Role of Second Formant Frequency( F2) in Forensic Speaker Identification

Abstract

Identification of a speaker specific feature is an almost impossible task because of the enormous number of features which can affect a single voice utterance.F2, (marker of vowel position) plays an important role in vowel identification. The present study is an statistical analysis conducted on the 16 speakers’ F2, F2- F1 and F3-F2 values for the vowels; “/a:/, /i:/ and /u:/. Vowel /a/ showed considerable height difference in Known sample (where the researcher knew the Speaker) and Unknown sample (someone else collected the sample).
