Spectrographic Analysis of Vocal Alterations

To what degree can an individual’s formant production change when their vocalizations are altered? If the spectrographic signature of a person’s voice is the result of unique nuances in their physical build, can this vocal “fingerprint” be altered by subtle manipulation? To answer these questions, this paper presents comparisons in data gathered from various individual's speech. Looking at vocalizations in this detail yields insightful information on how a person’s voiceprint can be affected when certain factors are involved. More specifically, either when an individual is experiencing obstructed nasal airflow due to allergies or sickness or when they are mimicking another person.
