Problems solved by technology
[0004] Since the wake-up mode of the voice activity detection unit is relatively simple, it cannot adapt to various sound field environments. For example, in scenes with a lot of human voices such as bars, concerts or shopping malls, the voice activity detection unit is easily awakened by mistake, and the wake-up in this scene The frequency is much higher than the wake-up frequency in a quiet environment
Since the voice activity detection unit and the keyword detection unit are directly connected, and the voice activity detection unit is always in the listening state, the keyword detection unit is also always in the computing state, and it is easy to increase the power consumption of the smart device in the above-mentioned noisy environment

The invention relates to the technical field of voice wake-up, and discloses a voice wake-up mode adjusting method, a storage medium and electronic equipment. The adjusting method comprises the steps that the number of voice awakening times of a voice activity detection unit in a preset duration is obtained, and when the voice activity detection unit is in an awakening state, a keyword detection unit can be awakened to work; and the current wake-up mode of the voice activity detection unit is adjusted according to the voice wake-up times and a preset wake-up threshold. Since the voice wake-up frequency can reflect the external environment condition, the current wake-up mode of the voice activity detection unit is adaptively adjusted according to the external environment, so that the adjusted current wake-up mode is adaptive to the external environment, the frequency that the voice activity detection unit is easily awakened by mistake due to the use of a single wake-up mode is reduced, and the frequency that the keyword detection unit is awakened by mistake is reduced, so that the power consumption is reduced.
Description
technical field [0001] The invention relates to the technical field of voice wake-up, in particular to a method for adjusting a voice wake-up mode, a storage medium and electronic equipment. Background technique [0002] At present, most smart devices have a voice wake-up function. When the smart device is not used for a long time, it will automatically enter the sleep state. In the sleep state, smart devices can reduce power consumption and reduce power consumption. [0003] Existing smart devices are integrated with a voice activity detection unit (Voice activity detection, VAD) and a keyword detection unit (Keyword Spotting, KWS), the voice activity detection unit is used to detect whether the audio signal contains a voice signal, wherein the voice signal is the user If the sent signal contains a voice signal, the voice activity detection unit wakes up the keyword detection unit to work. The keyword detection unit is used to detect whether the voice signal contains a wa...
