A system and method for semantic analysis of speech, the semantic speech analysis system being used for implementing semantic analysis of speech in a preset field, comprising: a storage unit (1), used for storing semantic sentences in the preset field, each semantic sentence corresponding to an address, the semantic sentences comprising characters and keywords, each keyword corresponding to a tag, and a word list being prearranged in the storage unit (1), used for storing the address of the semantic sentence in which each word appears and/or the address of the semantic sentence in which each tag appears; an acquisition unit (2), used for acquiring speech sentences to be analysed; an indexing unit (3), being respectively connected to the storage unit (1) and the acquisition unit (2), and being used for searching the semantic sentences in the storage unit (1) on the basis of the speech sentences to be analysed, acquiring candidate semantic sentences matching the speech sentences to be analysed and a corresponding candidate order; and an analysis unit (4), connected to the indexing unit (3), and being used for using a fuzzy match algorithm, on the basis of the sorted candidate sentences, to analyse the speech sentences to be analysed, and acquiring analysis results.
