HERRERA MARTINEZ, Marcelo; ALDANA BLANCO, Andrea Lorena  e  GUZMAN PALACIOS, Ana María. Speech pattern recognition for forensic acoustic purposes. Tecciencia [online]. 2014, vol.9, n.17, pp.37-44. ISSN 1909-3667.  https://doi.org/10.18180/tecciencia.2014.17.5.

The present paper describes the development of a software for analysis of acoustic voice parameters (APAVOIX), which can be used for forensic acoustic purposes, based on the speaker recognition and identification. This software enables to observe in a clear manner, the parameters which are sufficient and necessary when performing a comparison between two voice signals, the suspicious and the original one. These parameters are used according to the classic method, generally used by state entities when performing voice comparisons.
