A 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 ⟨ɸ⟩, a Latinised form of the Greek letter Phi.

👉 Voiceless bilabial fricative in the context of Labial consonant
Labial consonants are consonants in which one or both lips are the active articulator. The two common labial articulations are bilabials, articulated using both lips, and labiodentals, articulated with the lower lip against the upper teeth, both of which are present in English. A third labial articulation is dentolabials, articulated with the upper lip against the lower teeth (the reverse of labiodental), normally only found in pathological speech. Generally precluded are linguolabials, in which the tip of the tongue contacts the posterior side of the upper lip, making them coronals, though sometimes, they behave as labial consonants.
The most common distribution between bilabials and labiodentals is the English one, in which the nasal and the stops, [m], [p], and [b], are bilabial and the fricatives, [f], and [v], are labiodental. The voiceless bilabial fricative, voiced bilabial fricative, and the bilabial approximant do not exist as the primary realizations of any sounds in English, but they occur in many languages. For example, the Spanish consonant written b or v is pronounced, between vowels, as a voiced bilabial approximant.

Voiceless bilabial fricative in the context of Phi
Phi (/ˈfaɪ, ˈfiː/ FY, FEE; uppercase Φ, lowercase φ or ϕ; Ancient Greek: ϕεῖ pheî [pʰéî̯]; Modern Greek: φι fi [fi]) is the twenty-first letter of the Greek alphabet.
In Archaic and Classical Greek (c. 9th to 4th century BC), it represented an aspirated voiceless bilabial plosive ([pʰ]), which was the origin of its usual romanization as ⟨ph⟩. During the later part of Classical Antiquity, in Koine Greek (c. 4th century BC to 4th century AD), its pronunciation shifted to a voiceless bilabial fricative ([ɸ]), and by the Byzantine Greek period (c. 4th century AD to 15th century AD) it developed its modern pronunciation as a voiceless labiodental fricative ([f]).The romanization of the Modern Greek phoneme is therefore usually ⟨f⟩.
