There were a number of radio stations in communist countries which used defectors from the west to read out their tirades of propaganda. I remember Radio Tirana, which had a woman with a grating voice and a slight Scottish accent who used to read the 'news' in an unvarying monotone, of course it was not news at all, but a commentary liberally peppered with phrases such as the :
"The revanchist revisionist imperialist Zionist capitalist running dog lackeys of the West ........"
and every minute or so they referred to :
"Our revered and beloved leader Comrade Enver Hoxha".
I found a website which refers to it as :
The stultifying dull, Radio Tirana which used to broadcast hours of Marxist-Leninist propaganda night after night.

The site has a lot to interest anyone who was interested in SW Radio :
Cold War Radio
