Forensic voice comparison, or speaker recognition, is the process that compares a known voice sample to an unknown voice sample. This type of investigation determines the likelihood of whether the speakers are the same or different. A forensic voice comparison investigation requires critical listening, frequency/waveform analysis, exemplar sample, and voice biometric testing. All reports are peer reviewed, in order to confirm the results of forensic voice analysis accuracy.
Audio forensic expert, Edward Primeau, has been practicing audio forensics for over 37 years. In fact, he has specific training in voice comparison and speaker recognition and has extensive experience testifying in court. For example, Edward has testified in many cases in the United States and provided investigations internationally on legal cases in India, Turkey, and France
SPEECH RECOGNITION AND ANALYSIS
The human voice has key physical characteristics that determine the human vocal tract measurements called formants. First, each person’s voice is digitally unique, these characteristics can create a set of data for each voice used by an expert in the comparison. Second, each person’s voice is audibly unique to the human ear. As a result, Primeau Forensics utilizes numerous speech analysis tools to ensure the accuracy of the analyzed data points.
We understand the importance of forensic voice analysis accuracy when providing reports for litigation use. For example, our forensic voice comparison investigations are based best practices set forth by the scientific community. In other words, the methodology is based in an objective science, and therefore is repeatable. Moreover, the results are accurate and reproducible to ensure the integrity of the investigation. In addition, we understand the weight that our conclusions may have in a litigation and therefore give the utmost attention to detail for every investigation.
