VoiceXML Properties group

Note:

Most of these default values can be overridden either in the VoiceXML application itself or in the application parameters when you add the application to Experience Portal.

Field

Description

Language

The default application language.

Confidence Threshold

The default confidence level below which the ASR engine rejects the input from the caller.

Sensitivity Level

How loud an utterance must be for the ASR engine to start speech recognition. The higher the sensitivity level, the lower the input volume required to start speech recognition.

This value is mapped to whatever scale the ASR engine uses to compute the sensitivity level for speech recognition.

Speed vs. Accuracy

The balance between speed of recognition and accuracy of recognition.

This value is mapped to whatever scale the ASR engine uses to compute the balance between speed and accuracy of recognition.

N Best List Length

The maximum number of recognition results that the ASR engine can return.

Fetch Timeout

The maximum number of seconds that the VoiceXML browser should wait for the application server to return the requested page.

If this time elapses with no response from the application server, the CCXML browser cancels the request and runs the application's default error page.

Output Modes

Select the output mode for a media track.

The options are:

Maximum Recording Duration

The maximum recording time allowed.

Alarm Event Interval

The interval, in seconds, that determines the number of times the same type of error is logged to Log Viewer. If the same type of error occurs more than once in the specified interval, the error is logged to Log Viewer only once. This functionality ensures that the number of repetitive errors logged to Log Viewer are reduced.

Maximum Cache Age section

Document

The maximum length of time that a document can be in the cache before the application considers it to be stale and forces the MPP to download the document again.

Grammar

The maximum length of time that an utterance can be in the cache before the application considers it to be stale and forces the MPP to download the utterance again.

Note:

This value is the same as the Maximum Grammar Cache Age application parameter, and Experience Portal uses it in conjunction with the Maximum Grammar Staleness and Minimum Grammar Freshness Time application parameters in order to determine whether to force the MPP to download the utterance again.

Audio

The maximum length of time that an audio file can be in the cache before the application considers it to be stale and forces the MPP to download the audio file again.

Script

The maximum length of time that a script can be in the cache before the application considers it to be stale and forces the MPP to download the script again.

Data

The maximum length of time that data can be in the cache before the application considers it to be stale and forces the MPP to download the data again.

VoiceXML Browser Properties group

Field

Description

Maximum Branches

Maximum number of JavaScript branches for each JavaScript evaluation, that are used to interrupt infinite loops from (possibly malicious) scripts.

Cache section

Total Size

The maximum size for the AVB cache.

Once this size is reached, Experience Portal cleans the cache until size specified in the Low Water field is reached.

Low Water

The size that you want the AVB cache to be after it is cleaned.

Maximum Entry Size

The maximum individual file size to cache. This field has to be less than Total Size value. File that exceeds the size limit is not fetched.

Entry Expiration Time

You should obtain the lock before reading or writing files in the cache. If the lock is not available, the entry expiration time is used to periodically check its availability.

Interpreter section

Maximum Documents

The maximum number of pages that the AVB can access in a single session.

Maximum Execution Context Stack Depth

The maximum number of scripting context threads that can be stored simultaneously in the AVB.

Maximum Loop Iterations

Prevents voice browser from entering into an infinite loop while handling VXML events. If number of entries to event handling function exceeds the limit, the application exits.

INET section

Proxy Server

If your site uses an INET Proxy server, the fully qualified path to the proxy server.

Proxy Port

If your site uses an INET Proxy server, the port number for the proxy server.

SSL Verify

The options are:

Connection Persistent

Whether a new connection is established for each HTTP request.

The options are:

CCXML Browser Properties group

Field

Description

Fetch Timeout

The maximum number of seconds that the CCXML browser should wait for the application server to return the requested page.

If this time elapses with no response from the application server, the CCXML browser cancels the request and runs the application's default error page.

Enter a number between 1 and 65535. The default is 15.

Number of Threads for Asynchronous Fetch

The maximum number of threads that the CCXML browser should use for an asynchronous fetch.

Enter a number between 1 and 500. The default is 5.

Maximum Branches

Maximum number of JavaScript branches for each JavaScript evaluation, that are used to interrupt infinite loops from (possibly malicious) scripts.

Enter a value in the range 1 to 999999. The default is 100000.
