ISO/IEC 19794-13:2018 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. ISO/IEC 19794-13:2018 includes vocabulary in common use by the speech and speaker recognition community, as well as terminology from other ISO standards.
Abstract
Overview
ISO/IEC 19794-13:2018 defines a standardized biometric voice data interchange format for storing, recording and transmitting digitized human voice (speech) assumed to come from a single speaker in a single session. The format is purpose-built to support a wide range of Speaker Identification and Verification (SIV) applications (both text-dependent and text-independent). It permits exchange of original and digitally processed (enhanced) voice recordings and includes an XML schema for metadata and structural description. Streaming, feature/model-level representations, and cryptographic/time-stamping requirements are intentionally out of scope.
Key topics and technical requirements
- Single-speaker, single-session assumption: Records are attributed to one individual and one capture session.
- Support for SIV use cases: Designed to work with text-dependent and text-independent speaker recognition workflows.
- Voice representation (VR) structure: Standard defines voice record headers and voice representation headers covering date/time, audio content descriptors, quality metrics and signal enhancement metadata.
- Audio content and encoding: The standard accommodates a variety of audio encodings and allows descriptive metadata for capture device, transducer and channel conditions.
- Metadata and processing traceability: Any processing applied to the original audio (e.g., enhancement) should be documented in associated metadata.
- Optional extended vendor data: Vendors can include non‑standardized extended data to support proprietary needs while preserving interoperability.
- XML schema and content-orientation: The document supplies an XML schema to represent records and associated fields for interchange.
- Conformance testing guidance: Annexes describe testing methodology for conformance to the format.
- Explicit exclusions: Does not address streaming, handling of feature or model-level biometric data, application-specific equipment, or security (cryptographic protection, time-stamping).
Applications and who uses it
ISO/IEC 19794-13:2018 is used by:
- Biometrics vendors and system integrators implementing speaker enrollment, verification and identification systems.
- Governments and border/security agencies managing voice biometric databases and identity programs.
- Telecom and call-center vendors implementing voice-based authentication (IVR-integrated SIV).
- Forensic labs and research organizations exchanging high-quality voice recordings with consistent metadata for analysis.
- Developers building interoperable voice data exchange pipelines between capture devices, storage systems and recognition engines.
Practical benefits include consistent record structure, improved interoperability between capture and recognition systems, and clear metadata for quality assessment and auditability.
