Embodiment 1

[0024] Such as figure 1 As shown, this embodiment provides a robot 1 including a sound pickup module 10 and a main control module 20 .

[0025] The sound pickup module 10 is electrically connected to the main control module 20, and the sound pickup module 10 includes a microphone array 11, and the microphone array 11 includes N microphones; where N≥3 and N is an integer.

[0026] N microphones are evenly distributed around the body of the robot 1 , and the main control module 20 acquires N channels of audio data collected by the microphone array 10 , and performs sound source localization and sound pickup based on the audio data.

[0027] In one embodiment, the above sound pickup device 10 further includes a small MIC board 12 .

[0028] The MIC small board 12 is electrically connected to the microphone array 11 and the main control module 20 respectively.

[0029] The MIC small board 12 performs analog-to-digital conversion on N channels of audio data collected by the micro...

Embodiment 2

[0046] Such as Figure 4 As shown, this embodiment provides a voice processing method based on the robot provided in Embodiment 1, which specifically includes:

[0047] Step S101: collect audio data through N microphones of the sound pickup module.

[0048] In a specific application, audio data is collected through N microphones installed on the robot body. The above N microphones are distributed on a circle centered at any point on the longitudinal axis of the body of the robot, the circle is perpendicular to the longitudinal axis, N≥3 and N is an integer.

[0049] In one embodiment, the above-mentioned N microphones are 6 microphones, and the 6 microphones are arranged on the neck of the robot, and the 6 microphones are distributed on a circle centered at any point on the longitudinal axis of the robot body, and the circle is perpendicular to the longitudinal axis of the robot. Axis, 6 microphones form a circular 6MIC array.

[0050] Step S102: Send N channels of audio da...

Abstract

The invention is suitable for the technical field of electronics, and provides a robot and an audio processing method thereof. The robot comprises a pickup module and a main control module; the pickupmodule is electrically connected with the main control module, the pickup module comprises a microphone array, and the microphone array comprises N microphones, wherein the N microphones are uniformly distributed around the body of the robot, and the main control module acquires N paths of audio data acquired by the microphone array and performs sound source positioning and sound pickup based onthe audio data. A microphone array composed of N microphones which are annularly and uniformly distributed is arranged on a robot body of the robot to perform audio data acquisition; the acquired N paths of audio data and reference audio data are transmitted to the main control module; sound source positioning and sound pickup are achieved based on the audio data through the main control module, 360-degree awakening and sound source positioning of the robot can be supported, formation of directional beams can also be supported, sound pickup is achieved, a microphone hole does not need to be formed in the head of the robot, and the attractiveness of the robot cannot be affected.

Description

technical field [0001] The invention belongs to the field of electronic technology, and in particular relates to a robot and an audio processing method thereof. Background technique [0002] When designing a robot, if the position of the microphone array is not correct, it will affect the voice interaction effect. Because the most basic requirement and precondition of the beam-forming of the microphone array is: the sound directly reaches each microphone in the microphone array. Therefore, if the circular microphone array is placed on the neck of the robot, the neck of the robot will block the microphone behind the neck, causing the sound to be reflected by the neck and cannot reach the microphone behind the neck of the robot, thereby affecting the sound pickup effect. [0003] Aiming at the above problems, the current market usually puts the ring microphone on the head of the robot or uses the ring microphone array and the linear microphone array at the same time. Sound s...
