+ Speaker recognition protocol on the Voxforge Database
+=======================================================
+
+`Voxforge`_ offers a collection transcribed speech for use with **Free** and **Open Source Speech Recognition Engines**.
 In this package, we design a speaker recognition protocol that uses a **small subset of the english audio files** (only 6561 files) belonging to **30 speakers** randomly selected.
 This subset is split into three equivalent parts: Training (10 speakers), Development (10 speakers) and Test (10 speakers) sets.

 This package serves as a toy example of speaker recognition database while testing `xbob.spkrec`_.
 
 The `xbob.spkrec`_  is developed at Idiap during its participation to the `NIST SRE 2012 evaluation`_. If you use this package and/or its results, please cite the following
