Voice Activated Switch, seeking project info
« on: April 07, 2013, 02:51:26 PM »
Hello, I'm looking for a project that may at one time been listed on this site:
    Voice Activated Switch

The diagram was re-posted here:
  newbielink:http://www.hobby-circuits.com/circuits/sensor/sound-sensor/443/voice-activated-switch [nonactive]

I'm a beginner & not clear on all the parts needed.
There was a description & a link back here. 

It began thus: "This circuit uses an MC2830 to form a voice activated switch ( VOX ). A traditional VOX circuit is unable to distinguish between voice and noise in the incoming signal. "

Thank you for your time.

The MC2830 IC is obsolete and has not been made for many years.
