words pronounced with their letters reversed

Bible is not pronounced with “reversed letters”: the e is silent. Words like rhythm, acre, centre, bible, bottle, little, button all simply have syllabic consonants. For example:

• bible [ˈbaɪbɫ̩]
• little [ˈlɪtɫ̩]
• Favre [ˈfɑvɹ̩]
• acre [ˈeɪkɹ̩]
• centre [sɛntɹ̩]
• button [ˈbʌtn̩]
• even [ˈiːvn̩]
• awful [ˈɔːfɫ̩]
• rhythm [ˈɹɪðm̩]

Those all have two syllables, and all without a vowel in the second syllable. The consonants are acting as the syllabic center, which makes them fundamentally vowel-behaving, normally called syllabic consonants.

If you are talking about why some people will ^{_{(“mis‑”)}}pronounce words like cavalry as calvary, or for that matter croqueta as corqueta, please see metathesis.
