Off line speech recognition chip IC intelligent speech control range hood solution supports customized development details

In daily life, we have seen many voice controlled lamps, but have you ever seen a voice controlled range hood?

The kitchen is a place for making delicious food, but it is also a disaster area hit by oil smoke. In China, every time we cook, we have to cook more than one soup. Sometimes because of time constraints, we cook more than one dish at the same time, which means that the cook may face such a situation: it's time to put soy sauce on one side of the cooking, and it's time to put salt on the soup on the other side. Just after adjusting the firepower of the gas stove, it's time to add food to the pot. Suddenly he remembered that the range hood is not on, He was suffering from the choking oil fume, so he had to spare his hand to control the range hood... At this time, the kitchen was like a battlefield, and the cooks were in a hurry. After a meal, you have already lost your strength.

At this time, it is much more convenient to use a range hood that can be controlled by voice. Just say to it: small branch, small branch, increase wind speed, reduce wind speed, turn on lighting and turn off lighting, all can be controlled by voice. When you are too busy to spare your hands, say "turn on the smoke machine" to it; It will wake up from its deep sleep and wait for your instructions; When you can't see the cooking situation clearly, say "turn on the lighting"; When frying dishes with heavy taste, say "increase the wind speed"; It will start to make efforts to "mop up" the kitchen lampblack; When you leave the kitchen, say "turn off the smoke machine" again. From frying to cooking, you only need to open your mouth in the whole cooking process, and you can enjoy a smoke-free and clean kitchen environment. Is such an obedient range hood particularly cool, convenient and desirable?

In order to break the homogenization of range hoods, some range hoods take mobile phone control as the selling point and design a new interaction mode, but it is weak in practical application. In the cooking process, who will pick up the mobile phone and control the range hood? Fandou technology's off-line voice control range hood solution enables the range hood to be "eloquent" and ensure that the "voice service capability" is always online without networking.
