This specification defines the media types of the Voice Extensible Markup Language (VoiceXML), the Speech Synthesis Markup Language (SSML), the Speech Recognition Grammar Specification (SRGS), the Call Control XML (CCXML), and the Pronunciation Lexicon Specification (PLS), the specifications of the W3C Speech Interface Framework.
本规范定义了语音可扩展标记语言（VoiceXML）、语音合成标记语言（SSML）、语音识别语法规范（SRGS）、呼叫控制XML（CCXML）和语音词典规范（PLS）的媒体类型，即W3C语音接口框架的规范。
VoiceXML ([VoiceXML2.0]) is an Extensible Markup Language (XML) designed for creating audio dialogs that feature synthesized speech, digitized audio, recognition of spoken and DTMF key input, recording of spoken input, telephony, and mixed initiative conversations. The associated media type defined in this document is "application/voicexml+xml".
VoiceXML（[VoiceXML2.0]）是一种可扩展标记语言（XML），设计用于创建音频对话框，其中包括合成语音、数字化音频、语音和DTMF键输入识别、语音输入录制、电话和混合主动对话。本文档中定义的相关媒体类型为“application/voicexml+xml”。
The Speech Synthesis Markup Language specification (SSML) defines an XML-based markup language for assisting the generation of synthetic speech in Web and other applications. The essential role of SSML is to provide authors of synthesizable content a standard way to control aspects of speech such as pronunciation, volume, pitch, and rate, across different synthesis-capable platforms. The associated media type defined in this document is "application/ssml+xml".
语音合成标记语言规范（SSML）定义了一种基于XML的标记语言，用于帮助在Web和其他应用程序中生成合成语音。SSML的基本作用是为可合成内容的作者提供一种标准方法，以跨不同的合成平台控制语音的各个方面，如发音、音量、音调和速率。本文档中定义的相关媒体类型为“应用程序/ssml+xml”。
The Speech Recognition Grammar Specification (SRGS) defines syntax for representing grammars for use in speech recognition so that developers can specify the words and patterns of words to be listened for by a speech recognizer. The syntax of the grammar format exists in two forms, an Augmented BNF (ABNF) Form and an XML Form. The respective media types defined in this document are "application/srgs" and "application/srgs+xml".
语音识别语法规范（SRGS）定义了用于表示语音识别中使用的语法的语法，以便开发人员可以指定语音识别器要听的单词和单词模式。语法格式的语法有两种形式，一种是扩充BNF（ABNF）形式，另一种是XML形式。本文档中定义的相应媒体类型为“应用程序/srgs”和“应用程序/srgs+xml”。
The Call Control EXtensible Markup Language (CCXML) is an XML designed to provide telephony call control support for dialog systems, such as VoiceXML. The associated media type defined in this document is "application/ccxml+xml".
呼叫控制可扩展标记语言（CCXML）是一种XML，旨在为对话系统（如VoiceXML）提供电话呼叫控制支持。本文档中定义的相关媒体类型为“应用程序/ccxml+xml”。
The Pronunciation Lexicon Specification (PLS) defines an XML syntax for specifying pronunciation lexicons to be used by speech recognition and speech synthesis engines in voice browser applications. The associated media type defined in this document is "application/pls+xml".
语音词典规范（PLS）定义了一种XML语法，用于指定语音浏览器应用程序中语音识别和语音合成引擎使用的语音词典。本文档中定义的相关媒体类型为“应用程序/pls+xml”。

2. 注册应用程序/voicexml+xml、应用程序/ssml+xml、应用程序/srgs+xml、应用程序/ccxml+xml和应用程序/pls+xml

Various W3C Speech Interface Framework implementations use these media types.
各种W3C语音接口框架实现都使用这些媒体类型。
Several instructions in the cited specifications may cause arbitrary Uniform Resource Identifiers (URIs) to be dereferenced. In this case, the security issues of [RFC3986], section 7, should be considered.
引用规范中的多条指令可能导致任意统一资源标识符（URI）被取消引用。在这种情况下，应考虑[RFC3986]第7节的安全问题。
In addition, because of the extensibility features of those specifications, it is possible that the registered media types may describe content that has security implications beyond those described here. However, if the processor follows only the normative semantics of the specifications, this content will be ignored. Only in the case where the processor recognizes and processes the additional content, or where further processing of that content is dispatched to other processors, would security issues potentially arise. And in that case, they would fall outside the domain of this registration document.
此外，由于这些规范的可扩展性特征，注册的媒体类型可能描述具有超出此处所述安全含义的内容。但是，如果处理器仅遵循规范的规范语义，则此内容将被忽略。只有在处理者识别并处理附加内容的情况下，或者在将该内容的进一步处理分派给其他处理者的情况下，才可能出现安全问题。在这种情况下，它们将不属于本注册文件的范围。
Although no byte sequences can be counted on to always be present, XML MIME entities in ASCII-compatible charsets (including UTF-8) often begin with hexadecimal 3C 3F 78 6D 6C ("<?xml"), and those in UTF-16 often begin with hexadecimal FE FF 00 3C 00 3F 00 78 00 6D 00 6C or FF FE 3C 00 3F 00 78 00 6D 00 6C 00 (the Byte Order Mark (BOM) followed by "<?xml"). For more information, see Appendix F of [XML].
虽然不能指望总是存在字节序列，但ASCII兼容字符集（包括UTF-8）中的XML MIME实体通常以十六进制3C 3F 78 6D 6C（“XML”）开头，而UTF-16中的XML MIME实体通常以十六进制FE FF 00 3C 00 3F 00 78 00 6D 00 6C或FF FE 3C 00 3F 00 78 00 6D 00 6C 00（字节顺序标记（BOM）开头后跟“<？xml”）。有关更多信息，请参见[XML]的附录F。

The ABNF Form of SRGS follows the character encoding handling defined for XML: an ABNF grammar processor must accept both the UTF-8 and UTF-16 encodings of ISO/IEC 10646 and may support other character encodings.
SRG的ABNF格式遵循为XML定义的字符编码处理：ABNF语法处理器必须同时接受ISO/IEC 10646的UTF-8和UTF-16编码，并且可以支持其他字符编码。

Speech Recognition Grammar Specification Version 1.0 [SRGS]
语音识别语法规范1.0版[SRGS]
Various SRGS implementations use this media type.
各种SRG实现都使用这种媒体类型。
Several instructions in SRGS may cause arbitrary URIs to be dereferenced. In this case, the security issues of [RFC3986], section 7, should be considered.
SRG中的多条指令可能会导致任意URI被取消引用。在这种情况下，应考虑[RFC3986]第7节的安全问题。
In addition, because of the extensibility features of SRGS, it is possible that the registered media types may describe content that has security implications beyond those described here. However, if the processor follows only the normative semantics of the specifications, this content will be ignored. Only in the case where the processor recognizes and processes the additional content, or where further processing of that content is dispatched to other processors, would security issues potentially arise. In that case, they would fall outside the domain of this registration document.
此外，由于SRG的可扩展性特征，注册的媒体类型可能会描述具有超出此处所述安全含义的内容。但是，如果处理器仅遵循规范的规范语义，则此内容将被忽略。只有在处理者识别并处理附加内容的情况下，或者在将该内容的进一步处理分派给其他处理者的情况下，才可能出现安全问题。在这种情况下，它们将不属于本注册文件的范围。
The ABNF self-identifying header must be present in any legal stand-alone ABNF Form grammar document. The first character of an ABNF document must be the "#" symbol (x23) unless preceded by an optional XML 1.0 byte order mark. The ABNF byte order mark follows the XML definition and requirements. For example, documents encoded in UTF-16 must begin with the byte order mark. The optional byte order mark and required "#" symbol must be followed immediately by the exact string "ABNF" (x41 x42 x4d x46) or the appropriate equivalent for the document's encoding (e.g., for UTF-16 little-endian: x23 x00 x41 x00 x42 x00 x4d x00 x46 x00). If the byte order mark is absent on a grammar encoded in UTF-16, then the grammar processor should perform auto-detection of character encoding in a manner analogous to auto-detection of character encoding in XML. Next follows a single-space character (x20) and the required version number, which is "1.0" for this specification (x31 x2e x30).
ABNF自识别头必须出现在任何合法的独立ABNF格式语法文档中。ABNF文档的第一个字符必须是“#”符号（x23），除非前面有可选的XML 1.0字节顺序标记。ABNF字节顺序标记遵循XML定义和要求。例如，以UTF-16编码的文档必须以字节顺序标记开头。可选的字节顺序标记和所需的“#”符号后面必须紧跟着精确的字符串“ABNF”（x41 x42 x4d x46）或文档编码的相应等效字符串（例如，对于UTF-16小端码：x23 x00 x41 x00 x42 x00 x4d x00 x46 x00）。如果UTF-16中编码的语法上没有字节顺序标记，那么语法处理器应该以类似于XML中字符编码的自动检测的方式执行字符编码的自动检测。接下来是一个空格字符（x20）和所需的版本号，对于本规范（x31 x2e x30），该版本号为“1.0”。
