The invention relates to a multimedia-based, multi-platform, multi-terminal, and multi-language translation method with high translation accuracy. The invention includes the following steps: (1) information classification and recording; (2) client terminals, after system initialization, can be used to select the language environment suitable for themselves. The language, called Language A, can be clicked to enter the interface; (3) the client terminals select the target language B in the suitable language environment; (4) information searching; (5) the client terminals can continue to select the target language C according to the multimedia information. The server terminals, according to the multimedia information, search the corresponding pronunciation and paraphrase of language C in the multi-language meaning database, and send the result to the client terminal through analysis program, thus completing the multi-language translation from Language A to Language B, and then to Language C based on multimedia. The invention can, with multimedia information as the medium for the multilingual translation, directly reveal the meaning of sentences to achieve the translation accuracy of information interactivity among multiple languages.
