The Author has been recently appointed by Naples Law Court to identify the voices of anonymous criminals present in telephone calls intercepted by the Police. The many technical problems faced on such occasions make this task very hard and its results probably questionable. The method followed is here tested by means of a simulation experiment: the same procedures are applied to a group of voices including a known voice (FAL) which is pretended to be the criminal's and three other voices (X, U, Z) among which is a sample of the same known voice. If the result is an identification of the right voice (X) as belonging to the speaker to identify (FAL), the method will prove to be reliable.
