Abstract

Speech science has a storied and illustrious past. Many studies are conducted for research on speech and voice acoustics, which focuses on speech. Te human voice
is our most basic and self contained instrument. When it comes to voice processing,
the source flter paradigm may be used. It’s common to think of the voice as having
two distinct processes: one that produces the initial tone and another that produces
the fnal tone. Tis is done in order to create a speaker’s identity by providing an accurate phonetic profle of that individual. Other related felds include improving low
quality audio fles and verifying disputed recordings to see whether they have been
manipulated, edited, or otherwise tampered with. In contrast, a digital recording samples the transduced waveform and transforms each sample into a binary number code
similar to that used by computers. Speech analysis was also used in the investigation
of recordings allegedly made by Osama bin Laden, the world’s most wanted terrorist.
Tis research will discuss if voice changer apps can be used to mask one’s voice. Tere
have been several instances where the perpetrator has used these apps to alter their
speech. Tis research looks at how the characteristics of any voice can be altered or
not by the use of these apps, how they function, and how they affect voice recognition.
Tis paper also examines whether these apps really assist the perpetrator in eluding
voice recognition experts.
