Kind Code:
A1
Abstract:
A speech recognition method and apparatus, and a device and a medium. The method comprises: using an acoustic model to process speech data to be recognized and a first text segment that has been recognized, so as to obtain respective acoustic probabilities of a plurality of alternative text segments (S210); using a first language sub-model to process the first text segment, so as to obtain respective initial language probabilities of the plurality of alternative text segments (S220); using a constraint sub-model to process the first text segment, so as to obtain respective extensible relationships of the plurality of alternative text segments with respect to the first text segment (S230); adjusting the initial language probabilities of the alternative text segments according to the extensible relationships, so as to obtain respective first language probabilities of the plurality of alternative text segments (S240); and determining a target text segment from among the plurality of alternative text segments according to the first language probabilities and the acoustic probabilities (S250).
