NBN ISO/IEC 19794-13:2021

This document 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-dependent 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 are not addressed in this documnet. This document 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 document. This document supports the optional inclusion
of non-standardized extended data. This document 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 is intended to be included in the metadata associated with the voice representations (VRs). This
document does not address data streaming.
Provisions that stored and transmitted biometric data be time-stamped and that cryptographic
techniques be used to protect their authenticity, integrity and confidentiality are out of the scope of this
document.
Information formatted in accordance with this document can be recorded on machine-readable media
or can 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.
This document includes vocabulary in common use by the speech and speaker recognition community,
as well as terminology from other ISO standards.
