several test on my free time!
Fix clases :
ValidatingPropertySheet
PropertyType

In order to enable capacity of read properties as file:
Old:
voce.SpeechInterface.init("../../../lib", false, true,  "./grammar", "digits");

New:
		String voicePath = RecognitionTest.class.getResource("/org/jrichardsz/poc/voce/resources").getPath();
		String grammarPath = RecognitionTest.class.getResource("/org/jrichardsz/poc/voce/resources/gram").getPath();

		voce.SpeechInterface.init(voicePath, false, true,grammarPath, "digits");
