Voice-Driven Language Practice Widget

An interactive educational plugin designed to enhance pronunciation and comprehension skills through voice-enabled learning.
Voice-Driven Language Practice Widget

Background

Language learning has shifted online, creating a need for solutions that engage learners and address pronunciation and comprehension challenges. Traditional platforms often lack interactive features, limiting speaking practice and immediate personalized feedback. So we developed an interactive, voice-driven widget integrated directly into existing e-learning systems.

Challenge

The main challenge was creating an intuitive and scalable solution that could seamlessly integrate into existing educational platforms while providing accurate, real-time feedback on language pronunciation. It required combining precise speech recognition with advanced linguistic processing to deliver immediate and actionable results. Ensuring the widget was accurate and responsive enough to sustain learner engagement posed a significant technical hurdle.
Tailored Tech Solutions

Solution

Development began with designing a JavaScript widget for seamless frontend integration directly into e-learning platforms. Using Google’s Voice-to-Text API, the widget captures and transcribes user speech in real-time. Transcribed data is then processed by OpenAI's ChatGPT API, which normalizes and formats the transcription, accurately handling complex cases like numeric expressions and subtle pronunciation variations. The final outputs are type-cast into structured data formats to enable reliable accuracy scoring and adaptive feedback tailored to individual learning curves.
