I want to build a voice/sound recording circuit that when triggered will play its pre-recorded sound through an amplifier circuit.The amplifier circuit will have a relay on the input so after the voice/sound recorder is played,it will switch back and resume normal operation from it original input.I have a few circuit ideas in my head,but am unsure which voice/sound recording chip would be best suited for the job.The sound is only a few seconds long,so it does not need much memoy.Mostly what I am looking for is a chip that has a output that will change the relays inputs to the amp.,when the voice chip is activated.Any ideas??,thanks for the help...

 

ISD chips can do this. Nowadays ISD is formerly WINBOND.

Thanks for the reply,I will check into that IC.Is there an output on it that will go high when it is playing so I could trigger another circuit.No big deal if there isn't,I would have to just build another circuit to do that task.Thanks again...

 

I've not considered the datasheet, but EOM= end of message.

 

Thanks again.I will order this chip when I get the chance...

I want to build a circuit which can re-record voice atleast up to 10min

so please guide me how can i go forward

 

Winbond sold the Chipcorder line to Nuvoton:

Will I get any other way of making a device which can re-record the voice and it should be capable of playback.

 

Just activate the amplifier simultaneously with the playback button. Plan a 100 to 200ms delay for the message when recording.

i was thinking about this too... i see on schematic aux in. Can i use line level signal on the aux in instead of mic?
