Embodiment 1

[0036] Such as figure 1 As shown, the invention provides a microphone array, comprising:

[0037] Several microphone array collection nodes 11 and one information gathering node 12 are arranged in a distributed manner.

[0038] The plurality of microphone array collection nodes 11 all establish a communication connection with the information aggregation node 12 through a wireless network.

[0039] Wireless network includes: 802.11 wireless wifi, Bluetooth, 2G / 3G / 4G mobile data and Zigbee.

[0040] When using a wireless network, capacity expansion is easier, and the layout does not need to consider the issue of wiring. When expansion is required, it is only necessary to add microphone array collection nodes 11 and establish a wireless network connection between the newly added microphone array collection nodes 11 and the information aggregation node 12 .

[0041] Each microphone array collection node 11 is provided with a single microphone audio collection module 111 and a w...

Embodiment 2

[0049] Such as figure 2 As shown, the invention provides a microphone array, comprising:

[0050] Several microphone array collection nodes 11 , an information convergence node 12 and an information relay node 13 are arranged in a distributed manner.

[0051] A plurality of microphone array collection nodes 11 all establish communication connections with the information aggregation node 12 through a wireless network; wherein, the wireless network includes: 802.11 wireless wifi, Bluetooth, 2G / 3G / 4G mobile data and Zigbee.

[0052] A communication connection is established between the information relay node 13 and the information aggregation node 12 through a wireless network; wherein, the wireless network includes: 802.11 wireless wifi, Bluetooth, 2G / 3G / 4G mobile data and Zigbee.

[0053] The information aggregation node 12 is an aggregation gateway with a wireless communication function. The information relay node 13 is a relay gateway with a wireless communication function...

Embodiment 3

[0064] Such as image 3 As shown, the embodiment of the present invention provides a voice control system, including:

[0065] Embodiment 1 provides a microphone array 1 and a voice control unit 2 . The microphone array 1 is electrically connected with the voice control unit 2 . In other embodiments, the microphone array 1 may be the microphone array provided in Embodiment 2.

[0066] The microphone array 1 is used for directional collection of multiple sound sources.

[0067] The voice control unit 2 performs voice recognition on the audio signal uploaded by the microphone array 1 and controls the device to execute voice commands.

[0068] Specifically, the voice control unit 2 is divided into a voice recognition module 21, a signal processing module 22 and a control module 23; the voice recognition module 21 matches the voice information collected with preset keywords, and then the signal processing module 22 performs judgment and recognition , and the control module 23 ...

Abstract

The invention provides a microphone array, and the microphone array comprises a plurality of microphone array collection nodes and one information aggregation node, which are set in a distributed manner. The plurality of microphone array collection nodes are respectively in communication connection with the information aggregation node through a wireless network. Each microphone array collection node is provided with one microphone unit audio collection module and a wireless communication module. The information aggregation node is a gateway with a wireless communication function. Each microphone array collection node is used for collecting the voice information, and transmitting the voice information to the information aggregation node through the corresponding wireless communication module. The information aggregation node carries out the processing of the received voice information, and transmits the processed voice information to a voice control unit. The invention also provides avoice control system comprising the above microphone array, and the system can achieve the multi-room and cross-room voice control. The voice collection and a control terminal are separated, thereby effectively breaking the constraint of distance.

Description

technical field [0001] The invention belongs to the technical field of microphone sound pickup, and in particular relates to a microphone array and a voice control system. Background technique [0002] With the advancement of intelligent technology, voice recognition and voice interaction are more and more applied to intelligent products, and voice acquisition becomes crucial. In addition to the performance of the recognition engine, how the sound can be collected at any place for the subtraction composed of multiple rooms will greatly improve the convenience and ease of use of voice control. At present, the microphone is generally installed directly on the execution device, which can only meet the needs of basic scenarios, but is powerless for multi-room and cross-room voice operations. It cannot pick up sound from a long distance (beyond 5 meters); the current sound pick-up and the voice control terminal are combined into one, resulting in a limited recognition range of t...
