you’d better speak as loudly as possible and as clearly as possible if you need to speak English whether they are long sentences or only a few simple words during your speech.I think you can get more confidence and more respect and trust from our customers.Don’t forget that what we sell are not our products,we just sell respects and trusts.There must be several people who can speak English well among the listeners or may be all of them want to speak English fluently,so it’s a chance for you to get their respects and trusts.
