Voice comparison, or speaker recognition, is the process that compares a known voice sample to an unknown voice sample. This comparison determines if the speakers are the same or if they are different. A forensic voice comparison investigation requires critical listening, frequency/waveform analysis, exemplar sample and voice biometric testing. These ensure that the investigation has an accurate outcome.

voice identification

The human voice has key characteristics that are determined by physical aspects of the vocal tract. Each person is different, these characteristics can create a set of data for each voice to be used in the comparison. Primeau Forensics utilizes numerous speech analysis software so that tests and data points can be checked for accuracy.
