Fault-tolerant systems and methods to process and correct input spelling errors for non-Roman based languages such as Chinese, Japanese, and Korean (CJK) are disclosed. The method may be applied to a Chinese input method using pinyin. For example, the method may generally include receiving a pinyin input representing characters in Chinese, the input having at least one original pinyin, identifying potentially incorrect pinyins in the input, expanding each potentially incorrect pinyin to at least one additional alternative pinyin, each pair of potentially incorrect and corresponding alternative pinyin having a proximity measurement, converting each pinyin in the input and each alternative pinyin to Chinese characters, computing likelihoods of possible conversions of the pinyin input to Chinese characters, each possible Chinese conversion being a combination of the converted original and/or alternative pinyins of the input, the probabilities being based on the proximity measurement and optionally on a context of the possible Chinese conversion, and determining a most likely Chinese conversion from the possible conversions.
