Q:

How do I get Hebrew voice input and output with wit.ai on Android

Wit.ai supports Hebrew as seen here. I suppose that means Hebrew text.
But how do I get it to understand my speech and to output in Talkback (the equivalent to IOS Voiceover) on Android. Do I have to install some external Hebrew speech reco or text-to-speech like Dragon, like they claimed in the past on Negishut (Hebrew accessibility website)?  
Or does the Google Speech already understand my Hebrew speech and can translate it into Hebrew text? And does the Talkback already support Hebrew? 
Is there anything else I need to do to get this working on an advanced version of Android and smartphone (say Samsung Galaxy S)? 

A:

Download and install
https://play.google.com/store/apps/details?id=es.codefactory.vocalizertts
After installing the application, you must purchase the preferred voice - for this matter Hebrew.
Next you need to go to the "Text to Speech" settings and choose Vocalizer as a speech engine
