with +95% accuracy and craft a pathway to native pronunciation. ELSA’s API provides detailed feedback for scripted and unscripted speech with word stress, pronunciation, fluency, intonation of audio input, grammar, and vocabulary analysis. The student also receives an estimate of the IELTS / CEFR level score based on their oral proficiency. Students receive personalized, interactive practice with AI on any topic, providing a natural learning environment that any learner can benefit from. The voice functions are among the most interesting for learners; as shown by ELSA’s average session length of 23 minutes, in the top 10% of all learning apps.

“As communicating in English is rapidly evolving to become a requirement for modern skills, it is essential that education and learning technology companies include this skill in their curriculum. Students want digital training and learning quality at your fingertips anytime, anywhere and publishing our API makes it available to a wider audience,” said Ms. Saw Van, co-founder and CEO of ELSA.

ELSA’s AI accuracy is the highest on the market because ELSA has the largest audio dataset of non-native speakers, and its AI can adapt based on the speaker’s native language. ELSA app has amassed over 20 million users in over 120 countries and maintains a rating of 4.8/5 by over 50,000 users on the Apple App Store and Android Play Store. In 2021, he plans further expansion in Vietnam, Latin America, India, and Japan after a successful 2020 with a 300% increase in revenue. ELSA already works with an impressive list of clients like Singapore Airlines, AstraZeneca, Bosch, Intel, HCL and Siemens and institutions like rice university in the USA, Kyoto University in Japan, and British Council, one of the owners of the standardized IELTS test. ELSA plans to collaborate with more edtech companies to enable more language learning around the world.

In addition, ELSA is a strategic partner of Sahi.ai, an Indian recruitment platform, to help its employees improve their English skills for better opportunities and higher salaries. ELSA has also partnered with CNA Go, the UK’s largest chain of centers in Brazil, and Edulinx, a leading company in the field of TOEIC and teaching English in business Japan, to enrich their digital platforms with meaningful features.

According to research, teaching through the combined senses (i.e. auditory + visual) promotes better long-term memory formation and better learning outcomes, especially in children. Building on this understanding, POPS Kids, an interactive educational platform for Vietnamese children, has incorporated ELSA speech recognition technology into their English pronunciation practices. While watching cartoons, young users can learn native pronunciation and interact with a fun artificial intelligence tutor. Another edtech partner, UOLO, reported a 10-15x higher engagement rate than normal lessons when applying ELSA’s API in a playful revamp of its chat pod.
