摘要： A corresponding grammar description file and a word category description file are defined based on a logical grammar by manifest language LGML according to a common sentence expression of a semantic meaning, in the grammar description file, the description for a common sentence is composed by operators, word categories, and functions, the word category description file is used to describe specific values for the word categories; the grammar description file and the word category description file are generated, with a reduction method according to a defined sequence, into a grammar tree for the grammar description file and word category trees for the word category description file; the word category trees are grafted at the positions of corresponding word categories on the grammar tree, forming a grammar tree for the semantic meaning, in this way, grammar compiling is accomplished. Based on the grammar tree of a semantic meaning with aforementioned ways, semantic parsing is carried out with whole-sentence matching, semantic mapping matching, or a combination of whole-sentence matching and semantic mapping matching.

摘要： A method, apparatus, device, and computer readable storage medium for recognizing and decoding a voice based on a streaming attention model are provided. The method may include generating a plurality of acoustic paths for decoding the voice using the streaming attention model, and then merging acoustic paths with identical last syllables of the plurality of acoustic paths to obtain a plurality of merged acoustic paths. The method may further include selecting a preset number of acoustic paths from the plurality of merged acoustic paths as retained candidate acoustic paths. Embodiments of the present disclosure present a concept that acoustic score calculating of a current voice fragment is only affected by its last voice fragment and has nothing to do with earlier voice history, and merge acoustic paths with the identical last syllables of the plurality of candidate acoustic paths.
