It is disclosed a voice pickup method and apparatus for an intelligent rearview mirror, an electronic device and a computer readable storage medium which relates to the technical field of vehicle-mounted equipment, and may be used in the field of automatic driving technologies. A voice pickup implementation of the intelligent rearview mirror according to some embodiments includes: acquiring an image of the interior of the vehicle; determining the position of a person in the vehicle with the image of the interior of the vehicle; and adjusting a beamforming direction of a microphone array according to the position of the person in the vehicle.

Voice pickup method for intelligent rearview mirror, electronic device and storage medium

A method and an apparatus detect an echo delay. If an electronic device plays an audio and a counter is in an on state, an Nrecording data block received after the counter is turned on is acquired, where the Nrecording data block is a currently received recording data block, and N is greater than 1. Matching is performed between the Nrecording data block and a reference data block that is in a buffer, where the recording data block and the reference data block are data blocks with target duration. After the counter is on, the buffer buffers an audio data block played by the electronic device. If the Nrecording data block matches the reference data block in the buffer, a counting value is acquired. The counter performs counting if the recording data block does not match the reference data block. An echo delay is determined based on the target duration and the counting value.
