Adding A.I Feature for Recordings module

I think the version has been published on stable.
I will try to work in it soon.

Oups I missed this question.Sorry.
The code get all voices available on the list.

/**
 * Get available voices list.
 * @return array Voices list
 */
public function getAvailableVoices() {
 .../...

So when a new voice is availble, it should be there on the list.

system default language is good. Because, sometimes you can work on the GUI in English with another language used by Asterisk.in German for example.

Well. After reviewing code. Everithing is already done to select the language bye default (global language). So, nothing to do here.
