Travellers are being given free CDs telling them what to do if they feel harassed or discriminated against.
A travellers' site has existed near Cottenham for more than 40 years
The £10,000 scheme is being launched by the police in the Fenlands in Cambs, which has the biggest concentration of gipsy families in the country.
Cambs Police hope it will encourage more travellers to report incidents of racial discrimination.
The audio CD is called Del Gavvers Pukker Cheerus, a Romany phrase meaning "give the police a chance".
It was funded from Home Office money given to each police force to tackle race crimes.
'Break down barriers'
Some 2,000 copies of the disc are being distributed to travellers in the Fenland area.
A further 500 are being given to Cambridgeshire officers to make them aware of its contents.
It is the first scheme of its kind but other police forces are already interested in distributing copies.
Cambridgeshire Police hate crime manager Sgt Vic Galpin said: "People see a lot of negative publicity about travellers and very little about their plight.
"We are trying to address this and break down some barriers."
The CD is narrated by Romany journalist Jake Bowers and there are also comments and interviews with a series of travellers - giving their experiences of racism from members of the public.
Those listening to the CD are encouraged to contact police and the Independent Police Complaints Commission if they experience harassment from other members of the public or police officers.
