Prosuono Studio, led by Marco Perino, specializes in Speaker Voice Identification Examinations and Voice Comparison Analyses.
The Voice Comparison Examination involves comparing a known voice from private recordings or wiretaps with a reference voice, usually belonging to a suspect or defendant.
To reach our conclusions, we perform several types of analyses, including:
-
Phonetic-Linguistic Analysis (perceptual type): We analyze not only the timbre but also elements such as intensity, pitch, speech rate, inflections, cadences, and speech habits.
-
Parametric Analysis: We analyze and compare the formant traits of the subjects under examination. Formants provide a graphical and scientific indication of the resonance of sounds produced by the individual, from the vocal cords to the lips—a sort of vocal fingerprint. Although voice variability prevents it from being as uniquely codified as fingerprints, it can still exhibit distinctive characteristics.

Graphical and Visual Representation of the vocal patterns of the voices under examination.
-
Parametric Statistical Testing.
If phonetic samples need to be acquired in penal institutions, courts, or similar facilities, we have professional recorders of various types available.
If the audio is not in optimal condition for use in legal proceedings, we provide restoration, cleaning, and noise removal services.

Forensic audio evidence can originate from criminal investigations conducted by law enforcement or as part of an official inquiry into cases of workplace harassment, accidents, fraud, defamation, or other civil incidents.
