Are words always pronounced as spelled?


I came across the word ケーブルカー, or cable-car.

Based on the pronunciation I have, the ブ and ル are pronounced like one
syllable (like 'brr') instead of two like I expected ('bu ru').

Is this an exception or is the second pronunciation correct (or am I wrong all
together)?




It can't be said clearly which. It doesn't have 2 syllables like it has in
English, but also doesn't ignore both of 2 "u"s.

I think close one for ケーブルカー is [ke-burka-]. Even though, this "r" should be
pronounced with "u" mouth. So even a vowel is actually silent, you need to
shape your mouth for that vowel like whispering. (of course sounding it is
also okay)  
  

Examples

規定 [kite-](rule): first "i" isn't a syllable but mouth has to be shaped い.  
心 [kokoro](heart): first "o" isn't a syllable but mouth has to be shaped お.  
  

In phrases

よろしくお願いします： first し and last す doesn't have vowel sound  
はじめまして: last し doesn't have vowel sound
