Many AI speakers are on the rise these days. The main function of the AI speaker is to convert the voice into data and the data can be used to execute the program.
A running program is used to get weather information or to play music. You don’t have to think of it as hard because AI speakers currently are not involved with artificial intelligence.
I would like to inform you the WIZnet products that can be played music or recognized the voice.
