Common pronunciation mistakes in American English.
The textbook way isn't wrong — it's just not how anyone actually says it.
Pronouncing the vowel before M/N too pure.
In "and", the "a" vowel before M or N raises and fronts toward [eə] — the tongue pulls up and forward, breaking the vowel into a tense glide as it anticipates the nasal. The "/æ/" vowel raises and fronts before M or N — tongue pulls up and forward, producing a tense [eə] glide (between /e/ and /ə/). Not a pure /æ/.
Treating every L the same.
The L in "signaled" is a dark L — the back of the tongue rises toward the soft palate, adding a small "uh" quality before the L. Dark L adds a small schwa-like "uh" before the L. The back of the tongue lifts toward the soft palate.
Releasing the final consonant with a puff of air.
In "signaled", the "" is not released — the articulators get into position but hold without the burst of air. Air stops but there's no release burst — the articulators hold position.
Inserting a vowel before the syllabic consonant.
In "siren", the short unstressed vowel before "" disappears — the schwa is absorbed and the "" becomes the syllable nucleus on its own. Schwa is absorbed — consonant becomes the syllable nucleus.
