Text to Speech plugins?

Well this isn't for android but for iOS you can use http://u3dxt.com ;)

That is interesting especially considering the realtively low price and the additional tools included, however at the moment I'm more interested in Android development, and I'm still looking for a plugin for that. I have a project that is almost completed, and I'm testing it with this: http://forum.unity3d.com/threads/56038-Text-to-Speech-Dll-for-Win32 but of course this is only for windows, so I'm still looking.

 using UnityEngine;
 using System.Collections;
 using System.Text.RegularExpressions;

 public class GoogleTextToSpeech : MonoBehaviour
 {
         public string words = "Hello";
     
         IEnumerator Start ()
         {
                 // Remove the "spaces" in excess
                 Regex rgx = new Regex ("\\s+");
                 // Replace the "spaces" with "% 20" for the link Can be interpreted
                 string result = rgx.Replace (words, "%20");
                 string url = "http://translate.google.com/translate_tts?tl=en&q=" + result;
                 WWW www = new WWW (url);
                 yield return www;
                 audio.clip = www.GetAudioClip (false, false, AudioType.MPEG);
                 audio.Play ();
         }
     
         void OnGUI ()
         {
                 words = GUI.TextField (new Rect (Screen.width / 2 - 200 / 2, 10, 200, 30), words);
                 if (GUI.Button (new Rect (Screen.width / 2 - 150 / 2, 40, 150, 50), "Speak")) {
                         StartCoroutine (Start ());
                 }
         }
 
 
 }//closes the class
 

Check this asset: http://forum.unity3d.com/threads/released-android-tts-plugin.270789/

It's only 2$ and there is an APK you can download and test on your device first to check if it really works and what it can do. The scene is included in the asset.

I tried using Jefferson's Google approach in Unity 5.0.1. and noticed two things that might be helpful to know:

1) Google has put in a redirect to a CAPTCHA in order to prevent requests by 'robots'. Thus, it seems, the request from script yields no results. Unless I've missed something else.

2) audio is now deprecated and Unity suggests to use GetComponent<AudioSource>() instead.
