Not knowing what language you are in go into setup and there should be an icon of lips with a speech balloon over it. Change it to a British English and voice. they are on the same options. Reason for British English is that it will be in two words such as Anglais Angleterre or Anglais UK in French or similar in other languages.. There should also be an Anglais US.
You cannot do damage if you pick the wrong language such as Zulu. Just more frustration.
