Chapter 9: Personal reflection: This chapter provides a brief insight on researcher's own experiences, practices and observations as an insider. The chapter enables the reader to see through the researcher's lens. This chapter has used first person. Chapter 10: Conclusion: In addition to predicting the user acceptance, it provides an insight on the feasibility of such applications along with some suggestions that could be incorporated when designing and developing such applications. Finally, it enumerates the contribution to the knowledge and further work. * So what is your opinion/ experience, very specifically on pronunciation of the Brahmins and the non Brahmins?
