Dollar Tree has a voice-controlled lamp for $1.25. Turn ON-OFF, DIM, Brightness & Color. 

There are programable voice chips that will do that, but they cost more than $1.25.

2:32 into the video the UPC code is shown.

@@Robothut Many thanks! I forgot it was there, and he apparently glossed over it!

The driver fets could drive a 5 volt relay coil or a solid state AC or DC relay to control any load you can think of. Just shot a second video where I control two DC gearmotors instead of the LEDs.

Yes, I saw that price error as well. Changed it.

Yes, I saw Clives video and comment back then on the commands. So far, I have not found more, but that does not mean they are not there. The instruction sheet is also in Spanish but the commands in the Spanish instructions are in English, so maybe only the commands listed are there. Now I wonder if the chip could be reprogramed.

@@Robothut It's so difficult to filter the words, I wouldn't be surprised if there was a huge database needed to achieve the task And that changing a command won't be trivial.

@@mrwoodandmrtin I agree. It is amazing that they got it down to a single chip to decode the words and MIC input as well as the function output drivers.

@@Robothut And all for that super low cost, including shipping to the US...!

@@mrwoodandmrtin Just amazing.

True, but that was not the point of the video. The voice control chip for $1.25 was what I was interested in.

Worth a try.

Dang it. $1.25 shot to hell. I lucked out, I have had 2 of them and they both work.

Depending on the application I would say, YES.
