Embodiment Construction

[0069] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0070] figure 1 It is a flowchart of a human-computer interaction method shown according to an exemplary embodiment, which is applied to an electronic device equipped with a camera, such as figure 1 As shown, the human-computer interaction method includes the following steps 101 to 105:

[0071] In step 101, an environmental sound signal is acquired.

[0072] For example, the electr...

Abstract

The present disclosure relates to a human-computer interaction method and device. The method includes: acquiring the sound signal of the environment; when it is determined that the sound signal of the environment is greater than or equal to a preset value, acquiring a lip state signal and a voice signal through the camera; wherein the lip state signal includes lip movement state and non-lip movement state; according to the moment when the lip movement state occurs and the time when the lip movement state occurs, determine the speech signal to be recognized from the speech signal; identify the speech signal to be recognized; When it is determined that the voice signal to be recognized matches the preset signal, the dialogue system is started. When the electronic device is in a noisy environment, the technical solution can segment the speech signal obtained in the noisy environment according to the lip state signal, accurately obtain the wake-up word, realize accurate wake-up of the electronic device, and improve user experience.

Description

technical field [0001] The present disclosure relates to the technical field of human-computer interaction, and in particular, to a method and device for human-computer interaction. Background technique [0002] With the continuous development of information technology, electronic devices such as smart large screens or hardware robots with screens have gradually become popular. [0003] In related technologies, when waking up an electronic device, the user needs to input a wake-up word by voice, and the electronic device matches the wake-up word input by the user with the preset wake-up word, and actively wakes up the electronic device when it is determined that the wake-up word matches the preset wake-up word Electronic devices, users can realize human-computer interaction with electronic devices through voice. [0004] However, if the above-mentioned method of waking up the electronic device is noisy, the voice signal received by the electronic device will be cluttered, a...
