Forensic Voice Analysis

In today’s time, recording & interpreting a voiceprint in terms of the frequencies and intensities of the sounds made by an individual while speaking is vital, mainly for criminal investigations and military intelligence purposes. Every individual’s voice is distinct because the structure or composition of the vocal cords, vocal cavity, oral and nasal openings are specific to each.

What’s Voice Forensics?

Forensic Voice Analysis is the science of evaluating, filtering, and validating audio recordings for the objective of a hearing or trial. In addition, to investigate more on the above-mentioned, one needs to obtain an effective and efficient voice biometrics program. An approach which evaluates audio evidence precisely by applying voice biometrics technology in a way that makes it convenient to work with the obtained audio evidence. This would further help forensics experts as well as security-based companies to finalize voice treatment and speaker identification practices accurately.

How does it provide an advantage to investigation agencies?

Audio forensics tools utilize voice biometrics technology to examine voice and help forensics experts towards their crime prevention and investigation efforts.

By utilizing these tools, forensics experts would be able to:

• Ascertain whether a voice belongs to a specific individual
• Run a trial to check if a recording has been edited or altered
• Make a comparison of a target speaker with a database of potential candidates
• Precisely match a person’s identity with the audio evidence content
• Verify a person’s identity with an audio recording

Significance of Vocal Profile Analysis (VPA) from Sunartek
