Manual switch control includes pressing elastic button switches, pressing toggle switches, knob-controlled switches or touch-controlled switches. With the development of intelligence, non-contact control switches have gradually developed. Non-contact control switches are generally divided into two types. One is to install various sensors and control the table lamps according to the sensed data. However, this requires the installation of various sensors according to various usage scenarios, which not only increases the cost of the table lamp, but also has a higher probability of false triggering; the other is through intelligent voice control, but the above-mentioned voice control generally requires intelligent networking or needs to realize intelligent control by calling the APP on the intelligent device.

With the development of intelligence, non-contact control switches have gradually developed. Non-contact control switches are generally divided into two types. One is to install various sensors and control the table lamps according to the sensed data. However, this requires the installation of various sensors according to various usage scenarios, which not only increases the cost of the table lamp, but also has a higher probability of false triggering; the other is through intelligent voice control, but the above-mentioned voice control generally requires intelligent networking or needs to realize intelligent control by calling the APP on the intelligent device. This control has a high degree of intelligence and a good control experience, but the above-mentioned intelligent control is not friendly to the elderly who are not familiar with intelligent devices, which reduces the usage experience of this group of people and is not conducive to the promotion of intelligently controlled table lamps.

[0038] A short press means pressing a button for less than two seconds, and a long press means pressing a button for more than or equal to two seconds.

[0039] In the use mode under the offline intelligent voice control mode, the user speaks a wake-up word or a command word, the human voice collection input circuit 44 controls the sound pickup module 20 to record the wake-up word or command word spoken by the user, processes it into text information through the MCU main control circuit 41, and stores it in the storage circuit 42, and the MCU main control circuit 41 calls the text information in the learning mode in the storage circuit 42 and compares it with the text information in the use mode in the storage circuit 42;

[0040] If they match, the MCU main control circuit 41 controls the power amplifier module 30 to play the prompt tone of the corresponding successful operation through the power amplifier circuit 43;

[0041] If there is no match, repeat the learning mode until a match is successful.

[0042] In the present invention, the above-mentioned scheme is adopted, which can not only meet the common needs of the elderly for turning on and off lights and adjusting brightness through the switch function button 11, but also meet the elderly's needs for intelligence through the learning function button 12.

[0044] In order to process the voice signal, the method of the MCU main control circuit 41 for processing the voice signal is as follows: the MCU main control circuit 41 filters and performs frame preprocessing on a section of original voice signal, extracts the voice signal to be analyzed from the original voice signal, and performs feature extraction to convert the extracted voice signal from the time domain to the frequency domain, providing a suitable feature vector for the acoustic model, and then calculating the score of each feature vector on the acoustic feature according to the acoustic feature in the acoustic model, and calculating the probability of the voice signal corresponding to a possible phrase sequence according to the relevant linguistics theory in the language model, and decoding the phrase sequence into corresponding text information according to the existing dictionary.

[0045] In order to reduce the size of the storage circuit 42, the number of wake-up words and command words of each type supported by the storage circuit 42 is less than or equal to 3. When the number of wake-up words and command words spoken by the user in the learning mode is greater than 3, the last number of wake-up words and command words supported by the storage circuit 42 is saved, thereby reducing the size of the storage circuit 42 and further reducing the production cost of this product.
