Voice print identification is an process used to compare a known voice to an unknown voice. Voice prints allow the forensic expert to determine the characteristics of the frequencies present in a persons voice through visual inspection. A voice print displays frequencies prominent in the voice measured.
The process of voice print identification includes reviewing the frequencies displayed in a known speaker voice print and comparing them to an unknown speaker voice print. This process was developed to better understand if a known persons voice matches the unknown persons voice.
A sonogram is a frequency measurement tool that can be used to create a voice print. Several years ago, voice print analysis evolved into voice identification. Voice identification uses a voice print identification and was complimented with crital listening and electronic measurement. Many software programs are available today for voice identification that accomidate all three processes.
Everyone has very distinct features to their voices, regardless of how slight or severe they might be. Physical characteristics that contribute to speech is the mouth, teeth, larnyx, vocal chords and throat to name a few.
When compiling information for a voice identification the forensic expert must critically listen over and over to the unknown voice taking scrupulous notes of all speech characteristics. This is called the critical listening phase. Experts focus on characteristics such as inflection, pronunciation of certain words, any form of an accent, stutters, and lisps, amongst other variables.
Think about a voice you know and are familiar with like afellow employee. You can have your back to the door and when they walk in and say hello, you know who they are without looking. This is the type of familiarity that has to be achieved during voice identification testing of the unknown voice as well as the known voice.
Experts also review the visual appearance of a voice which is the purpose of a voice print. They also measure the electric signals of each frequency present in a voice using spectrum measurement tools.

The blood vessels in the retina are unique to each person, as is their DNA. Aside from fingerprints the palm also has a unique print. Voice print identification is another way to identify a person and although a voice can be faked it will never be exactly the same. And lastly I guess would be handwriting.

Can a nose print of a cow be used to determine identity?
Yes, nose printing of a cow can be used to determine identity. A cows nose print is just like a human finger print. This type of identification is effective because a cow's nose will never change and that makes nose printing unlike other forms of identification.

What are some common biometric identification techniques?
Common biometric identification techniques include: fingerprint scanning handprint scanning hand geometry facial recognition iris scanning retina scanning voice print keystroke anaylysis/typing rhythm note that fingerprint, handprint, and hand geometry may be combined with thermal and pulse scans to combat some methods used to defeat those types of biometric scanners
What happens after the pattern of an individual print has been matched?
After the pattern of an individual print has been matched, it can be used for identification purposes, such as in forensic investigations or security access systems. The matched print can then be compared against other prints in a database to determine a potential match or identity of the individual.
What are the navy uniform regulations on wearing security identification badges?
I don't know a lot about that but I do know which tool you need to print your security identification badges : a card printer. If you need information, you should check out Evolis card printers, it's a company based in France, they offer a wide range to answer identification issues.
