The Challenge

Chinese international students and expats in Canada were struggling with English fluency in real-world settings — classrooms, workplaces, and social environments. Traditional language apps focused on vocabulary, but not on the speaking and pronunciation confidence needed for daily life in an English-speaking country.

⚙️

The Solution

We built Mocka Rocka — an AI-driven web platform that trains English fluency through speaking and reading exercises tailored for Chinese learners. The AI evaluates pronunciation accuracy, comprehension, and speaking pace in real time, then delivers personalized feedback and tracks improvement across sessions.

  • AI-powered pronunciation evaluation with phoneme-level accuracy scoring
  • Speaking and reading exercises adapted to Chinese-English language patterns
  • Real-time feedback on fluency, pacing, and common Mandarin-influenced errors
  • Comprehension assessment with scenario-based reading passages
  • Progress tracking with session history and improvement graphs
  • Culturally relevant content reflecting Canadian daily life contexts
