Gregory Bay. Haier air conditioning Casady voice call need to say the voice "Gree Jinbei", you can wake up the voice function. The core of Haier Air conditioning Casady voice function is the addition of voice to NRK3301The recognition chip has the advantages of accurate recognition and far field noise reduction, and can support no more than 100 offline instructions.
Helcasati air conditioning voice function can be turned off. The Helcasati air conditioning voice function can be turned off by the air conditioning button or by voice or by the switch button in the lower left corner of the air conditioning control page. The core of Heilkasati air conditioning to achieve voice control function is to join the NRK3301 voice recognition chip, which is a 32-bit high-performance low-cost speech recognition IC with the advantages of accurate recognition far field noise reduction, which can support no more than 100 offline instructions.
<1, the principle of universality: the selected voice chip should be widely used and verified, and have been studied by a large number of experiments. 2) The principle of high cost performance: In the case of similar functions, performance and utilization, try to choose inexpensive voice chips to reduce costs. 3) The principle of convenient procurement: try to choose chips that are easy to buy and have a short supply cycle.
2, the main features of the voice chip are low power consumption, strong anti-interference ability, fewer peripheral devices, simple control, long voice storage time (some voice chips can save content for 100 years), power off without losing voice, some chips can also be heavyOverwrite speech content. Such as car reversing radar, bus stopping device, bank queue machine, voice toys, anti-theft system and other equipment are equipped with voice chips.
3, speech recognition chip compared with the traditional voice chip, the biggest feature of the speech recognition chip is to be able to voice recognition, it can make the machine understand the human voice, and can perform various actions according to the command, such as blinking eyes, moving the mouth (smart doll). In addition, the speech recognition chip also has the function of high-quality and high compression rate recording and playback, which can realize man-machine dialogue.
Universality principle Speech recognition chip : The selected speech chip should be widely used and verified speech recognition chip , after a large number of experiments. 2) The principle of high cost performance Voice recognition chip : In the case of similar functions, performance and utilization rate, try to choose inexpensive voice chips to reduce costs. 3) Procurement convenience principle: try to choose the capacityEasy to buy, short lead time chip.
