    Abstract: Disclosed are a method, an apparatus, a computer device and a storage medium for decoding speech data. The method comprises acquiring at least one transcribed text obtained by transcribing the speech data; acquiring score of each transcribed text; acquiring at least one preset hot word corresponding to the speech data, each preset hot word corresponds to a reward value; and calculating, when there is a string matched with the preset hot word in the transcribed text, a target score of the transcribed text according to the reward value of the matched string and the score of the transcribed text, where the target score is used to determine the decoded text of the speech data. Hot word matching is performed on the transcribed text. If there is a matching hot word, the score of the transcribed text will be increased. The accuracy of decoding is improved without updating the model, and the operation is simple.

    Abstract: The present application provides a robot response method, apparatus, device and storage medium. The method includes: obtaining, by a robot, current query voice; extracting semantic information of the current query voice; matching the semantic information of the current query voice with multiple semantic information clusters stored in advance to get a matched target semantic information cluster, where each semantic information cluster includes: at least one Q&A instance, and each Q&A instance includes: semantic information corresponding to a historical query voice and a query question selected in a query list corresponding to the historical query voice; and obtaining, by the robot, the number of times each query question was selected in the target semantic information cluster, determining, according to the number of times each query question was selected, a target query question corresponding to the current query voice, and outputting a query response corresponding to the target query question.

    Abstract: The invention, which discloses a blockchain consensus method, apparatus and system, relates to the technical field of computers. A specific implementation mode of the method comprises: a leader node in the same network as a client receiving a transaction message sent by the client and a transaction message sent by at least one peer node, or receiving transaction messages sent by at least two peer nodes; sending the transaction messages to a leader node in a previous-level network till the priority of the previous-level network is the highest if transaction data in the transaction messages are consistent; a leader node in a highest-priority network generating a proposal message according to the received transaction messages, and performing a consensus judgment on the proposal message based on a Byzantine fault-tolerant consensus mechanism; sending the proposal message to a leader node in a next-level network till the next-level network is the network where the client is located after the success in the consensus judgment. The implementation mode can solve the technical problems of a long transaction confirmation time and a small transaction volume carried by a block.

    Abstract: A method for recognizing speech comprises: respectively setting initial values of a Chinese character coefficient and a Pinyin coefficient, generating a Chinese character mapping function according to the initial value of the Chinese character coefficient, and generating a Pinyin mapping function according to the initial value of the Pinyin coefficient (S101); training the Chinese character mapping function and the Pinyin mapping function using a plurality of preset training samples, calculating training results as parameters of a joint loss function, and generating a target mapping function according to calculation results (S102); and recognizing, according to the target mapping function, speech to be recognized, so as to obtain a Chinese character recognition result and a Pinyin recognition result of the speech to be recognized (S103). The method reduces the cost of speech recognition while ensuring the accuracy of speech recognition.
