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

Abstract

The invention relates to a voice awakening method and device. The method comprises the following steps of determining the awakening voice of the awakening words received by each intelligent device ina plurality of intelligent devices; obtaining the noise data obtained by each intelligent device; selecting a target awakened device from the intelligent devices according to the awakening voice received by the intelligent devices and the noise data obtained by the intelligent devices; and responding to the awakening voice through the target awakened device. According to the technical scheme, theawakening voice and the noise data of the intelligent devices can be combined at the same time, the determination accuracy of the awakened device is improved, then the awakening accuracy is improved,and the situation that other intelligent devices in the multiple intelligent devices serve as the devices really needing to be awakened to be awakened by mistake is avoided.

Description

technical field [0001] The invention relates to the technical field of voice processing, 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 w...
