Problems solved by technology

Take the scene where the smart speaker is very close to the wall as an example. When the smart speaker is close to the wall or even has obstacles on three sides, the echo caused by the wall and other obstacles will affect the smart speaker's judgment on the location and energy of the sound source, and then guide the smart speaker.

Embodiment Construction

[0048] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0049] In a home environment, it is likely that the speaker will be placed against a wall, on a bookshelf, etc., close to the wall or other objects. Take the scene where the smart speaker is very close to the wall as an example. When the smart speaker is close to the wall or even has obstacles on three sides, the echo caused by the wall and other obstacles will affect the smart speaker's judgmen...

Abstract

The present disclosure relates to an environment recognition method and device. It involves the field of intelligent terminals, and solves the problem that the intelligent speakers are affected by occluders and cause errors in speech recognition. The method includes: sending detection sound waves in at least one direction; receiving reflected sound waves reflected back after the detection sound waves reach the reflection interface in all directions; analyzing the reflected sound waves to identify surrounding obstructions. The technical solution provided by the present disclosure is applicable to smart devices, and realizes automatic recognition of obstacles around the devices.

Description

technical field [0001] The present disclosure relates to the field of smart terminals, and in particular to an environment recognition method and device suitable for smart speakers. Background technique [0002] Smart speakers interact with users through voice commands. Smart speakers generally have multiple built-in microphones, through omnidirectional radio, according to the change of sound energy, calculate the location of the sound source; and then use the directional amplified radio power to obtain a clearer sound for identification. [0003] However, in a home environment, it is likely that the speaker will be placed against the wall, on a bookshelf, etc., close to the wall or other objects. Take the scene where the smart speaker is very close to the wall as an example. When the smart speaker is close to the wall or even has obstacles on three sides, the echo caused by the wall and other obstacles will affect the smart speaker's judgment on the location and energy of ...
