Hi everyone. I have just read all the messages. I am a trainer too in the call center industry infact we are a team for soft kills and accent training. We have trained in accent training in fact we are currently training, I beleive u cannot change your accent completely but one needs to understand the difference in british and american accent and be able to adopt accordingly. In our training we train right from foundation differentiating british and american so that the candidate can understand the foundation and learn on his own rather than we spoonfeed the person for each and every word. We have tried it and we have got wonderfull results.
