The invention discloses a digital voice print
identification system. The
system comprises a plurality of collectors; a voice
print processor which is connected with a plurality of collectors; a voice print
database which is connected with the voice
print processor; and a comparing and adjusting engine which is connected with the voice print
database. The invention further provides a validation method of forensic identity, and the method comprise the following steps: performing voice print
processing on live recording to obtain a first voice print characteristic; obtaining second voice print data; computing the data to obtain a validation model
library; comparing and storing a first difference in the voice print
database; and determining the similarity of the first difference and a second difference. The invention further provides an identification method of the forensic identity. The method comprises the following steps:
processing the data to obtain a third voice print data; compiling an identification model
library according the identity information in the live recording; comparing the sampled voice print characteristic of a suspect with the identification model
library and recording the first difference; comparing the third voice print difference with the identification model library to obtain the second difference; and performing similarity ordering on the first difference and the second difference to output an identification result.
