The textbook way isn't wrong — it's just not how anyone actually says it.
Saying a hard "T" in the middle.
In "letter", the "t" between vowels sounds like a quick "d" — the tongue briefly taps the ridge behind the upper teeth. /t/ or /d/ becomes a quick tap [ɾ] — sounds like a soft D. The tongue briefly taps the ridge behind the upper teeth.
Hard T at the end of a word, not a flap.
The "t" at the end of "" links to the vowel starting "" — it flaps to sound like a quick "d", with the tongue briefly tapping the ridge behind the upper teeth. Same flap as within-word (R1) but spanning two words.
Pronouncing the function word too fully.
"a" 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 "her" 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).
