Problems solved by technology

For example, when a parent uses a mobile phone to play the demonstration audio and video of the tutoring device, if the demonstration audio and video involves the demonstration steps of waking up the tutoring device, when the tutoring device captures the wake-up keywords in the demonstration audio and video, it will also mistakenly think that the user wakes up the tutoring Equipment requirements, this kind of false trigger operation will increase the power consumption of the whole machine of the tutoring equipment, which is not conducive to prolonging the battery life of the tutoring equipment

Abstract

The embodiment of the invention relates to the technical field of family education, and discloses a wrong touch prevention voice wake-up method and family education equipment. The method comprises thesteps: detecting whether a first voice signal comprising a wake-up keyword is received or not when the family equipment is in a sleep state; enabling the family equipment to extract the voice features of the first voice signal from the first voice signal if the first voice signal comprising the wake-up keyword is received; enabling the family education equipment to judge whether the first voice signal belongs to a specific voice segment or not according to the sound features of the first voice signal, wherein the specific voice segment at least comprises a demonstration audio and video or anaudio and video popularization advertisement comprising the wake-up keyword; and switching the sleep state of the family education equipment to an instruction waiting state if the first voice signal does not belong to the specific voice segment. According to the embodiment of the invention, the method can reduce the overall power consumption of the family education equipment, and facilitates the extending of the duration of the family education equipment.

Description

technical field [0001] The invention relates to the technical field of tutoring equipment, in particular to a false touch prevention voice wake-up method and tutoring equipment. Background technique [0002] At present, more and more primary and middle school students use tutoring equipment (such as tutoring machines) to assist their learning. Wherein, when the tutoring device is in a dormant state, the voice wake-up method can be used to wake up the tutoring device, so that the tutoring device can be in a state of waiting for instructions. Among them, the voice wake-up method is generally based on keyword recognition. As long as the voice signal captured by the microphone of the tutoring device contains the wake-up keyword, the tutoring device will switch its state from the dormant state to the waiting instruction state. [0003] It has been found in practice that the tutoring device will switch to the state of waiting for instructions as long as it recognizes that the cap...
