摘要
This document is a proposal to add a new event/signal package to the MGCP (Media Gateway Control Protocol) protocol to control an ARF (Audio Resource Function) which may reside on a Media Gateway or specialized Audio Server.
本文件建议在MGCP（媒体网关控制协议）协议中添加新的事件/信号包，以控制可能位于媒体网关或专用音频服务器上的ARF（音频资源功能）。
This event package provides support for the standard IVR (Interactive Voice Response) operations of PlayAnnouncement, PlayCollect, and PlayRecord. It supports direct references to simple audio as well as indirect references to simple and complex audio. It provides audio variables, control of audio interruptibility, digit buffer control, special key sequences, and support for reprompting during data collection. It also provides an arbitrary number of user defined qualifiers to be used in resolving complex audio structures. For example, the user could define qualifiers for any or all of the following: language, accent, audio file format, gender, speaker, or customer.
此事件包支持PlayAnnouncement、PlayCollect和PlayRecord的标准IVR（交互式语音响应）操作。它支持对简单音频的直接引用以及对简单和复杂音频的间接引用。它提供音频变量、音频可中断性控制、数字缓冲区控制、特殊按键序列，并支持数据采集期间的重新编程。它还提供了任意数量的用户定义限定符，用于解析复杂的音频结构。例如，用户可以为以下任何或所有内容定义限定符：语言、重音、音频文件格式、性别、扬声器或客户。

The following syntax supports both simple and complex audio structures. A simple audio structure might be a single announcement such as "Welcome to Bell South's Automated Directory Assistance Service". A more complex audio structure might consist of an announcement followed by voice variable followed by another announcement, for example "There are thirty seven minutes remaining on your prepaid calling card," where "There are" is a prompt, the number of minutes is a voice variable, and "minutes remaining on your prepaid calling card" is another prompt.
以下语法支持简单和复杂的音频结构。一个简单的音频结构可能是一个单独的公告，例如“欢迎使用Bell South的自动目录协助服务”。更复杂的音频结构可能包括一个公告，后跟语音变量，再后跟另一个公告，例如“预付费电话卡上还有37分钟”，其中“有”是一个提示，分钟数是一个语音变量，以及“预付费电话卡上还有分钟”这是另一个提示。
It is also possible to define complex audio structures that are qualified by user defined selectors such as language, audio file format, gender, accent, customer, or voice talent. For instance, if the above example were qualified by language and accent selectors, it would be possible to play "There are thirty seven minutes remaining on your prepaid calling card" in English spoken with a southern accent or in English spoken with a mid-western accent, providing that the audio to support this had been provisioned.
还可以定义由用户定义的选择器限定的复杂音频结构，如语言、音频文件格式、性别、口音、客户或语音天赋。例如，如果上述示例由语言和口音选择器限定，则可以使用带有南方口音的英语或带有中西部口音的英语播放“您的预付费电话卡上还有37分钟”，前提是已提供支持此功能的音频。
There are two methods of specifying complex audio. The first is to directly reference the individual components. This requires a complete description of each component to be specified via the protocol. The second method is to provision the components on the Audio Server as a single entity and to export a reference to that entity to the call agent. In this case, only the reference (plus any
指定复杂音频有两种方法。第一种方法是直接引用各个组件。这需要通过协议指定每个组件的完整描述。第二种方法是将音频服务器上的组件作为单个实体进行配置，并将对该实体的引用导出到调用代理。在这种情况下，只有引用（加上任何
dynamic data required, such as a variable data) is passed via the protocol, and no specification of individual components is necessary.
所需的动态数据（如变量数据）通过协议传递，不需要指定单个组件。
The Audio Server Package provides significant functionality most of which is controlled via protocol parameters. Most parameters are optional, and where ever possible default to reasonable values. An audio application that references to provisioned, complex audio structures, and which takes advantage of parameter optionality and defaults, can specify audio events using a minimum of syntax.
音频服务器包提供了重要的功能，其中大部分功能通过协议参数控制。大多数参数都是可选的，并且尽可能默认为合理的值。一个音频应用程序引用已配置的复杂音频结构，并利用参数可选性和默认值，可以使用最少的语法指定音频事件。
The next two sections contain background information which may be helpful in understanding the syntax.
接下来的两个部分包含可能有助于理解语法的背景信息。
The syntax supports abstractions of set and sequence for storing and referencing audio data.
该语法支持用于存储和引用音频数据的集合和序列的抽象。
A sequence is a provisioned sequence of one or more audio segments. Component segments are not necessarily all of the same type. Every sequence is assigned a unique segment id. On playback, a sequence id reference is deconstructed into its individual parts, each of which is played in order.
序列是一个或多个音频段的配置序列。组件段不一定都是同一类型。每个序列都分配了一个唯一的片段id。在播放时，序列id引用被分解为各个部分，每个部分都按顺序播放。
A set is a provisioned collection of audio segments with an associated selector. On playback, the selector value is resolved to a particular set element. Selector types are supported by the syntax, but individual selector types are not defined in the syntax except for the pre-defined language selector; they are instead defined by the user (i.e. provisioner). A user could define one or more of the following selector types: language, accent, audio file format, gender, accent, customer, or day of the week. For each selector type, the user must define a range of valid values. The user may also choose to define a default value. At runtime if a selector value is not supplied the default value is used.
集合是具有关联选择器的音频段的已配置集合。播放时，选择器值解析为特定的集合元素。语法支持选择器类型，但语法中未定义单个选择器类型，预定义语言选择器除外；它们由用户（即供应器）定义。用户可以定义以下一种或多种选择器类型：语言、重音、音频文件格式、性别、重音、客户或星期几。对于每个选择器类型，用户必须定义有效值的范围。用户还可以选择定义默认值。在运行时，如果未提供选择器值，则使用默认值。
For example, to support an application which plays a particular piece of audio in either English, French, or Russian, a provisioner would define a set with the pre-defined selector, "Lang", and would define three possible values for that selector, "eng", "fra", and "rus". The provisioner would then provision three recordings of the prompt, one in each language, and would associate the French recording with the "fra" selector value, etc. The provisioner also could define a default value of the selector when no selector value is supplied, "eng" for instance. The entire set would be assigned a unique segment id.
例如，为了支持以英语、法语或俄语播放特定音频片段的应用程序，供应器将使用预定义的选择器“Lang”定义一个集合，并将为该选择器定义三个可能的值“eng”、“fra”和“rus”。然后，provisioner将提供三条提示录音，每种语言一条，并将法语录音与“fra”选择器值等相关联。如果未提供选择器值，provisioner还可以定义选择器的默认值，例如“eng”。整个集合将被分配一个唯一的段id。
At runtime a reference to the set with the selector set to "rus" would result in the Russian version of the prompt being played. A reference to the set with no selector would result in the English version of the prompt being played since English has been set as the default selector value.
在运行时，对选择器设置为“rus”的集合的引用将导致播放俄语版本的提示。由于已将英语设置为默认选择器值，因此引用不带选择器的集合将导致播放英语版本的提示。
Nested definition of both sets and sequences is allowed, i.e. it legal to define a set of sets or a sequence of sequences. In addition, audio structures may also be specified by intermixing sets and sequences, and it is possible to specify a set of sequences or a sequence containing one or more set elements. Direct or transitive definition of a set or segment in terms of itself is not allowed.
允许对集合和序列进行嵌套定义，即定义集合集合或序列是合法的。此外，还可以通过混合集合和序列来指定音频结构，并且可以指定一组序列或包含一个或多个集合元素的序列。不允许对集合或段本身进行直接或传递性定义。
The syntax supports the following segment types:
该语法支持以下段类型：
RECORDING: A reference by unique id to a single piece of recorded audio.
录制：通过唯一id引用单个录制的音频。
RECORDINGs may be provisioned or they may be made during the course of a call. A RECORDING made during the course of a call can be temporary or persistent. A temporary RECORDING lasts only for the life of the call during which it was recorded. A persistent RECORDING lasts beyond the live of the call during which it was recorded.
录音可以设置，也可以在通话过程中录制。通话过程中的录音可以是临时的，也可以是持久的。临时录音仅在通话期间持续。持续录制持续时间超过录制期间的通话实况。
A provisioned RECORDING may be replaced (or overridden) by a persistent RECORDING. A reference to the id of the provisioned RECORDING will then resolve to the persistent RECORDING. The overriding persistent audio can subsequently be deleted and the original provisioned audio can be restored.
配置的记录可以被持久记录替换（或覆盖）。然后，对已设置录制的id的引用将解析为持久录制。随后可以删除覆盖的持久音频，并恢复原始配置的音频。
A provisioned RECORDING may be overridden more than once. In this case, the id of the provisioned RECORDING refers to the latest overriding RECORDING. When the overriding RECORDING is deleted, the original provisioned RECORDING is restored, even if the segment has been overridden multiple times.
配置的录制可能会被覆盖多次。在这种情况下，已设置记录的id指的是最新的覆盖记录。删除覆盖记录时，即使该段已被多次覆盖，也会恢复原始配置的记录。
TEXT: A reference to a block of text to be converted to speech or to be displayed on a device. Reference may be by unique id to a block of provisioned text or by direct specification of text in a parameter.
文本：对要转换为语音或在设备上显示的文本块的引用。引用可以是对已设置文本块的唯一id，也可以是对参数中文本的直接指定。
SILENCE: A specification of a length of silence to be played in units of 100 milliseconds.
静音：以100毫秒为单位播放的静音长度规格。
TONE: The specification of a tone to be played by algorithmic generation. Most tones however will probably be recorded, not generated. Exact specification of this segment type is tbd.
音调：通过算法生成播放的音调规范。然而，大多数音调可能会被录制，而不是生成。此段类型的确切规格待定。
VARIABLE: The specification of a voice variable by the parameters of type, subtype, and value. Specification of variables is considered in more detail in a subsequent section of this document.
变量：通过类型、子类型和值的参数指定语音变量。本文件后续章节将更详细地考虑变量规范。
SEQUENCE: A reference by unique id to a provisioned sequence of mixed RECORDING, TEXT, SILENCE, TONE, VARIABLE, SET, or SEQUENCE segments. Nested definition of SEQUENCE segments is allowed. Direct or transitive definition of a SEQUENCE segment in terms of itself is not allowed.
序列：通过唯一id对混合录音、文本、静音、音调、变量、集合或序列段的配置序列的引用。允许序列段的嵌套定义。不允许对序列段本身进行直接或传递性定义。
SET: A reference by unique id to a provisioned set of segments. The intended and recommended use of the SET type is that all segments in the set should be semantically equivalent, however there is no real way of enforcing this restriction either in the protocol or in provisioning. Every set has an associated selector which is used at runtime to resolve the set reference to a specific element of the set. The elements of a set may one of the following segment types: RECORDING, TEXT, TONE, SILENCE, SEQUENCE, or SET. Specific selector types are not specified by the protocol and must be defined by the user. Nested definition of SET segments is allowed. Direct or transitive definition of a SET segment in terms of itself is not allowed.
集合：通过唯一id对已设置的段集合的引用。集合类型的预期用途和推荐用途是集合中的所有段在语义上都应该是等效的，但是在协议或供应中都没有强制执行此限制的实际方法。每个集合都有一个关联的选择器，在运行时用于将集合引用解析为集合的特定元素。集合的元素可以是以下片段类型之一：录音、文本、音调、静音、序列或集合。协议未指定特定的选择器类型，必须由用户定义。允许对集合段进行嵌套定义。不允许对集合段本身进行直接或传递性定义。

The events provided by the AS Package are defined as follows:
AS包提供的事件定义如下：
PlayAnnouncement: Plays an announcement in situations where there is no need for interaction with the user. Because there is no need to monitor the incoming media stream this event is an efficient mechanism for treatments, informational announcements, etc.
PlayAnnouncement：在不需要与用户交互的情况下播放公告。因为不需要监控传入的媒体流，所以此事件是治疗、信息公告等的有效机制。
PlayCollect: Plays a prompt and collects DTMF digits entered by a user. If no digits are entered or an invalid digit pattern is entered, the user may be reprompted and given another chance to enter a correct pattern of digits. The following digits are supported: 0-9, *, #, A, B, C, D. By default PlayCollect does not play an initial prompt, makes only one attempt to collect digits, and therefore functions as a simple Collect operation. Various special purpose keys, key sequences, and key sets can be defined for use during the PlayCollect operation.
PlayCollect：播放提示并收集用户输入的DTMF数字。如果未输入任何数字或输入了无效的数字模式，则可能会重新提示用户，并给用户另一次输入正确数字模式的机会。支持以下数字：0-9、*、#、A、B、C、D。默认情况下，PlayCollect不播放初始提示，只尝试一次收集数字，因此可以作为简单的收集操作。可以定义各种专用键、键序列和键集，以便在PlayCollect操作期间使用。
PlayRecord: Plays a prompt and records user speech. If the user does not speak, the user may be reprompted and given another chance to record. By default PlayRecord does not play an initial prompt, makes only one attempt to record, and therefore functions as a simple Record operation.
播放录制：播放提示并录制用户讲话。如果用户不说话，用户可能会被重新点名，并获得另一次录音机会。默认情况下，PlayRecord不播放初始提示，只尝试录制一次，因此其功能相当于一个简单的录制操作。
OperationComplete: Detected upon the successful completion of a Play, PlayRecord, or Play Collect signal.
操作完成：在成功完成播放、播放录制或播放采集信号时检测到。
OperationFailed: Detected upon the failure of a Play, PlayRecord, or PlayCollect signal.
操作失败：在播放、播放录制或播放采集信号失败时检测到。
EndSignal: Gracefully terminates a Play, PlayCollect, or PlayRecord signal. For each of these signals, if the signal is terminated with the EndSignal signal the resulting OperationComplete event or OperationFailed event will contain all the parameters it would normally, including any collected digits or the recording id of the recording that was in progress when the EndSignal signal was received.
EndSignal：优雅地终止播放、播放收藏或播放录制信号。对于这些信号中的每一个，如果信号以EndSignal信号终止，则产生的OperationComplete事件或OperationFailed事件将包含正常情况下的所有参数，包括接收EndSignal信号时收集的任何数字或正在进行的记录的记录id。
If an Advanced Audio Package signal is active on an endpoint and another signal of the same type is applied, the two signals including parameters and parameter values will compared If the signals are identical, the signal in progress will be allowed to continue and the new signal will be discarded. Because of this behavior the Advanced Audio Package may not interoperate well with some other packages such as the Line and Trunk packages.
如果端点上的高级音频包信号处于活动状态，并且应用了另一个相同类型的信号，则将比较包括参数和参数值的两个信号。如果信号相同，则允许进行中的信号继续，并丢弃新信号。由于这种行为，高级音频包可能无法与一些其他包（如Line和Trunk包）很好地互操作。
The PlayAnnouncement, PlayRecord, and PlayCollect events may each be qualified by a string of parameters, most of which are optional. Where appropriate, parameters default to reasonable values. The only event with a required parameter is PlayAnnouncement. If a Play-Announcement event is not provided with a parameter specifying some form of playable audio an error is returned to the application.
PlayAnnouncement、PlayRecord和PlayCollect事件都可以由一系列参数限定，其中大多数参数是可选的。在适当的情况下，参数默认为合理的值。唯一具有必需参数的事件是PlayAnnouncement。如果播放公告事件未提供指定某种形式的可播放音频的参数，则会向应用程序返回错误。
These parameters are shown in the following table:

Segment Identifier:
段标识符：
A 32 bit binary integer identifying a provisioned entity such as a recording, set, sequence, etc.
一种32位二进制整数，用于标识已配置的实体，如记录、集合、序列等。
Text To Speech:
文字转语音：
Specifies a text string to be converted to speech.
指定要转换为语音的文本字符串。
Display Text:
显示文本：
Specifies a text string to be displayed on a device.
指定要在设备上显示的文本字符串。
Silence:
沉默：
Specifies a length of silence to be played in units of 100 milliseconds.
指定以100毫秒为单位播放的静音长度。
Tone:
语气：
Specifies a tone to be played by algorithmic generation. Exact specification of this parameter is tbd. Most tones will likely be recorded, not generated.
指定算法生成要播放的音调。此参数的确切规格待定。大多数音调可能会被录制，而不是生成。
Variable:
变量：
Specifies a voice variable by type, subtype, and value. Variables are more completely defined in a subsequent section of the document.
按类型、子类型和值指定语音变量。变量在文档的后续部分中有更完整的定义。
The syntax supports two kinds of variables. Embedded embedded variables are variables that have been provisioned as part of a segment. Standalone variables are completely specified in the protocol message.
该语法支持两种类型的变量。嵌入式变量是作为段的一部分提供的变量。独立变量完全在协议消息中指定。
Typically embedded variables are provisioned along with recorded speech, e.g. "A representative will be with you in approximately 5 minutes. If you would prefer to leave a voice message, press 1 now". where the variable is the number of minutes. This kind of variable is often referred to as an embedded variable.
通常，嵌入式变量与录制的语音一起提供，例如“代表将在大约5分钟后与您见面。如果您希望留下语音信息，请立即按1”。其中变量是分钟数。这类变量通常被称为嵌入变量。
Variables are specified by the following parameters: type, subtype, and value. Variable types include Date, Money, Number, Time, etc. Subtype is a refinement of type. For example the variable type Money might have an associated range of subtypes such as Dollar, Rupee, Dinar, etc. Not all variables require a subtype, and for these variables the subtype parameter should be set to null.
变量由以下参数指定：类型、子类型和值。变量类型包括日期、货币、数字、时间等。子类型是类型的细化。例如，变量类型Money可能具有关联的子类型范围，如美元、卢比、第纳尔等。并非所有变量都需要子类型，对于这些变量，子类型参数应设置为null。
For embedded variables, the type and subtype must be provisioned. The value may be provisioned. If it is not provisioned it must be specified as part of the variable reference. In a list of segments, an embedded variable value specification applies only to the segment that directly precedes it. If a segment has multiple embedded variables, the values must be given in the order in which the variables are encountered when the segment is played.
对于嵌入变量，必须设置类型和子类型。可以设置该值。如果未设置，则必须将其指定为变量引用的一部分。在段列表中，嵌入式变量值规范仅适用于直接位于其前面的段。如果一段有多个嵌入变量，则必须按照播放该段时遇到变量的顺序给出值。
Some examples follow below:
以下是一些例子：
A standalone variable:
独立变量：
S: pa(an=vb(mny,usd,1153))
S: pa(an=vb(mny,usd,1153))
An embedded variable:
嵌入变量：
S: pa(an=37<1153>)
S: pa(an=37<1153>)
Not all variables, such as the date variable shown in the next example, require a subtype. In that case, the subtype is encoded with the value "null":
并非所有变量（如下一个示例中显示的日期变量）都需要子类型。在这种情况下，子类型使用值“null”进行编码：
S: pa(an=vb(dat,null,101598))
S: pa(an=vb(dat,null,101598))
In some cases it may be desirable to play an announcement that contains an embedded variable without playing the variable itself. To do this a single "null" is provided for the value:
在某些情况下，可能需要播放包含嵌入变量的公告，而不播放变量本身。为此，为该值提供一个“null”：
S: pa(an=37<null>)
S: pa(an=37<null>)

|GTQ | 320 | Quetzal | Guatemala |
|___________|______________|__________|___________________|
Money can be specified in negative or positive units of currency. In the above example "-110" would be spoken as "minus one dollar and ten cents".
货币可以指定为负或正的货币单位。在上面的例子中“-110”将被称为“减去一美元十美分”。

Speaks a time in either twelve hour format or twenty four hour format depending on the specified subtype. For example "1700" is spoken as "Five pm" in twelve hour format or as "Seventeen hundred hours" in twenty four hour format. Specification is in HHMM format per ISO 8601, International Data and Time Notation [7].
根据指定的子类型，以12小时格式或24小时格式表示时间。例如，“1700”在12小时格式中被称为“下午5点”，在24小时格式中被称为“1700小时”。规范采用符合ISO 8601《国际数据和时间符号》[7]的HHMM格式。
Tone:
语气：
Plays an algorithmically generated tone, specification of which is tbd. Probably most applications will use prerecorded tones.
播放算法生成的音调，其规格为tbd。可能大多数应用程序都会使用预先录制的音调。
Weekday:

Speaks the day of the week, e.g. "Monday". Weekdays are specified as single digits, with "1" denoting Sunday, "2" denoting Monday, etc.
表示一周中的某一天，例如“星期一”。工作日指定为个位数，“1”表示星期天，“2”表示星期一等。
Selector types, except for the pre-defined "Lang" (language) selector, are definable by the user and may be applied to an individual segment within an operation or to all the segments in an operation. For each selector type, the user must also define a range of values that the selector can assume.
除预定义的“Lang”（语言）选择器外，选择器类型可由用户定义，并可应用于操作中的单个段或操作中的所有段。对于每种选择器类型，用户还必须定义选择器可以假定的值范围。
For example, if the user defines a selector of type "phase-of-the-moon", he might also define the legal values for that selector to be "new", "half", "full", "harvest", and "blue". For the selector to actually work at runtime, audio associated with each of the selector values must be provisioned.
例如，如果用户定义了类型为“月亮相位”的选择器，他还可以将该选择器的合法值定义为“新”、“半”、“满”、“收获”和“蓝色”。要使选择器在运行时实际工作，必须提供与每个选择器值关联的音频。
Although not required, it is suggested that the three letter codes defined in ISO standard 639-2, Code For The Representation Of Names Of Languages [4] be used as values for user defined language selectors. A small excerpt from ISO 639-2 follows:
虽然没有要求，但建议将ISO标准639-2中定义的三字母代码，即语言名称表示代码[4]用作用户定义语言选择器的值。ISO 639-2的小摘录如下：

Selectors can apply to entire operations or to a segment within an operation. If an operation contains multiple segments, each segment may have its own set of selectors. If selectors for an individual segment and selectors for the entire operation are present, the selector for the individual segment takes precedence for that segment. The selectors for the operation apply to all segments within that operation that do not have individual segment selectors. If a selector set is not specified, provisioned defaults are used.
选择器可以应用于整个操作或操作中的某个段。如果一个操作包含多个段，则每个段可能有自己的选择器集。如果存在单个段的选择器和整个操作的选择器，则单个段的选择器优先于该段。该操作的选择器适用于该操作中没有单独段选择器的所有段。如果未指定选择器集，则使用已设置的默认值。
Selectors are applied to variables only after the variable has been resolved. For instance if a date variable resolved to "October 15th, 1998" the voice with which the variable is spoken could resolve to either male or female if a gender selector had been defined.
选择器仅在解析变量后应用于变量。例如，如果一个日期变量解析为“1998年10月15日”，那么在定义了性别选择器的情况下，使用该变量的声音可以解析为男性或女性。
Aliasing of audio segments is supported. The alias to segment id mapping is provisioned and at runtime the alias is resolved to its associated segment id. The syntax for an alias is inclusion of the alias between two forward slashes, e.g.:
支持音频段的别名。设置别名到段id的映射，并在运行时将别名解析为其关联的段id。别名的语法是在两个正斜杠之间包含别名，例如：
S: pa(an=/not-in-service/)
S: pa(an=/not-in-service/)
This section presents a number of examples of how the syntax is used. Note that arguments to an event are separated by a one or more whitespace characters, which can be either an ASCII space character or an ASCII tabulation character.
本节介绍了一些如何使用语法的示例。请注意，事件的参数由一个或多个空格字符分隔，空格字符可以是ASCII空格字符或ASCII制表字符。
Play an announcement that consists of a single segment:
播放由单个片段组成的公告：
S: pa(an=39)
S: pa(an=39)
Play an announcement that consists of multiple segments:
播放由多个片段组成的公告：
S: pa(an=39,40,47)
S: pa(an=39,40,47)
Play an announcement that consists of a recording followed by silence followed by text to speech followed by a standalone voice variable:
播放一条公告，该公告由录音、静音、文字到语音、独立语音变量组成：
S: pa(an=39 si(30) ts(hello) vb(my,usd,3999))
S: pa(an=39 si(30) ts(hello) vb(my,usd,3999))
Play an announcement with an embedded variable. If the first three segments of the previous announcement were provisioned as segment 40, the following would be exactly equivalent to the play in the preceding example:
播放带有嵌入变量的公告。如果先前公告的前三个片段被设置为片段40，则以下内容将完全等同于上例中的剧本：
S: pa(an=40<3999>)
S: pa(an=40<3999>)
Play an announcement with two embedded variables:
使用两个嵌入变量播放公告：
S: pa(an=113<3999,10151998>)
S: pa(an=113<3999,10151998>)
Play a prompt and collect a single digit. If need be, play a reprompt, a no digits prompt, and a success or failure announcement. Give the user three attempts to enter a digit:
播放提示并收集单个数字。如果需要，播放重播、无数字提示和成功或失败公告。给用户三次输入数字的尝试：
S: pc(ip=21 rp=109 nd=102 fa=81 sa=72 na=3)
S: pc(ip=21 rp=109 nd=102 fa=81 sa=72 na=3)
Play a prompt and collect a single digit. If the user does not enter a digit replay the initial prompt. Give the user three attempts to enter a digit:
播放提示并收集单个数字。如果用户未输入数字，则重播初始提示。给用户三次输入数字的尝试：
S: pc(ip=21 na=3)
S: pc(ip=21 na=3)
Play a prompt and record voice. If the user does not speak play a no speech prompt. Give the user two attempts to record:
播放提示并录制语音。如果用户不说话，则播放无语音提示。给用户两次尝试记录的机会：
S: pr(ip=22 ns=42 na=2)
S: pr(ip=22 ns=42 na=2)
Play an announcement at ninety percent of its original speed and five decibels softer than its original volume. Play the announcement three times with two seconds of silence between plays.
以90%的原始速度播放公告，比原始音量低5分贝。播放公告三次，两次播放之间保持两秒钟的沉默。
S: pa(an=27 sp=90 vl=-5 it=3 iv=20)
S: pa(an=27 sp=90 vl=-5 it=3 iv=20)
Give the user two attempts to enter a three digit pattern. Clear the digit buffer before playing the prompt. The user can signal end of input using the # key, which is not returned to the call agent with the collected digits.
给用户两次输入三位数模式的尝试。播放提示之前，请清除数字缓冲区。用户可以使用#键发出输入结束的信号，该键不会使用收集的数字返回给呼叫代理。
S: pc(ip=43 cb=true mn=3 mx=3 na=2)
S: pc(ip=43 cb=true mn=3 mx=3 na=2)
Give the user three attempts to enter a three digit pattern. If the user enters one digits or two digits on the first or second attempts a reprompt is played. If the user enters no digits on the first or second attempts a no digits reprompt is played. If all three attempts fail, a failure announcement is played. If one of the attempts is successful, a success announcement is played and the collected digits are returned to the call agent. The user can signal end of input using the # key. If the # key terminates a successful input attempt, the collected digits, but not the # key, are returned to the call agent.
给用户三次输入三位数模式的尝试。如果用户在第一次或第二次尝试时输入一位或两位数字，则会播放重发。如果用户在第一次或第二次尝试时未输入任何数字，则会播放“无数字重发”。如果三次尝试均失败，则播放失败公告。如果其中一次尝试成功，将播放成功公告，并将收集到的数字返回给呼叫代理。用户可以使用#键发出输入结束的信号。如果#键终止了成功的输入尝试，则收集的数字（而不是#键）将返回给呼叫代理。
S: pc(ip=87 rp=5 nd=409 fa=9 sa=18 mx=3 na=3)
S: pc(ip=87 rp=5 nd=409 fa=9 sa=18 mx=3 na=3)
Give the user a single attempt to enter a a 1 to 4 digit pattern, allow 8 seconds for the user to enter the first digit, and allow 6 seconds for the user to enter each subsequent digit. If the subsequent digit timer expires after the user has less than four digits, the digits collected are returned to the call agent. The user can signal end of input using the # key which is not returned to the call agent with the collected digits.
给用户一次输入1到4位数字的尝试，给用户8秒钟的时间输入第一位数字，给用户6秒钟的时间输入后面的每个数字。如果随后的数字计时器在用户少于四个数字后过期，则收集的数字将返回给呼叫代理。用户可以使用#键发出输入结束的信号，该键不会使用收集的数字返回给呼叫代理。
S: pc(ip=4 fdt=80 idt=60 mx=4)
S: pc(ip=4 fdt=80 idt=60 mx=4)
Give the user three chances to enter an 11 digit number that begins with 0 or 1. If the user makes a mistake while entering digits, he can press the * key to discard any digits already collected, replay the prompt, and resume collection.
给用户三次机会输入以0或1开头的11位数字。如果用户在输入数字时出错，他可以按*键放弃任何已收集的数字，重放提示，然后继续收集。
S: pc(ip=33 mn=11 mx=11 sik=01 rsk=* na=3)
S: pc(ip=33 mn=11 mx=11 sik=01 rsk=* na=3)
Give the user three chances to enter an 11 digit number that begins with 0 or 1. If the user makes a mistake while entering digits, he can press the key sequence *11 to discard any digits already collected, replay the prompt, and resume collection. If the user enters the key sequence *12 the play collect is terminated along with any queued events, and the terminating key sequence is returned to the call agent for processing.
给用户三次机会输入以0或1开头的11位数字。如果用户在输入数字时出错，他可以按sequence*11键放弃任何已收集的数字，重放提示，然后继续收集。如果用户输入密钥序列*12，则播放收集将与任何排队事件一起终止，并且终止的密钥序列将返回给呼叫代理进行处理。
S: pc(ip=33 mn=11 mx=11 sik=01 rsk=*11 rtk=*12 na=3)
S: pc(ip=33 mn=11 mx=11 sik=01 rsk=*11 rtk=*12 na=3)
Give the user two chances to make a recording. After playing the prompt, wait 5 seconds for the user to speak, otherwise replay the initial prompt and try again. If the user does speak, wait for seven seconds after speech stops to make sure the user is finished. If the recording is successful, return a reference to the recording to the call agent.
给用户两次录音的机会。播放提示后，请等待5秒钟，等待用户讲话，否则请重播初始提示并重试。如果用户确实讲话，请在语音停止后等待七秒钟，以确保用户已完成。如果录制成功，请向呼叫代理返回对录制的引用。
S: pr(ip=6 prt=50 pst=70 na=2)
S: pr(ip=6 prt=50 pst=70 na=2)
Play an announcement in the default language:
以默认语言播放公告：
S: pa(an=5)
S: pa(an=5)
Play the same announcement the English. In the first example, the selector applies to the an segment; in the second it applies to the pa operation. For these particular examples, the net effect is the same.
在英语中播放相同的广播。在第一个示例中，选择器应用于A段；在第二种情况下，它适用于pa操作。对于这些特定的例子，净效应是相同的。
S: pa(an=5[Lang=eng]) or S: pa(an=5)[Lang=eng]
S: pa(an=5[Lang=eng]) or S: pa(an=5)[Lang=eng]
Play an announcement in Danish using a female voice with a Cajun accent.
用带有卡津口音的女声用丹麦语播放公告。
S: pa(an=6)[Lang=dan,gender=female,accent=cajun]
S: pa(an=6)[Lang=dan,gender=female,accent=cajun]
Play the first part of an announcement in English, the second part in the default language, and the third part in French.
用英语播放公告的第一部分，用默认语言播放第二部分，用法语播放第三部分。
S: pa(an=5[Lang=eng],6,7[Language=fra])
