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

Democratizes Access to English Speaking & Training, Announces Partnerships with Edtech Institutions

ELSA, a company that uses speech recognition technology and artificial intelligence to help language 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 an English-speaking feature with automated speech recognition and interactive teaching. ELSA’s AI technology was built for the ELSA Speak App, which boasts 25+ million customers worldwide. With the release of its API, ELSA is democratizing the access to quality learning for users around the globe with 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-powered app that helps learners speak English more fluently. One of the differentiating attributes of its API is a focus on pronunciation, which can recognize non-native speech with +95% accuracy and design a pathway to native pronunciation. 

ELSA’s API provides detailed feedback for both scripted and unscripted speech with word stress, pronunciation, fluency, intonation of the audio input, grammar and vocabulary analysis. The learner also receives an estimated IELTS score/ CEFR level based on their speaking proficiency. Learners receive customized & interactive practice with the AI on any topic, offering a natural learning setting where any learner can benefit. Speech features are among the most engaging to learners; as shown through ELSA’s average session length of 23 minutes, in the top 10% of all learning apps.

Speaking on the announcement Vaibhav Anand, India Country Manager said, “Our proprietary voice recognition makes ELSA unique in terms of training based on voice recognition. In India itself, ELSA offers Bengali, Hindi, Punjabi, Telugu and Tamil as an option under ‘mother tongue’ to non-native English speakers. As a global brand, our endeavour is to build an ecosystem of learning where individuals can master spoken English and become confident with ELSA.”

“As English communication quickly evolves into a requirement for the modern skillset, it’s essential that edtech and learning companies include this competency in their curriculum. Students want digitized training and quality learning at their fingertips anytime, anywhere and the release of our API makes it available to a broader audience,” said Ms. Vu Van, Co-Founder and CEO of ELSA.

Accuracy of ELSA’s AI is highest in the market because ELSA possesses the largest audio dataset of non-native speakers, and its AI can adapt depending on the speaker’s mother tongue. The ELSA app has aggregated 25m+ users across 120+ countries and retains a 4.8 / 5 rating by 50,000+ users on the Apple App Store & Android Play Store. In 2022, it plans further expansion in Vietnam, Latin America, India, and Japan after a prosperous 2020 with a 300% increase in its 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 US and Kyoto University in Japan. ELSA plans to collaborate with more edtech companies to further enable language learning around the world.

In addition, ELSA is a strategic partner to Sahi.ai, an Indian staffing platform, to help its gig workforce enhance their English skills for better opportunities and wages. ELSA has also partnered with CNA Go, the largest English center chain in Brazil, and Edulinx, a leading TOEIC and corporate English education company in Japan, to enhance their digital platforms with speaking features.

According to research, teaching through combined senses (ie. auditory + visuals) fosters better long-term memory formation and better learning outcomes, especially in children. Leveraging on this understanding, POPS Kids, an interactive educational platform for Vietnamese children, integrated ELSA voice recognition technology into their English pronunciation practices. While watching cartoons, the young users can learn native pronunciation and interact with a fun AI tutor. Another edtech partner, UOLO, reported an engagement rate at 10-15x times of normal lessons when applying ELSA’s API in a gamifying renovation of its speaking module.
