Abstract

The invention provides a speech pickup device and a multimedia device. The device comprises an image acquisition unit which is used for acquiring an image, a face recognition unit which is electrically connected with the image acquisition unit to carry out face recognition on the acquired image, a speech acquisition unit which is used for acquiring a speech signal, a steering adjusting unit which is connected with the speech acquisition unit to adjust the orientation of the speech acquisition unit, and a processing control unit which is electrically connected with the image acquisition unit, the face recognition unit, the speech acquisition unit and the steering adjusting unit. The processing control unit controls the steering adjusting unit to align the speech acquisition unit with the orientation of a face when the face recognition unit recognizes that the face is in the acquired image and controls the speech acquisition unit to acquire the speech signal of the orientation of the face. The device is capable of automatically steering to carry out oriented speech pickup on the speech signal sent by a user according to the face position of the user to reduce external noise interference.

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.
