Thanks Patsylabrador and Ajm200. Our handset must be quite old but I've now found the speaker button with '?' next to it which presumably turns it off on a daily basis. Now I know that it's called 'Audio Description' I turned it off on the main menu, so perhaps it will be off permanently tonight? Can't believe it was that simple, having put up with the irritation for months, last night was the final straw. Pity about the film; sure it will be repeated though.
