English pronunciation (see English Pronunciation) is shaped by its stress-timed rhythm and a legacy of historical sound shifts — both are practicable with the right specific exercises.
Say a sentence while tapping only on the stressed syllables, letting unstressed syllables compress to fit between taps — this physically demonstrates English's stress-timed rhythm in a way that's hard to grasp just by reading about it.
Track words with silent letters you encounter ("knight," "island," "debt") in a running list, since there's no reliable rule to derive them from — direct memorization of specific words is more efficient than searching for a pattern that doesn't fully exist.
English vowel sounds that don't exist in your native language (if any) benefit from minimal-pair practice, the same technique useful in Arabic or French — find pairs that differ by exactly one vowel sound and drill them back-to-back.
Repeating natural audio immediately after hearing it (shadowing) builds the reduced forms and linking patterns of connected speech directly into your own pronunciation, rather than only recognizing them passively.

Stressed syllables occur at roughly even intervals, with unstressed syllables compressed to fit between them — practicing a sentence while tapping only on stressed syllables physically demonstrates this rhythm.
Not really — building a personal running list of specific words with silent letters and memorizing them directly is more efficient than searching for a consistent rule.
Minimal-pair practice — finding word pairs that differ by exactly one vowel sound and drilling them back-to-back — the same technique useful for hard sounds in other languages.
Repeating natural audio immediately after hearing it — it builds connected-speech habits (reduced forms, linking) directly into your own pronunciation rather than just recognizing them passively.
