Usage of potential form of かける


In the sentence

> 男に突然声をかけられた  
>  駅までの道を知りたいらしい

I interpret this to mean "I yelled at the man so loud as if I wanted it to
reach all the way to the station"

Is my translation correct? Why is the potential form of かける used?




It's not the potential form, it's the passive form (which takes the same
structure).

> I/he was suddenly approached by a man (called at) ....

On a different point, as the first half the sentence the second half should be
too. (The sentence is still otherwise somewhat unnatural though)

> 男に突然声をかけられた 駅までの道を知りた **かった** らしい
