obtaining an audio encoding result, wherein the audio encoding result comprises a plurality of elements, and each element in the audio encoding result comprises a coordinate in an audio frame number dimension and a coordinate in a text label sequence dimension;

in response to that an output result of an i^th frame in a decoding path is a non-null character, respectively increasing the coordinate in the audio frame number dimension and the coordinate in the text label sequence dimension corresponding to an output position of the i^th frame by 1 to obtain an output position of a (i+1)^th frame in the decoding path, wherein i is an integer greater than or equal to 1; and

determining an output result corresponding to the output position of the (i+1)^th frame in the decoding path according to the output result of the i^th frame in the decoding path and an element of the (i+1)^th frame in the audio encoding result.
