ABSTRACT

Forensic phoneticians often have to deal with suboptimal recordings. A lot of work has been done to find the identifying characteristics of speakersí voices. For this purpose, it is important to know the limits of the methods used. Media such as mobile phones or conventional tape recorders are often involved in forensic cases. This experiment aims at demonstrating the acoustic effects of channelling speech samples via such media. The results show that media such as micro cassettes and mobile phones are suboptimal from a forensic phonetic point of view.
