Problems solved by technology

[0004] However, for different acoustic scenarios, such as the size of the noise in the environment, whether the speaker is in the playing state, and the presence of echoes, the existing voice wake-up model is difficult to adapt to, resulting in certain acoustic scenarios. Low wakeup rate and high false wakeup rate degrades user experience

Abstract

The invention discloses an awakening method and device of intelligent equipment, electronic equipment and a medium. The method comprises the steps of obtaining a voice signal collected by the intelligent equipment, and determining a wake-up probability that the voice signal contains a wake-up word; acquiring target feature information of the voice signal, inputting the target feature information into a pre-trained threshold model, and determining a target wake-up threshold corresponding to the target feature information; and if the wake-up probability of the voice signal is greater than the target wake-up threshold, waking up the intelligent equipment. According to the method, the awakening rate of the intelligent equipment is improved, and the false awakening rate is reduced, so that theuser experience is improved.

Description

technical field [0001] The present application relates to the technical field of voice processing, and in particular to a method, device, electronic device and medium for waking up a smart device. Background technique [0002] At present, there are more and more types of smart devices, and their applications are becoming more and more extensive. Smart devices usually include smart robots, smart speakers, etc. [0003] The voice wake-up model can be installed on the existing smart device. After receiving the specific wake-up word sent by the user, such as "Xiaobao Xiaobao" or "Xiaobei Xiaobei", the smart device switches to the wake-up state, and then the smart device can recognize the user's sent , and play the multimedia resources requested by the user. The voice wake-up models on existing smart speakers, smart air conditioners and other smart devices are generally released uniformly, that is, the voice wake-up models have the same fixed voice wake-up threshold. The voice...
