Basic consonants in English display some articulatory processes...This mind map provides you with the most concise information about some of them. Please, take a look!!!
These consonant sounds are called stops because the air
is stopped when it gets to the oral cavity (the place
where consonants are mostly produced).
Basic Articulatory Processes of Stops
Aspiration
This only happens in the
voiceless stops sounds
[p], [t], [k] when they
are in initial position)
Neutralization
When the voiced stops
[b], [d], and [g] are
pronounced in final
position by Spanish
speakers, they
mispronounced them. As a
result, there occurs
“Neutralization”.
Flapping
When the spellings [t], [d], [rt]
and [tl] are between vowels and
the first syllable is stressed, they
are regularly flapped sounds.
Nasal Sounds
These consonant sounds are called nasals because the air escapes through
the nose. In other words, the air is blocked and diverted through the nose.
Basic Articulatory Processes of Nasals
Nasalization
When a vowel is preceded by a
nasal sound (vowel before a
nasal sound which is in middle
position), there happens
nasalization. It only occurs in
English and it is predictable.
*Syllabic [ņ] and Sylllable Dropping
When an unstressed syllable begins with
[t] or [d] and ends with [n], the [n]
is frequently pronounced as syllabic
[ņ]. In order to do so, you should keep
the tongue tip on the upper gum ridge
without moving it from the position of
the preceding [t] or [d].
