Pronouncing the silent T after N.
In "into", the "t" right after N is dropped — the tongue skips the T stop and moves directly from the N position to the next sound. /t/ is completely silent — the tongue skips the T stop and moves directly from the N position to the next sound.
Treating every L the same.
The L in "cells" 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.
Inserting a vowel before the syllabic consonant.
In "potential", 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.
Pausing between the words.
The "" at the end of "" flows directly into the vowel starting "" — the consonant migrates to the next word with no pause between. Final consonant "migrates" to next word — no pause between.
