In the southern US, French is spoken by a community of 500,000 people.
These are the Cajun people, descendants of French-speaking Canadians who were forced from their homes by the English in the 18th century.
Today they make up a tenth of Louisiana and their presence over the years have left a marked influence on the state.
These days, the Cajuns continue their traditions through music and song, which help them to keep their linguistic heritage alive.
