PURPOSE: The method for interpreting morpheme used in a document interpreter of a voice synthesizer and an apparatus thereof are provided to enhance naturalness and clearness of a voice synthesizer by deciding kind of a sentence and kind of each paragraph composing a sentence, thereby creating a pronunciation suited thereto. CONSTITUTION: A document preprocessor comprises a sentence extracting unit(20), a user preapplying unit(24) and special pattern processor(26). The sentence extracting unit(20) receives a document and extracts the document as a token list type. The user preapplying unit(24) replaces a word row by a replacement word row corresponding to the word row if the word row stored in user dictionary database(22) is included in the token list typed document. The special pattern processor(26) decides a kind of extracted sentence and decides a kind of pattern by extracting a special pattern, and modifies a position of space. The token list typed document extracted from the document preprocessor is transmitted to a morpheme interpretation unit. The morpheme interpretation unit comprises a morpheme combination creating unit, a reserve list creating unit, a morpheme interpretation list creating unit and a morpheme error modifying unit. The morpheme combination creating unit receives the token list typed document from the document preprocessor and creates all sorts of combinations of morphemes. The morpheme interpretation list creating unit selects a reserve morpheme list having a value multiplying a connection weight value of a morpheme and a word as the last morpheme interpretation list.
