A voiceless labial-velar fricative, or more accurately a voiceless labialized velar fricative and sometimes analyzed as a voiceless labial-velar approximant, is a type of consonantal sound, used in spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨xʷ⟩ or, rather ambiguously, ⟨ʍ⟩. The letter ⟨ʍ⟩ was defined as a "voiceless [w]" until 1979, when it was defined as a fricative with the place of articulation of [k͡p] the same way that [w] is an approximant with the place of articulation of [ɡ͡b]. The IPA Handbook describes ⟨ʍ⟩ as a "fricative" in the introduction, while a chapter within characterizes it as an "approximant".
There has historically been some controversy over whether a voiceless approximant could be distinct from a fricative, but more recent research distinguishes between turbulent (fricative-like) and laminar (vowel- or approximant-like) airflow in the vocal tract. English /ʍ/ is an approximant [w̥], a labialized glottal fricative [hʷ], or a [hw] sequence, not a velar fricative. Scots /ʍ/ has been described as a velar fricative, especially in older Scots and peripheral dialects, where it is [xw]. Ladefoged and Maddieson were unable to confirm that any language has fricatives produced at two places of articulation, as the term "labial-velar" implies. They conclude that "if [ʍ] is a fricative, it is better described as a voiceless labialized velar fricative".
01Features
Features of a voiceless labialized velar 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 labialized velar, which means it is articulated with the back part of the tongue raised toward the soft palate (the velum) while rounding the lips.
- Its phonation is voiceless, which means it is produced without vibrations of the vocal cords.
- It is an oral consonant, which means that air is not allowed to escape through the nose.
- It is a median consonant, which means it is produced by directing the airstream down the midline of the tongue, rather than to the sides.
- Its airstream mechanism is pulmonic, which means it is articulated by pushing air only with the intercostal muscles and abdominal muscles, as in most speech sounds.

| English | Received Pronunciation in some Irish and Scottish speakers | whine | [w̥aɪ̯n] | 'whine' | English /ʍ/ is generally a labialized velar approximant. It is usually represented phonemically as /hw/, but phonetically it is not a sequence of [h] plus [w] (see English phonology). In General American and New Zealand English only some speakers maintain a distinction with /w/; in Europe, mostly heard in Irish and Scottish accents.
