1. The principle of Xiaohong voice remote control is to convert the user's voice command into a digital signal through voice recognition technology, and then send the signal to the TV or other smart home devices through wireless communication technology, so as to achieve the control of the device. 2. Xiaohong voice remote control has a built-in high-precision voice recognition chip and wireless communication chip, which can quickly and accurately identify the user's voice command and convert it into a digital signal, and transmit the signal to the device through wireless communication technology. 3. The principle of Xiaohong voice remote control can not only be applied to the TV remote control, but also to the control of smart home devices, such as smart light bulbs, smart curtains, etc., to provide users with a more convenient smart home control experience.
principle
The voice recognition remote control removes unnecessary redundant information in the voice signal for speech recognition, retains information that can reflect the essential characteristics of the voice, and expresses it in a certain form.
The voice recognition remote controls combine them through standard finite state converter operations, building a converter from context-dependent phoneme substates to words.
