A print produced by a sound spectograph
showing frequency and intensity changes in
the human voice when visually recorded. It
enables individual speech characteristics to
be determined. First used as evidence in
criminal trials in the USA in 1966,
voiceprints were banned in 1974 by the US
Court of Appeal as `not yet sufficiently
accepted by scientists'.
