Embodiment Construction

[0033] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary, and are intended to explain the present application, and should not be construed as limiting the present application.

[0034] At present, for the Android system, the APP or the Software Development Kit (Software Development Kit, referred to as SDK) obtains the audio data after signal processing through the recorder module, and at the same time passes the processed audio data to the wake-up algorithm for wake-up detection. Follow-up wake-up control is performed according to the detection result. For the Linux system, the APP or SDK obtains the audio data generated by the task of the signal algorithm through an independent process task, and at...

Abstract

The present application proposes a voice wake-up method and device, wherein the method includes: obtaining the audio data currently collected by the electronic device through the audio and video hardware abstraction layer interface of the electronic device; performing noise reduction processing on the collected audio data to generate the audio data to be detected Audio data: perform wake-up word detection on the audio data to be detected, and determine whether the audio data to be detected contains a wake-up word; if the audio data to be detected contains a wake-up word, perform wake-up processing on the electronic device. The method can improve voice wake-up efficiency and reduce wake-up delay.

Description

technical field [0001] The present application relates to the technical field of voice recognition, in particular to a voice wake-up method and device. Background technique [0002] At present, the voice wake-up technology usually sends the collected audio data to the application program (Application, APP for short) through the audio data transmission link after signal processing, and then the APP invokes the wake-up algorithm to perform wake-up detection on the processed audio data. The wake-up control is performed on the APP according to the detection result. [0003] However, this wake-up method has a long wake-up delay. Contents of the invention [0004] The present application proposes a voice wake-up method and device, so as to improve voice wake-up efficiency and reduce wake-up delay. [0005] The embodiment of the first aspect of the present application proposes a voice wake-up method, including: [0006] Acquiring the audio data currently collected by the elect...
