Claim 3:
4. The method according to claim 1, wherein the decoding the current audio frame according to the first token list, the pruning parameters, and the acoustic vector comprises:
inputting the acoustic vector into the first decoding network, and traversing each first token in the first token list;
for any first token, determining whether to skip the first token according to a decoding score corresponding to the first token and the first pruning parameter;
when it is determined to execute the first token according to the first pruning parameter, traversing non-empty input edges in the first decoding network by using the first state of the first token as a start state, and determining whether to skip the first token according to the second pruning parameter and a second decoding path formed by each non-empty input edge;
when it is determined to execute the first token according to the second pruning parameter, rescoring the second decoding path formed by the non-empty input edge in the second decoding network by using the second state of the first token as a start state, and determining whether to skip the first token according to a rescoring result and the third pruning parameter;
when it is determined to execute the first token according to the third pruning parameter, obtaining a second token by performing a state jump on the first token, the second token comprising an updated state pair and a decoding score;
combining second tokens corresponding to all the first tokens into a second token list; and
determining a second token with a smallest decoding score in the second token list as a decoding result of the current audio frame.
