How does the way we speak , tell us about who we are ?

• I think we can get more informations in the persons accent . Because some country like Singapore have their own accent . Most of the Singaporeans speak singlish and other foreigner speak their own country language . When somebody speaks , we can identify some accent like singlish or China language . Singlish represent Singapore and I don't think other people in other country will speak singlish . So , we can tell who we are from the way the people speak and in their accent .
