Digital Speech Standard (DSS) is a
proprietary compressed digital
audio file format defined by the International Voice Association, a co-operative venture by
Olympus,
Philips and
Grundig. It was originally developed in 1994 by Grundig with the University of Nuremberg. In 1997, the digital speech standard was released, which was based on the previous
codec. It is commonly used on
digital dictation recorders.
