Embodiment 1

[0053] see figure 1 , in Embodiment 1 of the present invention, a structural diagram of a speech recognition system for an intelligent robot provided in the embodiment of the present invention, including: a sound acquisition device 100 and an analysis device 200, the sound acquisition device 100 and the analysis device 200 communication connection;

[0054]The sound acquisition device 100 is used for acquiring voice, judging the source location according to the sound intensity of each position, and adjusting the angle of acquiring the sound;

[0055] The analysis device 200 is configured to receive the sound data transmitted by the sound acquisition device 100, and then recognize the sound data to obtain a recognition result. A wired connection and a wireless connection are set between the sound acquisition device 100 and the analysis device 200. Both connection methods are set to ensure stable data transmission between the two, and a wired connection is set to realize high-s...

Embodiment 2

[0058] see figure 2 The main difference between Embodiment 2 and Embodiment 1 is that the sound acquisition device 100 includes a comparison module 110 , a multi-angle sound acquisition module 120 , a sound acquisition module, a sound acquisition module 130 and an execution module 140 .

[0059] The multi-angle sound acquisition module 120 is used to acquire multiple intensity sound sources for intensity comparison from multiple angles, and send multiple intensity sound source data to the comparison module 110;

[0060] The comparison module 110 is used to receive multiple intensity sound source data sent by the multi-angle sound acquisition module 120, and then compare multiple intensity source data to obtain intensity direction data;

[0061] The execution module 140 is used to receive the intensity direction data obtained by the comparison module 110, and then adjust the sound acquisition direction of the sound acquisition module 130 to ensure that the sound acquisition mo...

Abstract

The invention is suitable for the technical field of voice recognition, and provides a voice recognition system for an intelligent robot. Comprising a sound acquisition device and an analysis device, and the sound acquisition device is in communication connection with the analysis device; the sound acquisition device is used for acquiring voice, judging a source position according to the sound intensity of each position and adjusting a sound acquisition angle; and the analysis device is used for receiving the sound data transmitted by the sound acquisition device and then identifying the sound data to obtain an identification result. The sound acquisition device is used for judging the position of the sound source to obtain the position of the maximum sound source, and then the sound is obtained and transmitted to the analysis device for recognition, so that the intensity of the obtained sound can be ensured, and the recognition accuracy is ensured. According to the invention, the accuracy of sound recognition is ensured, and the position of the sound source is automatically searched.

Description

technical field [0001] The invention relates to the technical field of voice recognition, in particular to a voice recognition system for intelligent robots. Background technique [0002] A robot is a machine device that performs work automatically. It can accept human commands, run pre-programmed programs, and act according to principles and programs formulated with artificial intelligence technology. Its task is to assist or replace human work, such as production, construction, or dangerous work, and can be divided into general robots and intelligent robots. A general robot refers to a robot that does not have intelligence but only has general programming capabilities and operating functions. An intelligent robot must have at least the following three elements: one is the sensory element, which is used to understand the state of the surrounding environment; the second is the movement element, which reacts to the outside world; what action to take. [0003] Voice is the ...
