We all know the world is progressing faster than ever before, and we are in the age of digitalization. While this has numerous advantages, there are drawbacks too. Digitalization has given birth to crimes that have no physical evidence. These crimes are often referred to as cybercrimes. Hacking, threatening and online abuse, scamming, and other similar sorts of activities all come under cybercrime.
Crimes like threatening or scamming someone on a phone call were previously very difficult to solve, but the new voice identification technology has helped tackle this problem recently.
In this blog, we’ll explain how voice identification technology helps solve cases.
Comparing the Voices
Voices contain details that are unique to each person due to biological and behavioral variances in how people talk. This makes it possible to distinguish people based on their voices.
Forensic analysts must examine how similar two voices are when comparing them and determine if they relate to a certain individual. If they aren’t identical, it’s possible that perhaps the suspect isn’t the criminal. They must also think about how different the two voices are.
Although the voice identification technology is very advanced, it’s still not 100% accurate. This is because the human voice is not like fingerprints or DNA, which are always the same. It’s something that can change for various reasons in a time period as short as an hour. One person can sound different at two different points in time.
Linguistic Analysis
A study of languages according to scientific methods is known as linguistics. It includes the formation, usage, and understanding of a particular language. For voice identification to work, voices are studied by linguistic experts. The features usually studied are:
Pitch:
How high or low the pitch of a person’s voice is. The changes in pitch are examined when a person says different words.
Voice Quality:
The overall voice of a person is also considered. For example, some people have a heavy voice, others have a squeaky or creaky voice, etc.
Rhythm and Timing:
How fast a person speaks, and their emphasis on the certain character of words.
Fluency:
How often does a speaker pause, get disrupted, or miss or skip words, either intentionally or non-intentionally.
