Digital Speech Standard (.dss) is a digital speech recording standard which was jointly developed and introduced by Olympus, Grundig and Phillips in 1994.
The first choice for professional speech applications
The introduction of .dss marked the establishment of a compatibility standard for digital audio files in speech format that drastically reduces both file size and transfer volume for speech recordings.

.dss reduces memory requirements and transfer times with minimal quality loss and low energy consumption to about 1/12 of normal consumption. This high audio quality for speech recording, along with the high compression rate, result in easy handling of audio files.

The .dss format has several practical advantages:
• Less memory requirement for archiving
• Audio files can be transferred by email at high speed
• Multiple dictations on one device
• Possible to save additional information directly to dictations e.g. time, date, dictation length, priority etc

For professional speech applications .dss is the first choice with regards to a standardised and future-proof storage format for speech files.
