Embodiment Construction

[0034] Hereinafter, the present invention will be described in detail by illustrating various embodiments of the invention by way of drawings. However, inventive concepts may be embodied in many different forms and should not be construed as limited to the illustrative embodiments set forth herein. Furthermore, the same reference numbers may be used to denote similar elements in the drawings.

[0035] First, see figure 2 , figure 2 It is a functional block diagram of an electronic device with a voice wake-up function provided by an embodiment of the present invention. In this embodiment, the electronic device 2 includes a host system HS, a microphone Mic, a microphone preamplifier 200 , a pre-signal detector 210 and a key speech determination circuit 20 . Wherein, the host system HS, the microphone preamplifier 200, the pre-signal detector 210, and the key speech judgment circuit 20 may be implemented through pure hardware circuits, or through hardware circuits combined w...

Abstract

Embodiments of the present invention provide an electronic device with a voice wake-up function and an operating method thereof. The electronic device may detect the analog sound signal by using an additional pre-signal detector, and when the analog sound signal is determined to meet a preset condition, the pre-signal The detector then wakes up the analog-to-digital converter and the human speech detector. Therefore, when the host system of the electronic device enters the dormant state from the normal working state, the analog-to-digital converter and the human voice detector can enter the dormant state together to achieve the power saving effect.

Description

technical field [0001] The present invention relates to an electronic device and its operating method, and in particular to an electronic device with a wake-on-voice (Wake on Voice) function and its operating method. Background technique [0002] With the development of science and technology, the voice wake-up function has been widely used in various electronic devices, ranging from mobile phones to general household appliances, may have a voice wake-up function, and the so-called voice wake-up function refers to When the device is in the dormant state (also known as the standby state), the user can directly wake up the electronic device through human voice, so that the electronic device can escape from the dormant state and return to a normal working state. For example, see figure 1 , figure 1 It is a schematic functional block diagram of a conventional electronic device with a voice wake-up function. Such as figure 1 As shown, the electronic device 1 mainly includes a...
