ROSAS, Claudia  e  SOMMERHOFF, Jorge. Idiophonic variability in Spanish as a forensic tool. Estud. filol. [online]. 2006, n.41, pp. 235-249. ISSN 0071-1713.  doi: 10.4067/S0071-17132006000100014.

In this paper we present some methodological aspects and preliminary results of an investigation in progress dealing with a section of the experimental corpus obtained from sentences read by three valdivian informants in both an echoless and an reverberant environment. The reverberant field modified the characteristics of the voice analyzed. In accordance with the acoustic selected indicators the main differences were in the history of the compared formants: F1, F2, F3 and F4 with some variations in frequency, intensity and length in the spectral zone. The smallest difference was observed in the F0 rang
