Problems solved by technology

[0003] However, in the process of researching and practicing the existing technology, the inventors of the present invention found that the prior art generally uses voice online intelligent control of household equipment, but this method has the following defects: an online voice recognition system is required as control basis, and the current online speech recognition system is expensive; at the same time, when using online speech recognition, it needs to rely on network connection. Once the network is disconnected, the speech recognition system cannot be used normally; in addition, due to the certain delay of the network, As a result, the efficiency of online speech recognition cannot be guaranteed, which affects user experience

[0044] see Figure 1-3 .

[0045] Such as figure 1 As shown, the present embodiment provides an offline voice control method based on ZIGBEE wireless technology, which at least includes the following steps:

[0046] S101. After receiving a user's voice input signal in real time through a microphone pickup, send the voice input signal to a DSP voice processing chip.

[0047] Specifically, for step S101, after the voice collection system of the device collects the user's voice command words, the voice analog signal is converted into a digital signal by the voice signal analog-to-digital conversion circuit and then input to the voice processing dedicated DSP chip.

[0048] S102. Perform front-end processing, acoustic feature extraction processing, model training, and decoding processing on the voice input signal successively through the DSP voice processing chip to obtain an optimal recognition result.

[0049] Specifically, for step S102, such as figure 2 As shown, the DSP ...

[0091] Such as Figure 4 As shown, the present embodiment provides an offline voice control system based on ZIGBEE wireless technology, including:

[0092] The voice collection module 100 is configured to receive the user's voice input signal in real time through the microphone pickup, and send the voice input signal to the DSP voice processing chip.

[0093] Specifically, for the voice collection module 100, after the voice collection system of the device collects the user's voice command words, the voice analog signal is converted into a digital signal by the voice signal analog-to-digital conversion circuit and then input to the voice processing dedicated DSP chip.

[0094] The speech recognition module 200 is used to sequentially perform front-end processing, acoustic feature extraction processing, model training and decoding processing on the speech input signal through the DSP speech processing chip to obtain an optimal recognition result.

[0095] Specifically, for the...

Abstract

The invention discloses an offline voice control method and system based on a ZIGBEE wireless technology and a storage medium, and the method comprises the steps: receiving a voice input signal in real time through a microphone pickup, and transmitting the voice input signal to a DSP voice processing chip; carrying out front-end processing, acoustic feature extraction processing, model training and decoding processing on the voice input signal in sequence through a DSP voice processing chip to obtain an optimal recognition result; matching with the voice instruction word list according to theoptimal recognition result, obtaining a corresponding scene control instruction after successful matching, and sending the scene control instruction to a ZIGBEE module; and sending the received corresponding scene control instruction to a gateway through the ZIGBEE module to allow the gateway to rebroadcast the scene control instruction to bound equipment for scene control so as to realize voice remote control of the equipment . According to the invention, through the ZIGBEE wireless ad hoc network technology, the problem of voice control equipment under the condition of no network is solved,and the defect of low voice control efficiency caused by network delay is overcome.

Description

technical field [0001] The invention relates to the field of smart home technology, in particular to an off-line voice control method, system and storage medium based on ZIGBEE wireless technology. Background technique [0002] With the continuous development of the Internet of Things technology, more and more intelligent devices have entered people's daily life. Users can control the corresponding lighting, curtains, air conditioners and other household devices online through voice to realize distributed voice control. [0003] However, in the process of researching and practicing the existing technology, the inventors of the present invention found that the prior art generally uses voice online intelligent control of household equipment, but this method has the following defects: an online voice recognition system is required as The cost of the current online speech recognition system is relatively high; at the same time, when using online speech recognition, it needs to r...
