Prosuono, led by Marco Perino, specializes in speaker voice identification examinations and voice comparison analysis.

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 analysis, including:

• Phonetic-Linguistic Analysis (perceptual): We examine not only timbre, but also elements such as intensity, pitch, speech rate, inflection, cadence, and speech habits.

• Parametric Analysis: We analyze and compare the formant traits of the subjects under examination. Formants offer a graphical and scientific representation of the resonance of sounds produced by an individual, from the vocal cords to the lips — a kind of vocal fingerprint. While voice variability prevents it from being as uniquely codified as an actual fingerprint, 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 collected in penal institutions, courts, or similar facilities, we have professional recording equipment of various types available.

If a recording is not in optimal condition for use in legal proceedings, we offer restoration, cleaning, and noise removal services.

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

Every new client receives a free feasibility assessment after the initial contact.
