Transliteration, which adapts written form altering the pronunciation when spoken out, is opposed to letter transcription, which is a letter by letter conversion of one language into another writing system. Still, most systems of transliteration map the letters of the source script to letters pronounced similarly in the target script, for some specific pair of source and target language. Transliteration may be very close to letter-by-letter transcription if the relations between letters and sounds are similar in both languages.
