11. An electronic device comprising: a storage unit, storing a basic corpus and a temporary corpus, the basic corpus recording a vast amount of vocabularies, words and phrases and the frequency of use of each word and each phrase, the temporary corpus recording the mapping relationship between at least one substitute vocabulary and at least one temporary meaning; an input unit, configured for generating signals in response to a user's input; a voice and character converting module, configured for converting the signals into a textualized message in a predetermined language; a language analysis module, configure for segmenting the textualized message into at least one vocabulary, obtaining at least one vocabularized segment comprising the at least one vocabulary, segmenting the textualized message based on the vocabularized segments and a sentence construction rule, obtaining at least one sentence segment, retrieving the frequency of use of each segmented vocabulary from the basic corpus, obtaining a first language understanding result of the textualized message by analyzing the at least one vocabularized segments and the at least one sentence segments, based on the retrieved frequency of use of each segmented vocabulary; a determination module, configured for selecting a plurality of textualized messages consecutively converted within a predetermined time period, the selected textualized messages including said textualized message segmented by the language analysis module and analyzing the selected textualized messages, using a contextual understanding method, so as to determine whether the first language understanding result is a reasonable understanding, determining at least one substitute vocabulary causing the unreasonable understanding, and determining whether the temporary corpus records the determined at least one substitute vocabulary; and an intelligent conversation module, configured for determining a reply message based on a reasonable language understanding result, the temporary corpus, and the basic corpus; wherein the language analysis module is further configured for determining temporary meaning of each determined substitute vocabulary not recorded in the temporary corpus by analyzing the context comprising the determined substitute vocabulary to obtain a second understanding result of the textualized message, and updating the temporary corpus by storing the mapping relationship between the determined at least one substitute vocabulary and the temporary meaning therein.
