Voice Comparison

For the Voice Comparison service, we mean the Comparison of a known voice from Private Recordings or Wiretapping, with a comparison voice, usually belonging to a suspect or accused person.

Audio Forensic evidence may come from a criminal investigation conducted by the Police or as part of an official investigation into an accident, fraud, accusation of slander or any other civil incident.

We perform different types of analysis for our conclusions, including:

  • Subjective Analysis, where we analyze not only the Timbre but also elements such as Speech Speed, Inflections, Cadences, Intensity.

  • Parametric Analysis, where we analyze and compare the Formant traits of the subjects being compared.

The Formants are a graphic and scientific indication of the resonance that the sounds emitted by the individual have in the complex architecture that goes from the vocal cords to the lips.

The Formants are a real vocal imprint that although, due to the very variability of the nature of the voice, it does not have the same univocal codification typical for example of fingerprints, it can have unique characteristics.

Biometric analysis is carried out with the help of advanced techniques and very sophisticated software.

The result will be a likelihood ratio.

Prosuono studio is specialized in Audio Forensics.

Our more than twenty years of experience is also available for advice on plagiarism, and for Digital Audio Workstation software assistance.

    I did a Logic Pro X course with Marco via skype and I can only speak well of it. He is knowledgeable, professional, helpful and patient. His explanations are clear and he is always ready to answer any doubts or questions. I highly recommend it to anyone who wants to delve into or deepen the use of Logic for music production.
