Hi.
Any suggestions to implement a circuit that its output will change state -say from hi to lo- when a pre-defined audio voice message says something like (example) "turn off decoder" ?
No other phrases are to trigger any action, not to work as a complex voice recognition circuitry.
Only one phrase (digitized?) to compare to the input ?
Any dedicated chip capable of such, where a phrase gets recorded and listens for its equal input ?

 

I had looked into this application several years ago. But my memory had faded and I can’t recommend a specific chip.

But there are solutions.

With your recording and recognizing requirement. You’re likely looking at a module versus a single chip solution. Search for any of these alternatives.

• voice recognition module
• speech recognition module
• voice recognition chip
• speech recognition chip

 

You will have to investigate this. mBlock with added Microsoft Cognitive Services
extension added. I do not know if it handles just a word or phrase. If it can do
speech to text you could do this on PC platform with mBlock. V 3.4.12

The pic I extracted shows the block programming gui construction items for speech
recognition from the MS Extension.



I am doing some investigation in this area so cannot offer much advice.

Thanks, fellows; will follow suggestions.
