More from the BBC adaptation of Charles Dickens' Bleak House.
I've noticed in these sort of movies, when some very upper-class speakers talk, like the lawyer in the series, Mr. Tulkinghorn, they have a distinct way of pronouncing "wh" in what and when; the "wh-" sounds seems to be prefaced with an almost sharp whistling "h", so that it sounds like they are really saying hwat and hwhen.
I'd like to know three things: First, what is the specific name of this phoneme, as would be given by linguists? Secondly, what's the difference in articulation, in terms of tongues and throats, between this hwh- and wh-? And finally, the most difficult question of all: Is the hwhat these upper-class speakers produce a direct-line preservation of Anglo-Saxon pronunciation, through these many centuries? [I ask because I have seen the construction "hwæt hwæt" used playfully as an example of Anglo-Saxon speech, and figured that the "hw-" sound must have prominent in that language.]
