Abstract

The invention provides a distributed voice processing system and method. The system comprises a plurality of node devices in a network, wherein each node device comprises a processor, a memory, a communication module and a sound processing module, and at least one node device comprises a sound acquisition module; the sound acquisition module is configured to acquire an audio signal; the sound processing module is configured to pre-process the audio signal to obtain a first sound pre-processing result; the communication module is configured to send the first sound preprocessing result to one or more node devices in the network; the communication module is further configured to receive one or more second sound preprocessing results from at least one other node device from the network; and the sound processing module is further configured to perform voice recognition based on the first sound preprocessing result and / or the one or more second sound preprocessing results. According to the invention, a decentralized design is realized, and the efficiency, stability and robustness of voice recognition are improved.

Description

technical field [0001] The present application relates to the field of distributed speech processing, in particular to a distributed speech processing system and method. Background technique [0002] Speech recognition technology and keyword recognition technology are becoming more and more mature, and are more and more widely used in the market. For example, children's toys, educational products, smart home and other products have added speech recognition function to realize the function of voice interactive control. [0003] There are currently two common methods for speech recognition, one is local recognition based on a single device, and the other is based on local recognition combined with server cloud recognition. [0004] For the first method, a single device commonly used in the smart home market realizes local voice control. The voice recognition process is to collect the original voice into a device, and perform calculations on this device to obtain the recognitio...
