Abstract

The invention provides a distributed voice processing system and method. The system comprises a plurality of node devices forming a network, wherein at least one node device comprises a sound acquisition module; a sound acquisition module configured to acquire an audio signal; a sound processing module configured to pre-process the audio signal to obtain a first sound pre-processing result; a communication module further configured to receive one or more second sound pre-processing results from at least one other node device from the network; wherein the sound preprocessing result comprises a data block and each data block comprises time information and an incremental sequence number; and a sound processing module further configured to splice data blocks of the first sound preprocessing result and / or the one or more second sound preprocessing results according to an increasing sequence of the increasing sequence numbers so as to obtain a complete third sound preprocessing result, and process the third sound preprocessing result so as to obtain a final voice recognition result. According to the invention, the decentration design is realized, and the speech recognition efficiency, stability and robustness 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...
