So, I'm working on a project in which I am trying to integrate an AI conversation robot.  I'm pretty new to [all] this but I've got it set up now to where I can type a message, and it will post to an online chatbot and then print the response.  My problem is that I have to change the string, and then rerun the program whenever I want to send another message.

My goal is to make it so that I can edit the string while it is running with an outside voice recognition software (i.e. Windows speech recognition)which will just type whatever is said into any text field.  Then I think I will need to use something along the lines of "countdown" to automatically send the string once you pause for a certain amount of time after you have spoken your message.

Does anyone have any advice on how this might be accomplished?  Is there a way to have a little text field that you can just edit while the sketch is running?

Here is my chat sketch so far:

import processing.serial.*;
import cc.arduino.*;

Arduino arduino;

void draw()
{
   String send = "Hello.";  //message to be sent to chatbot
   
   try {
       // Construct data
   String botid = "botid=f5d922d97e345aa1" + "&" + "custid=22345678";
   botid += "&" + "input=" + send;
   
           // Send data
       URL url = new URL("http://www.pandorabots.com/pandora/talk-xml");
       URLConnection conn = url.openConnection();
       conn.setDoOutput(true);
       OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
       wr.write(botid);
       wr.flush();
   
       // Get the response
       BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
       String back;
       while ((back = rd.readLine()) != null) {
           
           int p1 = back.indexOf("<that>")+6;  //the response is in between "<that>" and "</that>"
           int p2 = back.indexOf("</that>");
           String response = back.substring(p1, p2);  //process line
           println(response);
           
           }
       wr.close();
       rd.close();
   } catch (Exception e) {
   }
   noLoop();
}


Thanks!

Great suggestion, thanks!  This controlP5 library is pretty awesome.  From a quick test, the Textfield allows input from external speech recognition software, so it is definitely a huge boost towards the end goal.  
Thanks again,
