Problems solved by technology

[0003] However, in the above solution, the speech recognition device cannot distinguish between noise and the user's voice. If the collected sound only includes the noise in the environment, the speech recognition device will also analyze the noise, which wastes device resources.

Embodiment approach

[0159] As an embodiment, the device further includes:

[0160] A first interaction module (not shown in the figure), configured to perform a first type of interaction task based on the acquired sound and the lip image.

[0161] As an embodiment, the apparatus further includes: a first extraction module and a second extraction module (not shown in the figure), wherein,

[0162] a first extraction module, configured to perform feature extraction on the lip image when it is determined that the person has lip movements, to obtain the lip language feature of the person;

[0163] The second extraction module is used to perform feature extraction on the acquired voice to obtain the voice feature of the person;

[0164] The first interaction module is specifically configured to: input the lip language feature and the voice feature into a pre-trained recognition network, and perform the first type of interaction task based on the output result.

[0165] As an implementation manner, t...

Abstract

The embodiment of the invention provides a voice acquiring method, a voice acquiring device, a voice acquiring system, and a facility. The method comprises the following steps: analyzing a lip image of a person, and acquiring voice collected by a voice acquiring facility under the condition that the judgement shows that the person has lip movements. Understandably, if the person has lip movements,the person is likely to be under the speaking state with the mouth open, under the circumstance, when the voice collected by the voice acquiring facility is acquired, the probability that only noiseis acquired is reduced.

Description

technical field [0001] The present invention relates to the technical field of data processing, and in particular, to a sound acquisition method, device, device and system. Background technique [0002] In the field of smart home, in-vehicle equipment and other fields, speech recognition is usually required to facilitate users' control of home equipment, in-vehicle equipment, and the like. Existing recognition solutions generally include: a voice recognition device collects sounds in the environment, analyzes the collected sounds, and obtains control instructions or other interactive information issued by the user. [0003] However, in the above solution, the speech recognition device cannot distinguish the noise from the user's voice. If the collected sound only includes noise in the environment, the speech recognition device will also analyze the noise, which wastes device resources. SUMMARY OF THE INVENTION [0004] The purpose of the embodiments of the present inventi...
