What?! Keep your dentos off my labios, Mister!

Neither

It's "bi-labial fricative". Ya just can't get a decent fricative off the teeth.

So how do you classify [f] and [v]?

[bookly.livejournal.com]

In case anyone is curious, Google returns the following results:

labio-dental fricative 559
dento-labial fricative 1
dental-labial fricative 0 (it offers this as a choice, but the words turn out to not be joined)

I suppose a fricative articulated using the top lip and bottom teeth might be called a dento-labial fricative, but I don't know of any languages that use that sound. :)

Why do you ask?

[cattitude.livejournal.com]

Which labia would that be? And doesn't it hurt if you go too heavy on the dento?

[maedbh7.livejournal.com]

For future reference, it is "labiodental" (no hyphen). Google returns 7,560 hits. -H (amateur linguist at large)...

No. The subject of my question was labiodental fricatives. (Leaving The Bonzo Dog Doo-Dah Band out of the discussion.)

[b] and [p] bilabial plosives.
[v] and [f] are labiodental fricatives.
[th] is a different (linguodental?) fricative.

I honestly can't work out what the mechanics of a bilabial fricative would be, however, they do exist:

Voiceless bilabial fricative

From Wikipedia, the free encyclopedia.

The voiceless bilabial fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is Φ, and the equivalent X-SAMPA symbol is p\.

Features of this consonant:

Its manner of articulation is fricative, which means it is produced by constricting air flow through a narrow channel at the place of articulation, causing turbulence.
Its place of articulation is bilabial which means it is articulated with both lips,
Its phonation type is voiceless, which means it is produced without vibrations of the vocal cords.
It is an oral consonant, which means air is allowed to escape through the mouth.
It is a central consonant, which means it is produced by allowing the airstream to flow over the center of the tongue, rather than the sides.
The airstream mechanism is pulmonic egressive, which means it is articulated by pushing air out of the lungs and through the vocal tract, rather than from the glottis or the mouth.

This sound doesn't seem to exist in english...the example on http://en.wikipedia.org/wiki/Bilabial_consonant is japanese (voiceless) - ([ɸuʝisaɴ]
富士山 Fujisan (="Mount Fuji"), but I can't figure out how to pronounce that initial f bilabially; and dutch (voiced) - [βaaɾ] waar (="authentic")

Unless, of course, you play a brass instrument, in which case no other sound exists.

Sorry. It's my mother who's the speech therapist. The only use I ever had for fricatives was in the context of playing the trombone. And in that case, you could never get a decent fricative off the teeth.

Ouch. Good point. I wonder how many points my soon-to-be-phonetics teacher would have docked for that. I have to confess that I probably wouldn't have noticed if one of my students had used the hyphen. :S

Re: Neither

"th" is an interdental fricative. The IPA symbol is a theta.

You're correct that the bilabial fricative doesn't exist in English, but if you remind me next time I see you, I'll try to give you a demonstration (but I'm sure you can find someone local to give you one earlier, if you need it).

how's the weather up there?

[miss-chance.livejournal.com]

Awww, now I'm embarrassed. Everyone is being so scholarly about it, and here I honestly though you were talking about something like a tongue-piercing that as tulpaspin so nicely put it, "increases the coefficient of friction." I can be so low-brow some days.
