  3. Objectives • To design an automatic free-text answer correcting system architecture • To apply Google Web Speech API for speech recognition • To design and develop a simple online English training system prototype Google Web Speech API Implementation :: Prajaks Jitngernmadan :: BUU

  4. Introduction • Language is one of the key successful factors. • Multi-cultural society. • Common Language  English • AEC in 2015 • Most of Thais lack of English speaking and listening skill. Google Web Speech API Implementation :: Prajaks Jitngernmadan :: BUU

  5. Introduction • Thai Characters • Shy • Modest •  especially when it comes to English Google Web Speech API Implementation :: Prajaks Jitngernmadan :: BUU

  6. Introduction • The online English training system has to be • Supporting the users to practice translating and speaking skill with real-time feedback. • Easy to access  web-based. • Encouraging the users interactively. • Providing necessary information.

  13. System Implementation • First Prototype Approach Google Web Speech API Implementation :: Prajaks Jitngernmadan :: BUU

  14. System Implementation • First Prototype Approach Google Web Speech API Implementation :: Prajaks Jitngernmadan :: BUU

  15. Conclusion • Hands-on English system (English Skill Online Practice) • Web-based application • Designed and developed under the conceptual interaction and didactics • System gives the responses within a minute • for speaking, the response time depends on the Internet connection speed Google Web Speech API Implementation :: Prajaks Jitngernmadan :: BUU

  16. Conclusion • Future Works • Improve the answer correcting method • Redesign the user interface for more interactive and user-friendly • Test and collect data of learning improvement for statistical analysis • Acknowledgment • Faculty of Informatics at BuraphaUniversity • Computer Graphics and Multimedia Research Laboratory Google Web Speech API Implementation :: Prajaks Jitngernmadan :: BUU
