Abstract: A method of phonetic spelling check is disclosed. The method includes providing a phonetic mapping representing the relationship between letters and corresponding phonetic symbols, wherein each of the letters maps to at least one of the phonetic symbols, and the phonetic mapping is established in accordance with rules of English pronunciation. The letters may include English letters, phonetic alphabets and wild cards. Next, generate phonetic string including the phonetic symbols according to replaceability of the phonetic symbols by separately processing the English letters, phonetic alphabets and wild cards. Finally, filter out a portion of the phonetic strings according to some spelling rules of English language.
