Record Block

The Record block records voice input from the caller. Also see Number of Allowed Attempts Exceeded Property. In case of user input blocks (Menu, Input, Record, Transfer), Composer adds a global variable  of type "Block" to the variables list.  You can conveniently use this variable for accessing the user input value. The Record block has the following properties: Record Block Exception Events The Record block has four exception events as described in Exception Event Descriptions:

• error
• error.badfetch
• noinput]] (supported by default)
• error.com.genesyslab.composer.recordCapture.failure

2. In the Value field, type a value for the allowable final silence before recording is stopped.

Max Duration Property

In the context of a Record block, the Max Duration property specifies the maximum recording duration. The default is 60 seconds.

To provide a value for the maximum recording duration:

1. Select the Max Duration row in the block's property table.
2. In the Value field, type a value for the maximum recording duration.

For more information on this property, refer to the Record VXML tag topic in GVP 8.1 Voice XML Help.

Min Duration Property

In the context of a Record block, the Min Duration property specifies the minimum allowed recording duration. The default is 1 second. To provide a value for the minimum recording duration:

1. Select the Min Duration row in the block's property table.
2. In the Value field, type a value for the minimum recording duration.

Capture Filename Property

A value for the Capture Filename property is required when the Capture Filename Type property is set to the value useSpecified. To provide a filename for the captured recording:

1. Select the Capture Filename row in the block's property table.
2. In the Value field, you can:

• Type a name for the recording file.
• Click the down arrow and select a variable.

Capture Filename Prefix Property

A value for the Capture Filename Prefix property is required when the Capture Filename Type property is set to the value usePrefix. To provide a prefix for the captured recording filename:

1. Select the Capture Filename Prefix row in the block's property table.
2. In the Value field, you can:
   • Type a value for the recording file prefix.
   • Click the down arrow and select a variable.

Capture Filename Type Property

The Capture Filename Type property indicates the type of the filename for saving the recording. To assign a value to the Capture Filename Type property:

1. Select the Capture Filename Type row in the block's property table.
2. In the Value field, select one of the following from the drop-down list:

• auto-generate a recording filename.
• usePrefix' to add the prefix value specified in the Capture Filename Prefix property to the default name that is generated for the recording.
• useSpecified to use the value specified in the Capture Filename property as the filename for the recording. In this case, the file will be overwritten for each call.

Capture Location Property

The Capture Location property specifies the destination path on the Web Application server where the recording is to be saved.

If no location is specified, the recordings are saved in the working directory the web application server process. This location may change depending on the web server environment, and therefore, it is recommended that a fixed location is always specified in the Capture Location property. To specify a capture (recording) location:

1. Click the Capture Location row in the block's property table.
2. Type a file path where the recording is to be saved that is located on the web server hosting the application. If the web server is running on Linux, a UNIX-style path can be entered. Composer will not validate the path.

Security Property

When the Security property is set to true, data for this block is treated as private. GVP will consider the data associated with this block as sensitive and will suppress it in platform logs and metrics. To assign a value to the Security property:

1. Select the Security row in the block's property table.
2. In the Value field, select true or false from the drop-down list.

Use Last Reprompt Indefinitely Property

If you set the Use Last Reprompt Indefinitely property to true, the application uses your last reprompt as the prompt for all further retries. Therefore, the exception handlers that come out for nomatch and noinput are redundant--even if you set the default exceptions that come out as red dots on the left-side of the block. To assign a value to the Use Last Reprompt Indefinitely property:

1. Select the Use Last Reprompt Indefinitely row in the block's property table.
2. In the Value field, select true or false from the drop-down list.

Get Shadow Variables Property

Shadow variables (optional) provide a way to retrieve further information regarding the value of an input item. They can provide platform-related information about the interaction/input. For example, for speech recognition, this may be the confidence level the platform receives from the ASR engine about how closely the engine could match the user utterance to specified grammar. By setting this property to true, it will expose the block’s shadow variable within the callflow. When enabled, the shadow variable will be included in the list of available variables. (For example, the Log block’s Logging Details will show Record1$.) A shadow variable is referenced as blockname$.shadowVariable, where blockname is the value of the input item's name attribute, and shadowVariable is the name of a specific shadow variable, for example: Record1$.duration. To assign a value to the Get Shadow Variables property:

1. Select the Get Shadow Variables row in the block's property table.
2. In the Value field, select true or false from the drop-down list.

Number of Retries Allowed Property

The Number Of Retries Allowed property determines how many opportunities the user will be provided to re-enter the value. If Use Last Prompt Indefinitely is set to true, this property has no effect; otherwise, the error.com.genesyslab.composer.toomanynomatches or error.com.genesyslab.composer.toomanynoinputs errors will be raised on reaching the maximum retry limit. To provide a value for the number of retries allowed:

1. Select the Number Of Retries Allowed row in the block's property table.
2. In the Value field, type a value for the number of retries that will be allowed.

Retry Prompts Property

Find this property's details under Common Properties. Starting with 8.1.410.14, validation displays a warning message if a resource file does not exist.

Use Original Prompts Property

If you set the Use Original Prompts property to true, in the event of an error requiring a retry, the application first plays back the retry error prompt, and then plays back the original prompt for the block (as specified in the Prompts property). To assign a value to the Use Original Prompts property:

1. Select the Use Original Prompts row in the block's property table.
2. In the Value field, select true or false from the drop-down list.
