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. 4 Google Web Speech API Implementation :: Prajaks Jitngernmadan :: BUU

5. Introduction  Thai Characters  Shy  Modest  especially when it comes to English 5 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. 6 Google Web Speech API Implementation :: Prajaks Jitngernmadan :: BUU

7. Technologies  How to correct the answer  Text comparison method  Similar Text Algorithm 7 Google Web Speech API Implementation :: Prajaks Jitngernmadan :: BUU Input Answer :: user Given key :: admin similar_text()% similarity

8. Technologies  How to recognize the speech  Web Speech API   Google Chrome version 25+ 8 Google Web Speech API Implementation :: Prajaks Jitngernmadan :: BUU Input Speech :: user Google Web Speech API Output Text

9. System Design  Translating Practice Structure 9 Google Web Speech API Implementation :: Prajaks Jitngernmadan :: BUU answer Solve-1 Solve-2 Solve-3 Highest Score Calculate Input Compared by Similar Text select the best result wrong >= 80%? correct Threshold user no yes

10. System Design  Speaking Practice Structure 10 Google Web Speech API Implementation :: Prajaks Jitngernmadan :: BUU Web browser Chrome Google Server Text from voice Web Speech API (over Internet) Convert to text speak user Translating Process

11. System Design  Overall System Structure 11 Google Web Speech API Implementation :: Prajaks Jitngernmadan :: BUU Internet user admin Google Chrome 25+ Application Server Database

12. System Design  Database Design 12 Google Web Speech API Implementation :: Prajaks Jitngernmadan :: BUU

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

14. System Implementation  First Prototype Approach 14 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 15 Google Web Speech API Implementation :: Prajaks Jitngernmadan :: BUU

16.
