The spelling of the word "shiraki" is based on its pronunciation, which can be explained through the use of IPA phonetic transcription. While the initial "sh" sound is fairly straightforward, the "i" sound is represented using the symbol /ɪ/, which indicates a short "ih" sound. The "r" sound is a bit different in Armenian spelling, where the "r" is pronounced rolled. Finally, the "-aki" ending uses the letters "a" and "ki" to represent a more complex sound which sounds similar to "-uh-kee". By knowing these sounds and symbols, the correct spelling of "shiraki" becomes clear.
