Sorry if i do silly questions and my english is poor, but i need help to realize an interactive installation for my univeristy course, and this is first time that i use Processing...

I read some example, something interesting, but not clear enought to do that i want.

And that i want is:
when i speak in microphone, some text appear on screen.
If i speak with low voice, but if i speak a little more highter another text appear, and so on...

Which library is the best (and Easier)?
Do you know some example that i can see to understand better what i have to do?

Thank you!

Thanks for your answer, before i read your message, i try something with sonia:
----------------------------------------------------
import pitaru.sonia_v2_9.*;



void setup(){
 size(600,600);
 Sonia.start(this);
 LiveInput.start(256);
 }

void draw(){
 background(256,256,256);
 getMeterLevel();//mostra il volume
 }
 
void getMeterLevel(){
 float meterDataRight=LiveInput.getLevel();
 
 
 PFont fontA = loadFont("CourierNew36.vlw");
 textFont(fontA, 36);
 
 if(meterDataRight>=0.01&&meterDataRight<0.2){
   text("word",50,50);
   fill(0);
   }
 if(meterDataRight>=0.2&&meterDataRight<0.3){
   text("Hello",200,100);
   fill(0);
   }
 if(meterDataRight>=0.3&&meterDataRight<0.4){
   text("STRong",400,300);
   fill(0);
   }
 if(meterDataRight>=0.4){
   text("CRY!!!",150,500);
   fill(0);
   }
}

public void stop(){
 Sonia.stop();
 super.stop();
 }
------------------------------------------

but i don't know how i can do 2 things (i know that will be stupid... but this is my first code ):

1) how can i take on screen the word for more time? and make it disappear slowly?
2) how word can appear in random position on screen?

Thanks.
