Abstract
Audio tapes are often used as evidence in courtrooms. This report is about a case of threatening telephone calls. Tape authentication was done by visual and statistical analysis of pitch and loudness contours. Voice identification was done by means of a “voice line-up”, i.e. judging differences and similarities in a series of matched voices (including the defendants’ voice) and the voice on the exhibit recording. Methods for authentication and identification are described in detail.
