METHOD AND SYSTEM FOR AUTOMATIC SPEECH RECOGNITION

摘要

A method of recognizing speech is provided that includes generating a decoding network that includes a primary sub-network and a classification sub-network. The primary sub-network includes a classification node corresponding to the classification sub-network. The classification sub-network corresponds to a group of uncommon words. A speech input is received and decoded by instantiating a token in the primary sub-network and passing the token through the primary network. When the token reaches the classification node, the method includes transferring the token to the classification sub-network and passing the token through the classification sub-network. When the token reaches an accept node of the classification sub-network, the method includes returning a result of the token passing through the classification sub-network to the primary sub-network. The result includes one or more words in the group of uncommon words. A string corresponding to the speech input is output that includes the one or more words.

1. A method of recognizing speech, comprising:
generating a decoding network for decoding speech input, the decoding network comprising a primary sub-network and one or more classification sub-networks, wherein:
the primary sub-network includes a plurality of classification nodes, each classification node corresponding to a respective classification sub-network of the one or more classification sub-networks; andeach classification sub-network of the one or more classification sub-networks corresponds to a group of uncommon words; receiving a speech input; and decoding the speech input by:
instantiating a token corresponding to the speech input in the primary sub-network;passing the token through the primary network;when the token reaches a respective classification node of the plurality of classification nodes, transferring the token to the corresponding classification sub-network;passing the token through the corresponding classification sub-network;when the token reaches an accept node of the classification sub-network, returning a result of the token passing through the classification sub-network to the primary sub-network, wherein the result includes one or more words in the group of uncommon words corresponding to the classification sub-network outputting a string corresponding to the speech input that includes the one or more words.
