The purpose of this standard is to ensure that the dictation files recorded by products from industry leaders are compatible to play back. This ensures a larger market, giving the end user greater flexibility and choice, as well as the security of a controlled standard.

This Digital Speech Standard answers the need for high-quality, professional dictation and speech solutions for the modern digital information society. Offering outstanding audio quality for recorded voice, .dss files allow a high compression rate, reduced file size, network traffic and required storage capacity. The format also allows additional information, such as client/patient name and document type to be stored in the file header, further facilitating file organisation.

The DSS Pro (.ds2) format is a further development to the .dss format that supports better sound quality to get a more accurate speech recognition result and file encryption (128-/256-bit AES)to protect confidential dictation data. Special compression technology continues to facilitate recording in the form of small files, which is essential for sending dictations via email when on the move or transferring data over networks, as well as archiving.

For professional speech applications, .dss and .ds2 are the first choice with regards to a standardised and future-proof storage format for speech files.
