Embodiment Construction

[0029] In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0030] The current voice wake-up method is generally based on the voice recognition of the wake-up word, but the current voice wake-up scheme, when waking up the terminal by voice, mostly recognizes the user's input voice, detects whether the wake-up word is included, and executes the wake-up if it is included. Operations, such as unlocking, brightening the screen, etc. For example, if the wake-up word "Xiaoou Xiaoou" is pre-stored in the terminal, when the user says "Xiaoou Xiaoou", when the terminal obtains the voice input, if it recognizes the wake-up word contained in it, it will perform a screen brightening operation.

[0031] However, the inventors found that in a...

Abstract

The invention discloses a voice wake-up method and device, electronic equipment and a storage medium, and relates to the technical field of voice processing, and the method comprises the steps: obtaining an input voice collected by an audio collector; matching the input voice based on a first voice matching model to obtain a first probability output, the first probability output being used for indicating a probability that the input voice contains a specified text; obtaining at least one probability output output by the first voice matching model before the current first probability output, and taking the probability output as a second probability output; fusing the first probability output and the second probability output to obtain updated first probability output; taking the updated first probability output as a first matching result of matching the input voice by a first voice matching model; and if the first matching result indicates that the input voice contains the specified text, waking up a terminal. According to the method, the historical output and the current output are fused, so that the keyword recognition accuracy can be improved, and the false awakening rate is reduced.

Description

technical field [0001] The present application relates to the technical field of voice processing, and more specifically, to a voice wake-up method, device, electronic equipment, and storage medium. Background technique [0002] With the rapid development of voice processing technology, voice dialogue functions have appeared in terminals in people's daily life. Users can further control the terminal by inputting specific voices, such as waking up the bright screen, waking up to unlock, and waking up to start voice dialogue functions, etc. The terminal may receive multiple voices at the same time. In order to identify the voice used by the user to control the terminal, it generally detects whether the voice contains wake-up words, and wakes up again if there is. However, in actual use, the terminal is often awakened by mistake when the user does not say a wake-up word, that is, the false wake-up rate of voice wake-up is relatively high at present.
