Features
Features of the voiceless bilabial fricative:
- 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 middle 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.
In English
This consonant is lacking in English, and English speakers will often pronounce voiceless labiodental fricative when speaking a language that has it, while speakers of a language that has it may use it in place of English 'f'. English speakers, however, may consider this consonant similar to a simple blow, but with a much narrower opening between the lips.
In other languages
Ewe
Ewe contrasts bilabial Template:IPA, written ƒ, with labiodental /f/, written f, as in é ƒá Template:IPA "he polished" vs. é fá Template:IPA "he is cold".
Japanese
Japanese has Template:IPA an allophone of Template:IPA before Template:IPA, which is compressed rather than rounded Template:IPA. It is most commonly romanized as fu (as in Fuji), but hu is often used when the underlying morphology is more important than pronunciation (see kunrei-shiki).
