In casual American English, "I can't go with you, therefore I'll stay here" sounds like "ahy KANT GOH wihth yoo DHAIR-for ahyl STAY HEER". Several things happen here, and the headline one is the Consonant-to-Vowel Linking: the consonant links forward into the next vowel without a pause. Keep stressed words long, unstressed words short, and link the consonants forward into the vowels.

What makes this sentence sound American.
The "" at the end of "therefore" flows directly into the vowel starting "i'll" — the consonant migrates to the next word with no pause between. This is called the Consonant-to-Vowel Linking, how Americans glue words together so they sound like one phrase. It comes out as DHAIR-for.

The textbook way isn't wrong — it's just not how anyone actually says it.
Pronouncing the vowel before M/N too pure.
In "can't", 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 "i'll" 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.
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.
Pronouncing every consonant in the cluster.
The "" at the end of "" is dropped before the consonant starting "" — the surrounding consonants flow directly together — common in flowing natural speech; in careful or formal speech, the sound is often kept. The /t/ or /d/ at the end is dropped — surrounding consonants flow directly.
