ISO/IEC 19794-13:2018规定了一种数据交换格式，可用于存储、记录和传输假定来自单个会话中记录的单个扬声器的数字化人声数据（语音）。该格式专门设计用于支持各种各样的说话人识别和验证（SIV）应用程序，包括文本相关和文本无关的应用程序，只需对语音数据捕获条件或采集环境进行最低限度的假设。以这种格式封装的数据的其他用途，如自动语音识别（ASR），可能是可能的，但本文档中未涉及。本文档也不涉及已处理到功能或语音模型级别的数据的处理。 本文件中未提及具体应用要求、设备或功能。本文档支持可选地包含非标准化扩展数据。本文档允许交换捕获的原始数据和经过数字处理（增强）的语音数据。原始源输入的任何处理的描述将包含在与语音表示（VRs）相关的元数据中。本文档不涉及数据流。 存储和传输的生物识别数据带有时间戳，以及使用加密技术保护其真实性、完整性和机密性的规定不在本文件的范围内。 根据本文件格式化的信息可以记录在机器上- 可读介质或可通过系统间的数据通信进行传输。 描述语音数据交换格式的面向内容的通用子类后面是一个子类，用于处理XML模式定义。 ISO/IEC 19794-13:2018包括语音和说话人识别界常用的词汇，以及其他ISO标准中的术语。

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.
