You know, the “fffffpppbbbtt!” sound made by sticking out your tongue and blowing, imitating a fart?
Sounds like it would be an unvoiced bilabial trill, but I’m not sure. A few languages use it. See Voiced bilabial trill - Wikipedia
You mean the venerable bi-labial fricative?
Not sure, outside of rude noises, which seem to be an universal language.
Ah! Wiki claims that it is:
I don’t think the voice bilabial fricative (a common phoneme in language such as Spanish and in Hindi) is the same as the raspberry.
I just tried a few raspberries sitting here, and I don’t seem to have vibrated my vocal cords in the process. So I would categorize the sound as unvoiced.
You should be able to voice it if you want. AFAIK, all fricatives and stops can be voiced or unvoiced.
[h] can’t really be voiced.
According to the wikipedia entry on the voiced glottal fricative, it does appear in English as well as in other languages.
God, linguistics makes me hot. Bi-labial fricative! man-swoon
As for the question, I’ll shoot my old psycholinguistics professor an e-mail and get back to you.
From the article:
It is a transitional state of the glottis. It has no manner of articulation other than its phonation type. Because there is no other constriction to produce friction in the vocal tract, most phoneticians no longer consider ɦ to be a fricative. True fricatives may have a murmured phonation in addition to producing friction elsewhere. However, the term “fricative” is generally retained for the historical reasons.
Emphasis mine.
On the other hand, more or less the exact same phrase appears in the article for the voiceless glottal fricative.
The conclusion being: I was wrong about there being no voiced equivalent, and I was wrong about [h] being a fricative.
And everyone knows, two wrongs make a left. Right?
A bilabial trill would be, though.
eta: Crap, skipped the second post which already explains this.
