Respiratory Sounds as an Idiosyncratic Feature in Speaker Recognition

Miriam Kienast, Florian Glitza

Landeskriminalamt Berlin, Germany

This is a preliminary report on a study in which speaker-specific features of non pathological respiratory sounds were examined in regard to forensic issues. This study is based on the assumption that sounds which are created by in- or exhalation may contain speaker-specific information but that they were rarely examined in relation to forensic speaker recognition.
   The database of this study consists of speech samples (spontaneous speech) of 10 male German speakers. In detail the number, kind, duration and spectral characteristics of respiratory sounds were examined in regard to between- vs. within-speaker variations. Another aim was to analyse measurement techniques facilitating examination in the case of telephone transmission.
