Problems solved by technology

Take the voice pickup technology as an example. At present, although the voice pickup devices circulating on the market can pick up the voice signals sent by the user, they usually also collect a large number of voice signals when picking up the voice signals sent by the user. The external noise is used for voice pickup, so that the voice signal picked up by the voice pickup device is mixed with a large amount of external noise, the corresponding voice recognition accuracy is not high, and the voice pickup distance is also very short

Abstract

The invention provides a voice pickup device and multimedia equipment. The device includes: an image acquisition unit for acquiring images; a face recognition unit electrically connected to the image acquisition unit to perform face recognition on the acquired images; a voice acquisition unit for acquiring voice signals; and a voice acquisition unit The steering adjustment unit is connected to adjust the orientation of the voice acquisition unit; the processing control unit is electrically connected with the image acquisition unit, the face recognition unit, the voice acquisition unit, and the steering adjustment unit. When the face recognition unit recognizes that there is a human face in the collected image, the processing control unit controls the steering adjustment unit to align the voice acquisition unit with the orientation of the human face, and controls the voice acquisition unit to receive the voice signal of the orientation of the human face. to collect. The device can automatically turn to pick up the voice signal sent by the user according to the position of the user's face, so as to reduce the interference of external noise.

Description

technical field [0001] The invention relates to the technical field of audio pickup, in particular to a voice pickup device and multimedia equipment. Background technique [0002] With the continuous development of audio pickup technology, the application of audio pickup technology is becoming more and more extensive. But as far as the audio pickup technology itself is concerned, there are still many technical problems to be solved. Take the voice pickup technology as an example. At present, although the voice pickup devices circulating on the market can pick up the voice signals sent by the user, they usually also collect a large number of voice signals when picking up the voice signals sent by the user. There is a lot of external noise mixed in the voice signal picked up by the voice pickup device, the corresponding voice recognition accuracy is not high, and the voice pickup distance is also very short. Contents of the invention [0003] In order to overcome the above...
