bilabial

E.g., P and B differentiating sounds are both bilabial plosives, differing only in whether they are voiced.

For demonstrating lack of assimilation of /n/ to following bilabial, there are a couple distinct questions you might ask.

Why do people in the north drop word final schwa but in the south they add a nasal bilabial?

The words for father/mother are often a bilabial and open syllable combination regardless of language family origin.

How am I supposed to designate voiced bilabial fricatives and ask for Bitcoin donations on the same page?

But also, the page you've linked to is misleading - it says that Spanish B/V is [b] (bilabial plosive), while in practice it's [β] (bilabial fricative or approximant) in most positions, with [b] as allophone.

Both the negative prefix `mh` and 5 are bilabial nasal, not velar nasal.

Consider where you pronounce 'm' and 'p': they're both bilabial consonants.

Those of us with dirty minds favor the bilabial fricative.

It's very frequent for people to preserve the tongue gesture associated with /n/, because a bilabial stop doesn't use the tongue and so [n] is easily coarticulated.

Both B and M are voiced bilabial consonants.

Sure, now show us lack of assimilation to a subsequent bilabial (in a context where /nk/ does assimilate), which is what Japanese does and that you're implying English does differently (it doesn't).

For what is worth, the voiced bilabial fricative is a sound similar to English "b" and "v".

While I imagine the lip smack is the bilabial click, ʘ, he clearly distinguishes between the two, so I wonder what's with using "x" for both.

Another related example as a foreign speaker before articulating "psychology" I will form the unvoiced bilabial plosive "p" with my lips before executing "saɪˈkɑlədʒɪ".

Words spelled "mp" are reliably [mp] in the modern language, but it's not a simple case as "mp" spelling /mp/ read [mp] and "np" spelling /np/ read [np]; English phonotactics also coerces the nasal in /np/ to a bilabial realization.

English has an almost full series of stop and fricative phonemes that exhibit voicing contrasts: - Bilabial, alveolar, and velar stops /p, b, t, d, k, g/, though the distinction between /t/ and /d/ disappears intervocalically in American English.
