In the Beginning Quotes

“English speakers will readily agree that dogs and cats do not end with the same sound once that fact is pointed out, but most will not realize it for themselves. Likewise, in Spanish, too, the pronunciation of the letter s differs from word to word. And in Russian, the pronunciation of the letter g (Γ) differs from word to word (though, admittedly, the Russian g is somewhat anomalous, in that most Russian letters show less variation from word to word); the pronunciation of the vowels also varies considerably from word to word. The imperfect match between sounds and letters in these languages reflects the fact that even native speakers often do not understand the sounds of their langauge.”
― Joel M. Hoffman, In the Beginning: A Short History of the Hebrew Language
