I want to make mic + speaker real time talking using arduino , is this possible ? and what materials that I do?
I mean I want to make a microphone + speaker like in a party and like in a DJ... when the singer sings into the microphone the singer's voice is broadcast on the speaker in real time

I will describe it as difficult, almost not possible. You need special audio boards to handle mics and speakers.

thanks for reply , I will do any thing to do that but how I do this with any price

The difficulty is that direct audio processing, or handling, needs high speed processors.
Such ones are available on boards to plug in to some Arduinos.
A Raspberry Pi is a high capacity device.

Wait a little for audio board helpers to step in.

Do you mean speech synthesis? Or just processing live audio?

Maybe it would help if you actually describe what you want to build...
Something like a walkie-talkie?
Robot / stuffed doll that can hold conversations with you?
Alexa / Echo clone?

It is but as it is a Linux device real time processing of speech is not as easy as using a controller.

So what is the Arduino going to do that connecting a mike to an amplifier and speaker will not?

MP3 recording and playback boards exist, for cheap.

Purchase a karaoke machine, it will be probably months quicker and a lot less money. It will not be real time but reasonably close I assume to your definition of real time. You need to define real time, currently it is a subjective measurement. Note as soon as there is processing there is delays, it could be picoseconds to forever depending on the hardware.
