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.

so you need higher bytes bits per second.

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

Googling baby monitor could provide what you want.
