Voiceprint: A Comprehensive Guide to Its Legal Definition and Applications

Definition & Meaning

A voiceprint is a visual representation of a person's voice, created through a process called spectrographic analysis. This method captures the unique characteristics of a voice, including time, frequency, and intensity, and displays them as a series of lines or bars on a graph. The resulting image, known as a spectrogram, helps in identifying the speaker by comparing their voiceprint to that of another individual. Voiceprints are particularly useful in legal contexts where speaker identification is necessary.
