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.
