Abstract: The present disclosure provides a method and an apparatus for waking up via a speech. The method includes: obtaining audio data currently collected by an electronic device through an audio-video interface on a hardware abstraction layer of the electronic device; performing noise reduction processing on the collected audio data to generate audio data to be detected; performing wake-up phrase detection on the audio data to be detected to determine whether the audio data to be detected includes a wake-up phrase; and performing wake-up processing on the electronic device in response to determining that the audio data to be detected comprises the wake-up phrase.

Abstract: The present disclosure discloses a voice activity detection method and apparatus, an electronic device and a storage medium, and relates to the field of artificial intelligence, such as deep learning, intelligent voices, or the like. The method may include: acquiring time-aligned voice data and video data; performing a first detection of a voice start point and a voice end point of the voice data using a voice detection model obtained by a training operation; performing a second detection of a lip movement start point and a lip movement end point of the video data; and correcting a result of the first detection using a result of the second detection, and taking a corrected result as a voice activity detection result. The solution of the present disclosure may improve accuracy of the voice activity detection result, or the like.

Abstract: A digital control laser automatic tooth preparation method and device and a tooth positioner are provided. The device includes an intra-oral three-dimensional scanner, a dental laser, an oral working end, an oral and maxillofacial cone beam CT scanner, a computer, a tooth positioner, a negative-pressure suction device and a real-time monitoring device. The computer is connected respectively with the intra-oral three-dimensional scanner, the dental laser, the oral working end, the oral and maxillofacial cone beam CT scanner, the negative-pressure suction device, and the real-time monitoring device. The dental laser is connected with the oral working end of the digital control laser tooth preparation control system through a light guiding arm (1). The oral working end of the digital control laser tooth preparation control system is connected with the tooth positioner and the real-time monitoring device. The negative-pressure suction device is connected with the tooth positioner.

Abstract: The invention relates an electric sharpener, comprises a main frame, a main shaft, a motor, a transmission wheel, a grinding stone, and an electric control circuit. The motor is mounted on an angular frame which in turn is mounted on the main frame. The transmission wheel is fixed to an end of the main shaft, and the output shaft of the motor is tightly pressed against the periphery of the transmission wheel so as to drive it. A tool rest is fixed onto the main frame in a vertical or horizontal mounting orientation. A water vessel is fixed to the main frame, and the lower portion of the grinding stone dips into the water contained in the water vessel. Special clamps and attachments for grinding different tools are provided. The electric sharpener can be used for grinding various woodworking or household tools.
