Split string, add action to every word

There is a text. Which must be split into words and to create an action to every word, when pressed, plays a sound file, specified for this word.

How to do it automatically? Let's say I know how to split a string into words, and how to add action to every word?

I need to create gameObect according to each word and specify Rect according to a word position, then add script to interact with this Rect? But how to calculate each word position?

And maybe there are another solution?

I add a little more explanation:

I dont know how to do 1) and 2).

 public class Texttext : MonoBehaviour {
     public GUIText guiText;
     public ActionOnClick actionScript;
     // Use this for initialization
     void Start () {
         guiText.text = "Text, text text!\nText? Text!\nText, text text, text...";
         string[] split = guiText.text.Split(new char[] { ' ', ',', '.', ':', '\t', '\n'});
         foreach (string str in split)
             if (str != "")
             {
                 Debug.Log(str);
                 // Create GameObject
                 GameObject go = new GameObject(str);
 
                 // 1) Calculate word position (!!!)
                 Vector3 wordPosition = new Vector3(0, 0, 0);
 
                 // 2) Create Rect according this position (!!!)
                 Rect wordRect = new Rect(wordPosition.x, wordPosition.y, wordWidth,wordHeight);
 
                 // Add action to this gameObject
                 go.AddComponent<ActionOnClick>();
                 go.GetComponent<ActionOnClick>().wordPosition = wordPosition;
                 go.GetComponent<ActionOnClick>().wordRect = wordRect;
             }
     }
     
     // Update is called once per frame
     void Update () {
     
     }
 }

The problem is to automate this: Write text -> Calculate -> Click on Word get a Sound.

And that's what I want to get:
