We operate different types of analysis, linguistic and biometric, with the spectrographic study of the formants of the voices to be compared.
The formants are a graphic and scientific indication of the resonance that the sounds emitted by the individual have in the complex architecture of the vowel apparatus.
The formants are a real vocal imprint, which can have unique characteristics in physical morphology, and individual accent.
Biometric analysis is carried out with the aid of advanced techniques and very sophisticated software.
The result will be a likelihood ratio, usable in the legal field.
Listening is carried out in a soundproofed and treated environment, with professional monitor listening.
