VOICE COMPARISON AND SPEAKER RECOGNITION
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.
Audio forensic expert, Edward Primeau, has been practicing audio forensics for over 37 years. He has specific training in voice comparison and speaker recognition and has extensive experience testifying in court. And as an audio forensic expert, Edward has testified in many cases in the United States and worked on cases in India, Turkey and France.
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.
