The spelling of the word "Toshia" is quite straightforward once you understand the International Phonetic Alphabet (IPA) transcription of the word. The IPA phonetic transcription of "Toshia" is /'tɑʃə/. The first sound is a voiceless alveolar fricative (/ʃ/), followed by an unstressed schwa sound (/ə/), and ending with an "a" sound pronounced like "ah" (/ɑ/). So when you hear "Toshia," remember to spell it with an "I" in the middle, not an "o" like "Toshoa" or "Toshio."
