Problems solved by technology

[0003] However, this method does not distinguish signal energy but blindly relies on the total value of signal energy received by the device during the wake-up word time period. Therefore, the correct rate of wake-up response will drop sharply in a noisy environment. For example: if a certain If a device is closer to the noise source but farther away from the user, it will receive noise with greater energy when it receives the wake-up word, which may cause its energy to be higher than the energy received by the nearest device and be misjudged as the nearest device. As a result, the device that is far away is mistakenly regarded as the nearest device to respond to the wake-up voice

Embodiment Construction

[0050] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0051] In order to solve the above technical problems, the embodiment of the present invention provides a voice wake-up method, which can be used in a voice wake-up program, system or device, and the execution subject corresponding to the method can be a terminal or a server, such asfigure 1 As shown, the method includes steps S101 to S104:

[0052] In step S101, determine the wake-up voice of t...

Abstract

The invention relates to a voice awakening method and device. The method comprises the steps of determining awakening voice of awakening words received by each to-be-awakened device in a plurality ofto-be-awakened devices, determining noise data obtained by the to-be-awakened devices, selecting a target awakened device from the to-be-awakened devices according to the awakening voice received by the to-be-awakened device and the noise data obtained by the to-be-awakened device, and responding to the awakening voice through the target awakened device. Through the technical scheme of the invention, the determination accuracy of the awakened device can be improved, the awakening accuracy is further improved, and other to-be-awakened devices in the to-be-awakened devices is prevented from being mistakenly awakened as a device which really needs to be awakened.

Description

technical field [0001] The invention relates to the field of voice technology, in particular to a voice wake-up method and device. Background technique [0002] At present, with the popularization of voice smart devices, multiple different devices using the same wake-up word may appear in the home environment (such as: TVs, refrigerators, air conditioners, washing machines, etc. are all awakened by the same wake-up word), and this scenario is very There may be a situation of "every response to one call". In order to solve this problem, the simplest solution is: select the nearest device according to the signal energy of the wake-up word received by each device, that is, the farther the sound travels, the more serious the energy attenuation will be. The wake-up word received by the nearest device of the user has the highest energy, and accordingly, the closest device with the highest energy is determined to be the device that needs to be woken up to respond to the wake-up voi...
