Do you pronounce the word "human" as though it were spelled "yuman?"?

I’ve only heard a few people do this, and most of them were involved in academica—a few of my literature professors and some graduate students who seemed to be copying said professors.

My hasty research has indicated that this is a British thing, but I’m more interested in why people say this than in the origin of the pronunciation.

Did you adopt the “y” sound? Did someone teach you? Is it a conscious effort every time? Why do you pronounce “human” this way?

Just curious.
