Terminal and voice wake-up method

Abstract

The invention discloses a terminal which comprises a microphone, a main processor module, a co-processor module, wherein the microphone is connected with the co-processor module and is used for acquiring a first voice instruction when the main processor module is in a sleep state and inputting the first voice instruction into the co-processor module; the first voice instruction comprises first feature information; the co-processor module is connected with the main processor module and is used for presetting a second voice instruction comprising second feature information, comparing the first feature information of the acquired first voice instruction with the second feature information and outputting a wake-up instruction to the main processor module when a comparison error is smaller than a preset threshold; and the main processor module carries out activation after receiving the wake-up instruction, so that power consumption of the terminal is reduced.

Description

technical field [0001] The invention belongs to the technical field of terminals, and in particular relates to a terminal and a voice wake-up method. Background technique [0002] Speech recognition technology whose goal is to convert the lexical content of human speech into computer-readable input, such as keystrokes, binary codes, or character sequences. [0003] Led by Apple's Siri, voice assistants have sparked a wave of app adoption. With voice assistants, users only need to say their needs or instructions, and the device can execute them using voice recognition and machine learning, which greatly improves the user experience. [0004] However, most of the current solutions can only use the voice recognition function when the screen is on, and the function is relatively limited. Since the user's voice input needs to be recognized at any time during standby, the microphone of the mobile phone must always be in the working state, and at this time, as the main control un...

Problems solved by technology

[0004] However, most of the current solutions can only use the voice recognition function when the screen is on, and the function is limited.

Since it is necessary to recognize the user's voice input at any time during standby, the microphone of the mobile phone must always be in the working state, and at this time, as the main control unit of the mobile phone, it cannot be in deep sleep, the standby current of the mobile phone will be greatly increased, and the power consumption of the mobile phone will be increased.
