- Description
- 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. DSS 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. Modern phycoacoustical codecs that perform nearly as well at only slightly higher bitrates have led to this speech coding standard being less used in modern voice recording equipment.
- The Portable Voice Format (PVF) is a digital audio file format primarily used for storing voice recordings. PVF files are designed to encapsulate voice data at various bit rates, making them suitable for applications where voice clarity and file size are critical, such as voicemail systems, interactive voice response systems, and other telephony applications. Unlike more common audio formats that aim for high fidelity and music playback, PVF focuses on the efficient encoding of speech, optimizing for intelligibility and compact file size.
