How to use Google Translate TTS with the new V2 API?

I used to call Google Translate TTS to download an audio file using this url: http://translate.google.com/translate_tts?tl=en&q=Hello+world!

However Google changed the way that works and therefore I can no longer download the audio files. I've signed up for a free trial for Google Translate API V2, but can't find how to get the TTS audio files.

Any idea?
