My b2evolution Version: 3.3.3

vozme is a web service in spanish that can listen to your text but within the site, useful for blogs and listen to texts such TextAloud.

how I can integrate the script http://vozme.com in b2evolution?

I tested with several of the codes that are there but I never worked

<div id="quijote">
En un lugar de la Mancha, de cuyo nombre no quiero acordarme, no ha mucho tiempo que vivía un hidalgo de los de lanza en astillero, adarga antigua, rocín flaco y galgo corredor.

</div>

<script type="text/javascript" src="http://vozme.com/get_text.js"></script>
<a href="javascript:void(0);" 
onclick="get_id('quijote','es','ml');">
Escucha este texto</a>

try and put this code inside the php code that displays the text of the article within the template.

<div id="articulo">
			<?php
				// ---------------------- POST CONTENT INCLUDED HERE ----------------------
				skin_include( '_item_content.inc.php', array(
						'image_size'	=>	'fit-400x320',
					) );
				// Note: You can customize the default item feedback by copying the generic
				// /skins/_item_feedback.inc.php file into the current skin folder.
				// -------------------------- END OF POST CONTENT -------------------------
			?>
</div>

<script type="text/javascript" src="http://vozme.com/get_text.js"></script>
<a href="javascript:void(0);" 
onclick="get_id('aericulo','es','ml');">

There is no way to integrate a script vozme.com?
