DANSK DSF/ISO/IEC FDIS 19794-13 PDF

This part of ISO/IEC 19794 specifies a data interchange format that can be used for storing, recording, and transmitting digitized acoustic human voice data (speech) assumed to be from a single speaker recorded in a single session. This format is designed specifically to support a wide variety of Speaker Identification and Verification (SIV) applications, both text-dependant and text-independent, with minimal assumptions made regarding the voice data capture conditions or the collection environment. Other uses for the data encapsulated in this format, such as Automated Speech Recognition (ASR), may be possible, but will not be addressed here. This standard also does not address handling of data that has been processed to the feature or voice model levels. No application-specific requirements, equipment, or features are addressed in this standard. This standard supports the optional inclusion of non-standardized extended data. This standard allows both the original data captured and digitally-processed (enhanced) voice data to be exchanged. A description of any processing of the original source input shall be included in the metadata associated with the voice representations. This standard does not address data streaming. It is advisable that stored and transmitted biometric data be time-stamped and that cryptographic techniques be used to protect their authenticity, integrity and confidentiality; however such provisions are beyond the scope of this part of 19794. Information formatted in accordance with this part of ISO/IEC 19794 may be recorded on machine-readable media or may be transmitted by data communication between systems. A general content-oriented subclause describing the voice data interchange format is followed by a subclause addressing an XML schema definition. The standard includes vocabulary in common use by the speech and speaker recognition community, as well as terminology from other ISO standards.
