Digitally Disguised Voices

Document Thumbnail

One of the newer challenges in audio forensics is the investigation of voice recordings that are suspect of being manipulated by utilizing digital signal processing. This paper presents a number of voice manipulating tools available. Several tools are developed for musical purposes. However, they are eventually applied to talkers’ voices as well. This implies both post-processing real time processing. The voice alterations are demonstrated and the influence on acoustic parameters normally examined in connection with forensic voice analysis and authentication are presented. This includes the effect of pitch shifting, pitch modeling, formant relocation, removal of voiced sounds, and its’ influence on background sounds (ENF).
