Funzione utilizzata per costruire il modello di riconoscimento audio
a partire da un insieme di istanze che vengono fornite dall'utente
attraverso l'apposita GUI.
In particolar ela funzione consente di :
- ottenere la lista di istanze specificate dall'utente
- recuperare il path completo associato a ciascuna istanza
- unire le istanze in un unico file audio
- effettuare la costruzione del modello di riconoscimento vocale
- creare la persona e il modello sul database
- associare i file creati alla persona e al modello
- rimuovere tutti i file temporanei creati
