In casual American English, "I have to get back to my desk now" sounds like "ahy hav tuh GEHT BAK tuh mahy DEHSK NOW". Three things happen here, and the headline one is the Unreleased Stops: the final stop consonant closes without a puff of air. Keep stressed words long, unstressed words short, and link the consonants forward into the vowels.

In "get", the "" is not released — the articulators get into position but hold without the burst of air. This is called the Unreleased Stops, and it's why Americans sound more relaxed than the textbook. It comes out as GEHT.

Small tricks that turn a textbook sentence into how an American actually says it.
Common pronunciation mistakes in American English.
The textbook way isn't wrong — it's just not how anyone actually says it.
Releasing the final consonant with a puff of air.
In "get", 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.
Pronouncing the function word too fully.
"have" is a function word — in connected speech, the full vowel reduces to a quick "" sound and consonants may simplify. Full vowel reduces to schwa /ə/ or other weak vowel. Consonants may simplify.
Pronouncing the H clearly.
The "h" in "have" is dropped in connected speech — the preceding word's final consonant links directly to the remaining vowel — most natural in casual, rapid speech; in careful or formal speech, the H is typically kept. /h/ is dropped entirely — preceding word links directly into the remaining vowel (works after both consonants and vowels).
