Embodiment 1

[0063] figure 2 It is a schematic diagram of the specific implementation flow of the voice wake-up method provided in Embodiment 1 of the present invention, and the method is applied to figure 1 The electronic device 100 shown, its executive body is figure 1 Processor 103 in electronic device 100 is shown. see figure 2 As shown, the voice wake-up method provided in this embodiment may include the following steps:

[0064] Step S201 , if the voice activity detection process detects that the voice signal collected by the microphone 102 meets a first preset condition, trigger the processor 103 to read the data signal collected by the gravity sensor 101 .

[0065] In a specific implementation manner, the first preset condition is that the voice energy of the voice signal is greater than a second preset energy threshold. Wherein, the voice activity detection process and the microphone 102 are kept turned on when the electronic device 100 is in a standby state, and when the mi...

Embodiment 2

[0088] image 3 It is a schematic flow chart of the specific implementation of the voice wake-up method provided in Embodiment 2 of the present invention, and the method is applied to figure 1 The electronic device 100 shown, its executive body is figure 1 Processor 103 in electronic device 100 is shown. see image 3 As shown, the voice wake-up method provided in this embodiment may include the following steps:

[0089] Step S301, judging whether the voice activity detection process detects that the voice signal collected by the microphone 102 meets the first preset condition, and if it meets the first preset condition, proceed to step S302-1 and step S302-2 at the same time. The specific implementation manner of this step is the same as that of Embodiment 1, and will not be repeated here.

[0090]Step S302-1, judging whether to start the keyword recognition process in advance according to the degree of word loss allowed by the keyword recognition process and the startup s...

Abstract

The embodiments of the invention disclose a speech wake-up method and system, electronic equipment and a computer readable storage medium, and relates to the technical field of intelligent equipment. The method includes the steps that if the speech activity detection process detects that a speech signal collected by a microphone conforms to a first preset condition, a processor is triggered to read a data signal collected by a gravity sensor; according to the data signal, whether the speech signal is generated by speaking of a user wearing the electronic equipment or not is judged; if not, the speech signal is ignored; or if yes, the keyword recognition process is started, and if the speech signal is recognized to contain a preset speech instruction keyword, the electronic equipment is controlled to perform the corresponding function. According to the embodiments, energy consumption of the electronic equipment can be saved, the electronic equipment can be avoided being woken up by mistake; and in addition, no special bone-conduction microphone or other contact microphone is required, the cost is low, an algorithm is simple and practical, the accuracy is high, and consumed resources are few.

Description

technical field [0001] The invention of the present application belongs to the technical field of voice processing, and in particular relates to a voice wake-up method, system, electronic equipment and computer-readable storage medium. Background technique [0002] With the development of science and technology, various electronic devices generally have a voice wake-up function. By presetting a wake-up word in the device or software, when the user sends out the voice command, the device will wake up from the sleep state. [0003] The traditional voice wake-up solution is to obtain the audio signal collected by the microphone through Voice Activity Detection (VAD), and count the voice energy according to the audio signal. When the voice energy is greater than the preset threshold, the processor is triggered to start keyword recognition. , to determine whether the audio signal is a language instruction issued by the user. This voice wake-up scheme does not take into account w...
