The voice recognition desk lamp is an intelligent lamp that operates through voice control, enabling various functions. This type of desk lamp is beneficial for children’s work, study, and reading, while also serving as a home decoration and can be used for emergency lighting. The development scheme for the intelligent voice desk lamp aims to meet these functionalities and address user needs. Moreover, there are many features of the intelligent voice desk lamp that can be customized.
Principle of the Intelligent Voice Recognition Desk Lamp Development Scheme
The voice recognition desk lamp is equipped with an ambient light sensor, a human infrared radiation sensor, and a microphone. The lamp uses the ambient light sensor to determine the room’s brightness to turn the human infrared radiation sensor on or off. By configuring the sensors, the lamp’s brightness can be controlled via voice commands, and the lamp can be switched on or off, achieving intelligent operation, energy saving, and environmental protection. This allows for widespread use in our daily lives, and the voice recognition desk lamp brings great convenience to our lives. The development of the voice recognition desk lamp is an important area in smart home solutions, and many users prioritize the intelligence of voice recognition desk lamps to achieve home automation.
Structure of the Intelligent Voice Recognition Desk Lamp
The structure of the voice recognition desk lamp includes a lamp base, a connecting rod, and a lampshade. The lampshade is mounted on the lamp base via the connecting rod. The lamp base features a touch display screen, which includes a USB interface and a headphone jack. There is a groove on the side of the lamp base that houses a power switch. The lamp base is equipped with speakers on both sides, and a microphone is located on top of the lamp base.
Functions of the Intelligent Voice Recognition Desk Lamp Development Scheme
Noise Filtering
Given that we live in a relatively noisy environment,
in far-field control, the user is at a certain distance from the smart speaker ECHO, and often the noise source is closer to the microphone than the person, which can complicate sound recording to some extent.
Decay Restoration
When sound is transmitted to the smart speaker ECHO microphone through external materials, it experiences some decay, and different frequency bands exhibit varying degrees of non-linear decay. To restore this sound, a relatively complex processing is required, utilizing SSP technology to achieve a pure sound effect, which is then transmitted to the voice control engine, enabling seamless natural voice interaction between humans and machines. The voice collected by the microphone array of the smart speaker ECHO undergoes signal processing and must match sufficiently with the voice control engine, ensuring that the voice control model aligns with the processed signal for optimal control effectiveness.
Reverberation Processing
In open spaces, when sound is emitted, sound waves encounter various materials in the space, leading to physical reflections. The different reflected sound waves converge at the microphone, resulting in a reverberation effect, thus requiring the sound to be processed to be relatively pure.
Main Functions
The primary functions of the voice recognition desk lamp include work reading, studying, and energy saving. The voice recognition desk lamp also serves as an indoor decoration, can control the lamp’s operational state via voice, and can automatically adjust brightness. It can adapt to the surrounding environment, play music, and include clock and touch functions. The voice recognition desk lamp also features an “emergency function,” which means it has a built-in power source that can provide emergency lighting in case of a power outage.
