Topic: How to use low cost transmitter and receiver to send voice over? (Read 1 time) previous topic - next topic

I have the following transmitter and receiver. I want to utilize them to send transmit voice over. For that do you need any external circuits made, if so what exactly do I need? If anyone has circuits can I use it, and any links would be helpful too.

<9.6 kbps for audio?
Would it be simpler to remotely trigger an MP3 player?

It's going to be difficult to squeeze audio into it.
Think of it as 960 bytes per second at most
What does Nyquist say?

Sampling frequency should be twice the actual frequency, i guess.

..and telephony quality (ie not great quality) bandwidth is around 3kHz.
Do the arithmetic.

What exactly do you want to do?
Synthesis could be an answer.
Or hack a cheap walkie-talkie

Just make arduino detect a baby voice (already accomplished it), after it detects send the baby voice using the transmitter to the receiver. I dont know how i can do it? Like whether I need any additional circuits?
