I have a co-worker of mine who used Google Tradutor himself.

See how he did it in PHP:

$google_url = 'https://translate.google.com.br/translate_tts?ie=UTF-8&q=%se&tl=pt&total=1&idx=0&textlen=5&tk=489936&client=t&prev=input&ttsspeed=0.24';

$text = urlencode('Meu nome é Wallace');

$url = sprintf($google_url, $text);

copy($url, 'meu_arquivo.mp3');

This code can be used in any other language (as long as it supports copying remote files).

Update 06/01/2016

I just discovered that this information is now restricted, and that you can only use this feature through a Translation API .

It also seems like pay for the service .

I found it!

link Very interesting indeed!
