Speaker recongition is differentiaed from speaker identification: the former refers analysis of speaker identification. Aural-perceptual analysis- involves testing the effectiveness of human listeners in identifying a speaker through auditory procedures, such as a voice lineup. Forensic acoustic phonetics pertains to computerized/machine anlyses of selcted voice samples for the frequency and intensity of speech sound waves and resonance. Neither the arual-perceptual apparoch nor the acoustic apparch can uniquely charactierise a persons voice. Speakers cannot be identified with certainity from either audiotry or acoustic procedures. Arural-perceptual speaker identifications are difficult and eror prone. However, some witnesses are signficantly suprior to others in their accuracy of speaker identification for both familiar and unfamiliar speakers.
