Problems solved by technology

[0003] However, the current wake-up schemes are all judged at the voice frame level. For example, the input voice has 100 frames, and the actual text is very little. Through the above-mentioned wake-up scheme, the decoding path with a length of 100 will be searched to determine whether to recall , resulting in slower decoding

Abstract

The embodiment of the invention discloses a voice wake-up method, device and equipment. The method comprises the steps of for an acquired to-be-processed voice signal, acquiring to-be-processed voice features from the to-be-processed voice signal, and coding the to-be-processed voice features to obtain acoustic coding representations; after the acoustic coding representations corresponding to the to-be-processed voice signal are obtained, carrying out integration according to the acoustic coding representations and the weights corresponding to the acoustic coding representations, and then obtaining a character sequence included in the to-be-processed voice signal according to the integrated acoustic coding representations; and after the character sequence is obtained, determining whether to wake up the equipment or not according to the character sequence and the keyword. That is, possible characters are acquired from the to-be-processed voice signal, and then whether to wake up or not is judged based on the character level instead of a voice frame, so that the wake-up efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of computer processing, and in particular to a voice wake-up method, device and equipment. Background technique [0002] Voice wake-up is a very important technology in the voice field at present, and it is more deployed on hardware, which helps users complete some tasks after receiving voice commands. Traditional wake-up methods usually include an acoustic model for speech recognition and finite state transducers (Finite State Transducers, FST) including keywords and path clipping, and judge whether to wake up based on confidence. [0003] However, the current wake-up schemes are all judged at the voice frame level. For example, the input voice has 100 frames, and the actual text is very little. Through the above-mentioned wake-up scheme, the decoding path with a length of 100 will be searched to determine whether to recall , resulting in slower decoding. Contents of the invention [0004] In ...
