In fact, the labial is the least stable of the voiceless plosives in the languages of the world, as the unconditioned sound change [p] → [f] (→ [h] → Ø) is quite common in unrelated languages, having occurred in the history of Classical Japanese, Classical Arabic, and Proto-Celtic, for instance.
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.
Voice or voicing is a term used in phonetics and phonology to characterize speech sounds (usually consonants). Speech sounds can be described as either voiceless (otherwise known as unvoiced) or voiced. The term, however, is used to refer to two separate concepts:

Lendu has been claimed to have voiceless /ƥ ƭ ƈ/, but they may actually be creaky-voiced implosives. [9] The voiceless labial–velar implosive [ƙ͜ƥ] also may occur in Central Igbo. [19] [20] Some English speakers use a voiceless velar implosive [ƙ] to imitate the "glug-glug" sound of liquid being poured from a bottle, but others use a ...
If the consonant is voiced, the voicing is the only sound made during occlusion; if it is voiceless, a stop is completely silent. What we hear as a /p/ or /k/ is the effect that the onset of the occlusion has on the preceding vowel, as well as the release burst and its effect on the following vowel.
In phonetics, voice onset time (VOT) is a feature of the production of stop consonants.It is defined as the length of time that passes between the release of a stop consonant and the onset of voicing, the vibration of the vocal folds, or, according to other authors, periodicity.
Taa distinguishes the singular and plural of many nouns via a voiceless vs. voiced initial consonant, and thus there are voiced and voiceless versions of the glottalized nasal and oral clicks. In the voiced versions the glottalization is delayed, so that the hold of the click is partially voiced or nasalized: that is, [ǃˀa] vs. [ᶢǃʔa] and ...
