Download a file from a site (partly written in Javascript) using Python

I'm trying to use Python to download a voice file (mp3) from this site:

I've tried to use mechanize and twill but I haven't got the proper result. I've heard about selenium as well. Anyway, I don't even know if it makes sense technically (mechanize + Javascript).

I was looking for an answer and finally I've found this solution.

It seems like a similar problem to mine but I have absoutely no idea what should I put instead of the 4th line.

If you have any proposition (maybe completely different to mine) I'll be glad to see it.

(Moving to answer to get more space)

Thanks for pointing me to selenium, I didn't know that and it looks cool; anyways: I had a quick look and the js seems to fire an ajax request, that yields no apparent result -- I guess the audio transfer is done some way in the background via flash or so; anyways: what about using the service they offer: developer.ivona.com instead of trying hacking your webservice out of the demo interface..?

Anyways, here it is the hacked web-service you asked for:

This is the URL you want to GET:

"http://www.ivona.com/voicetest.php?rtr=1&t2r=%(the_text)s..&v2r=dXNfc2FsbGk.&lang=us" % dict(
    the_text=base64.b64encode("Hello, world!"),
    the_voice=base64.b64encode("us_salli"),
    )

You can test that with, for example, mplayer:

mplayer "http://www.ivona.com/voicetest.php?rtr=1&t2r=SGVsbG8sIHdvcmxkIQ==..&v2r=dXNfc2FsbGk.&lang=us"

And, from Python, use urllib to retrieve and store somewhere.

Beware that, since this is an unauthorized use, you might get blocked / incur in legal issues / etc. -- don't use in a production application!
