Voiceless bilabial plosive

The voiceless bilabial plosive or stop is a type of consonantal sound used in most spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨p⟩, and the equivalent X-SAMPA symbol is p.

Features

Features of the voiceless bilabial plosive:

• Its manner of articulation is occlusive, which means it is produced by obstructing airflow in the vocal tract. Since the consonant is also oral, with no nasal outlet, the airflow is blocked entirely, and the consonant is a plosive.
• Its place of articulation is bilabial, which means it is articulated with both lips.
• Its phonation is voiceless, which means it is produced without vibrations of the vocal cords. In some languages the vocal cords are actively separated, so it is always voiceless; in others the cords are lax, so that it may take on the voicing of adjacent sounds.
• It is an oral consonant, which means air is allowed to escape through the mouth only.
• Because the sound is not produced with airflow over the tongue, the central–lateral dichotomy does not apply.
• Its airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the intercostal muscles and abdominal muscles, as in most sounds.

Occurrence

Research has shown that incidental learning positively impacts the acquisition of the /p/ sound for Arabic speakers and other EFL learners.^[1][2] This is particularly interesting given that the stop /p/ is missing from about 10% of languages that have a /b/. (See voiced velar stop for another such gap.) This is an areal feature of the circum-Saharan zone (Africa north of the equator plus the Arabian Peninsula). It is not known how old this areal feature is, and whether it might be a recent phenomenon due to Arabic as a prestige language (Arabic shifted /p/ to /f/ but the timing of this change is not known), or whether Arabic was itself affected by a more ancient areal pattern.^[2] It is found in other areas as well; for example, Fijian, Onge, and many Papuan languages have /b/ but no /p/.

Nonetheless, the /p/ sound is very common cross-linguistically. Most languages have at least a plain /p/, and some distinguish more than one variety. Many Indo-Aryan languages, such as Hindustani, have a two-way contrast between the aspirated /pʰ/ and the plain /p/ (also transcribed as [p˭] in extensions to the IPA).
