6. An electronic device comprising: a memory storing instructions; and a processor executing the instructions to: detect one or more character inputs in a first character alphabet as a preceding character string, the preceding character string corresponding to one or more valid characters in a second alphabet according to a transliteration operation; detect a current character input in the first character alphabet following input of the preceding character string; determine whether the current character input is an ambiguous input; and selectively suspend processing of the current character input by the transliteration operation.

The electronic device of claim 6 , the processor executing instructions to continue processing of the current character input upon occurrence of a finalization event, wherein the finalization event includes at least one of a detection of another input by a different input key within a predetermined period of time after the current input, and an expiration of the predetermined period of time after the current input without detecting another input.
