Can you tell me about call center training on voice and accent, spoken English for call center,BPO and public speaking?

These days, the advice is for a good accent. Even if you aren't grammatical, it's not a big problem. But, your English should sound English. I feel that you have to train yourself for about 2,3 months. Practice Phonetic Symbols first and then Stress, for all important words. Practice speaking slowly
