Overview
概述
This document describes the registration of the MIME sub-type multipart/voice-message for use with the Voice Profile for Internet Mail (VPIM). A full description of usage can be found in the VPIM v2 specification.
本文档描述了MIME子类型multipart/voice message的注册，以与Internet邮件语音配置文件（VPIM）一起使用。在VPIM v2规范中可以找到使用的完整描述。
This document describes the registration of the MIME sub-type multipart/voice-message for use with the Voice Profile for Internet Mail (VPIM). A full description of usage can be found in the VPIM v2 specification [VPIM2]. This document revises an earlier sub-type registration in RFC 1911 [VPIM1].
本文档描述了MIME子类型multipart/voice message的注册，以与Internet邮件语音配置文件（VPIM）一起使用。在VPIM v2规范[VPIM2]中可以找到使用的完整说明。本文件修订了RFC 1911[VPIM1]中较早的子类型注册。
The VPIM specification defines a restricted profile of the Internet multimedia messaging protocols for use between voice processing platforms. These platforms have historically been special-purpose computers and often do not have the same facilities normally associated with a traditional Internet Email-capable computer. As a result, VPIM also specifies additional functionality as it is needed. The profile is intended to specify the minimum common set of features to allow interworking between compliant systems.
VPIM规范定义了在语音处理平台之间使用的Internet多媒体消息协议的受限配置文件。这些平台在历史上一直是专用计算机，通常没有与传统的支持Internet电子邮件的计算机相关的相同设施。因此，VPIM还根据需要指定其他功能。该配置文件旨在指定允许兼容系统之间互通的最小通用功能集。
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [REQ].
本文件中的关键词“必须”、“不得”、“要求”、“应”、“不应”、“应”、“不应”、“建议”、“可”和“可选”应按照[REQ]中的说明进行解释。
The MIME sub-type multipart/voice-message is defined to hold specific media contents that are interchanged in messages between voice messaging systems described in [VPIM2]. Essentially, the sub-type provides a simple wrapper that easily identifies the entire content as being the components of a single voice message. The sub-type is identical in semantics and syntax to multipart/mixed, as defined in [MIME2]. As such, it may be safely interpreted as a multipart/mixed by systems that do not understand the sub-type (only the identification as a voice message would be lost).
MIME子类型multipart/voice message被定义为保存在[VPIM2]中描述的语音消息系统之间交换的消息中的特定媒体内容。本质上，子类型提供了一个简单的包装器，可以轻松地将整个内容标识为单个语音消息的组件。子类型在语义和语法上与multipart/mixed相同，如[MIME2]中所定义。因此，不理解子类型的系统可以安全地将其解释为多部分/混合（只有作为语音消息的标识才会丢失）。
This mechanism allows the insertion of an explanatory preamble (e.g. VPIM voice message attached) for recipients who read the message with pre-MIME software, since the preamble will be ignored by MIME-compliant software.
此机制允许为使用MIME前软件阅读邮件的收件人插入解释性前导（例如附加VPIM语音邮件），因为MIME兼容软件将忽略前导。
In addition to the MIME required boundary parameter, a version parameter is also required for this sub-type. This is to distinguish, this refinement of the sub-type from the previous definition in [VPIM1]. The value of the version parameter is "2.0" if the content conforms to the requirements of [VPIM2]. Should there be further revisions of this content type, there MUST be backwards compatibility (i.e. systems implementing version n can read version 2, and systems implementing version 2 can read version 2 contents within a version n). The default version value (when the parameter is missing) is 1, indicating the content conforms to the requirements of [VPIM1].
除了MIME必需的边界参数外，此子类型还需要版本参数。这是为了将子类型的细化与[VPIM1]中先前的定义区分开来。如果内容符合[VPIM2]的要求，则版本参数的值为“2.0”。如果此内容类型有进一步的修订，则必须具有向后兼容性（即，实现版本n的系统可以读取版本2，而实现版本2的系统可以读取版本n中的版本2内容）。默认版本值（参数缺失时）为1，表示内容符合[VPIM1]的要求。
[VPIM2] describes the restriction that only specific media types, applicable to voice messaging, are valid `next-level' contents of this sub-type (when version=2.0). They are: audio/*, image/*, message/rfc822 and application/directory. The multipart provides for the packaging of as many of these contents as is necessary.
[VPIM2]描述了仅适用于语音消息的特定媒体类型是此子类型的有效“下一级”内容的限制（当版本=2.0时）。它们是：audio/*、image/*、message/rfc822和application/directory。multipart可根据需要对这些内容进行打包。
The multipart/voice-message sub-type is a primary component of the VPIM specification [VPIM2]. All VPIM Messages MUST contain this sub-type to identify the wrapping of a voice message. The contents of this wrapper can vary from only one audio/32KADPCM content to a complex set of related and nested contents.
多部分/语音消息子类型是VPIM规范[VPIM2]的主要组件。所有VPIM消息必须包含此子类型，以标识语音消息的包装。此包装的内容可以从一个音频/32KADPCM内容到一组复杂的相关嵌套内容不等。
Typically, if more than one audio segment is present, the first is the spoken name of the originator, the second is the spoken subject, and the third is the voice message itself. This order, however, MUST NOT be assumed in any case. Further, the order that the contents appear SHOULD be the order in which they are presented to the user.
通常，如果存在多个音频段，第一个是发起者的口头姓名，第二个是口头主题，第三个是语音消息本身。但是，在任何情况下都不得假定该命令。此外，内容出现的顺序应该是它们呈现给用户的顺序。
The spoken name segment, if available, shall contain the name of the message sender in the voice of the sender. The length of the spoken name segment must not exceed 12 seconds.
语音姓名段（如有）应包含发送者语音中的信息发送者姓名。语音姓名段的长度不得超过12秒。
The spoken subject segment, if available, shall contain the subject of the message sender in the voice of the sender. The length of the spoken subject segment must not exceed 20 seconds.
口语主题段（如有）应包含发送者语音中消息发送者的主题。口语主题段的长度不得超过20秒。
The directory information part, if present, will contain information specific to the orginator of the voice message.
目录信息部分（如果存在）将包含特定于语音消息来源的信息。

Required parameters: boundary, version
所需参数：边界、版本
The use of boundary is defined in [MIME2]
[MIME2]中定义了边界的使用
The version parameter that contains the value "2.0" if enclosed content conforms to [VPIM2]. The absence of this parameter indicates conformance to the previous version defined in RFC 1911 [VPIM1].
如果所附内容符合[VPIM2]，则包含值“2.0”的版本参数。缺少此参数表示符合RFC 1911[VPIM1]中定义的先前版本。
Optional parameters: none
可选参数：无
Encoding considerations: 7bit, 8bit or Binary
编码注意事项：7位、8位或二进制
Security considerations:
安全考虑：
This definition identifies the content as being a voice message. In some environments (though likely not the majority), the loss of the anonymity of the content may be a security issue.
此定义将内容标识为语音消息。在某些环境中（虽然可能不是大多数），内容的匿名性丢失可能是一个安全问题。
Interoperability considerations:
互操作性注意事项：
Systems developed to conform with [VPIM1] may not conform to this registration. Specifically, the required version will likely be absent, in this case the recipient system should still be able to accept the message and will be able to handle the content. The VPIM v1 positional identification, however, would likely be lost.
为符合[VPIM1]而开发的系统可能不符合本注册。具体来说，可能缺少所需的版本，在这种情况下，收件人系统应该仍然能够接受消息并能够处理内容。然而，VPIM v1位置标识可能会丢失。
