Embodiment 1

[0041] figure 1 It is a schematic diagram of a wake-up process of a smart device provided by an embodiment of the present invention, and the process includes the following steps:

[0042] S101: If the similarity between the acquired first voiceprint information of the voice information to be recognized and the pre-saved second voiceprint information is less than the first threshold, acquire at least A property information.

[0043] The method for waking up a smart device provided by an embodiment of the present invention is applied to an electronic device, and the electronic device may be the smart device itself that is woken up, or other devices other than the smart device that perform wake-up recognition and control the smart device to wake up , wherein the smart device includes smart home devices such as mobile terminals, smart speakers, and smart air conditioners, and other devices that perform wake-up identification and control the wake-up of the smart device may be devi...

Embodiment 2

[0066] In order to improve the wake-up rate of the smart device, on the basis of the above-mentioned embodiments, in the embodiment of the present invention, the attribute information includes volume information, frequency information, and information of a time period when the voice information is input.

[0067] In order to improve the wake-up rate of the smart device, at least one attribute information of the voice information to be recognized obtained by the electronic device other than the first voiceprint information includes volume information, frequency information and information of the time period when the voice information is input .

[0068] Wherein, the volume information refers to the acquired volume information of the voice information to be recognized, and the volume information may be the average volume of the voice information to be recognized, or the highest volume and the lowest volume of the voice information to be recognized ; The frequency information ref...

Embodiment 3

[0076] In order to improve the wake-up rate of the smart device, on the basis of the above embodiments, in the embodiment of the present invention, the judging whether the similarity between the first voiceprint information and the second voiceprint information is greater than a third threshold Previously, the method further included:

[0077] Determine the third threshold according to the matched target attribute information.

[0078]When the electronic device determines that at least one attribute feature of the voice information to be recognized has target attribute information whose similarity with the stored corresponding attribute information is greater than the corresponding second threshold, it indicates that the voice information to be recognized may be the target user voice information, in order to improve the wake-up rate of the smart device, a third threshold smaller than the first threshold may be used to continue judging the similarity of the voiceprint informati...

Abstract

The invention discloses a wake-up method, device, equipment and medium of an intelligent device, which are used to solve the problem of low wake-up rate of the existing intelligent equipment. Because in the embodiment of the present invention, when the similarity between the first voiceprint information of the voice information to be recognized and the saved second voiceprint information is less than the first threshold, by determining that the voice information to be recognized exists in other attribute information and the stored When the similarity of the corresponding attribute information is greater than the target attribute information corresponding to the second threshold, and the similarity between the first voiceprint information and the saved second voiceprint information is greater than the third threshold, it is determined that the smart device is awakened. The third threshold is smaller than the first threshold, because when the target attribute information exists, the threshold for voiceprint information comparison is reduced, thereby reducing the requirement for similarity between the first voiceprint information and the stored second voiceprint information, and improving The wake-up rate of smart devices.

Description

technical field [0001] The present invention relates to the technical field of natural language processing, in particular to a method, device, device and medium for waking up an intelligent device. Background technique [0002] In recent years, with the development of natural language processing technology, more and more fields have begun to apply speech recognition technology, such as smart speakers, smart robots, and smart phones. How to improve the wake-up rate has become a hot research topic in recent years. [0003] In the prior art, the smart device generally pre-records the voice information of the target user, obtains the voiceprint information of the voice information of the target user through the voiceprint model, and saves the voiceprint information. During subsequent wake-up detection, the voiceprint information of the collected voice information is obtained through the voiceprint model, and it is judged whether the voiceprint information matches the pre-saved v...
