What does the term voice print refer to? Is it similar to footprints?
Voice print can refer to the spectrogram of a voice. More specific uses include: ... The stored template used to identify a person via their voice in speaker recognition.
A voiceprint is a set of measurable characteristics of a human voice that uniquely identifies an individual. ... The term applies to a vocal sample recorded for that purpose, the derived mathematical formula, and its graphical representation. Voiceprints are used in voice ID systems for user authentication.
Footprints are the impressions or images left behind by a person walking or running. Hoofprints and pawprints are those left by animals with hooves or paws rather than feet, while "shoeprints" is the specific term for prints made by shoes. They may either be indentations in the ground or something placed onto the surface that was stuck to the bottom of the foot. A "trackway" is set of footprints in soft earth left by a life-form; animal tracks are the footprints, hoofprints, or pawprints of an animal.

Footprints can be followed when tracking during a hunt or can provide evidence of activities. Some footprints remain unexplained, with several famous stories from mythology and legend. Others have provided evidence of prehistoric life and behaviours.
Previously, ink used in jet printers did not exceed 10 to 100 times the viscosity of water, so the researchers designed a system called Acoustophoretic Printing, in which sound waves exceeded 100 times the force of gravity, Such as white honey and viscous polymers that exceed the viscosity of water 25,000 times. The viscosity of these liquids varies greatly with temperature and composition, making it difficult to improve printing parameters to control droplet sizes. Daniel explained to the "science" that the sound waves will increase the pressure and allow droplets drop from the mouth of the printer in a small size, and fell Newton's apple from the top of the tree thanks to gravity, as described. Thanks to this new technique, scientists have been able to use white honey and biological polymers such as polyethylene glycol (PEG) and liquid minerals such as mercury, as well as fluids containing body tissues and cells as printer inks, to make micro capsules that can be used as drug transporters. Capsules were previously made in large volumes, because fluid viscosity was a barrier to droplets from printer nozzles designed to drive only light fluids, which would not otherwise be able to handle heavy viscous liquids. The slower the precipitation, . "It's a new innovation of its kind," said David Collin, a researcher at the Massachusetts Institute of Technology in Cambridge, commenting on the results of the study for Science. He stressed that the technology of drip irrigation is very important for future generations, pointing out that Daniel and his colleagues were able to use any liquid viscosity regardless of the degree of his wife, and he concluded that the researchers controlled the volume of liquid droplets using sound waves, by pushing strongly from the nozzle of the printer. He stressed that this technology will have a significant impact on the research community, and that there is an industrial and commercial revolution will result from their application, he said. "Our main goal is to handle any liquid, regardless of its wife and composition, by designing a system that allows printing using any type of liquid ink," Daniel concluded.
Print-through is a category of noise caused by contact transfer of signal patterns from one layer of tape to another.
Voice print is an electronic translation of sound into a pictorial or graphical representation; essentially, it is a sonogram of a person's voice. Voiceprints are compare with footprints in their unique representation of identity. Voice print is safer than footprint.
Voiceprint is a biometric. Voiceprint is so unique for each person, it is becoming the main security feature for customer identification for businesses and banks. This technology can help authenticate customer identity with voice alone. It’s more secure than passwords.
Voice prints are some of the key factors in speech analysis which include individually distinctive patterns of speakers' voice characteristics pictorially produced. In point of fact, it is the acoustic analysis of speech in terms of frequency, duration, and amplitude. In forensic linguistics, which deals with a wide range of criminal cases such as murder, rape, drug dealing, bomb threats and terrorism, experts compare recorded speech samples by producing respective spectrograms for the sake of identifying the voice of the targeted victims.
