Speech Servers group

Field

Description

ASR

If this application uses Automatic Speech Recognition (ASR) resources, this field lets you select the ASR engine type that will be used.

Languages

Displays all the languages that application servers can use on this system.

Select an individual entry in this list by clicking on it, or use Ctrl+Click and Shift+Click to select multiple entries.

Then, click to move the selected languages to the Selected Languages field. To move the languages back from the Selected Languages field to the Languages field, click .

This list is prepopulated with the list of the languages that were available for the designated ASR engine type when Experience Portal was released. It is maintained in a special file on the Experience Portal system and is not automatically updated. You must verify that the languages you select here are actually installed and available on the target ASR server.

You can add more languages to this list by clicking Configuration>Speech Servers from the EPM menu and selecting Customize in the ASR tab.

Note:

If a speech application is configured to use more languages than are configured for any single ASR server, Experience Portal sends a No ASR Resource exception to the application. What happens then depends on the event handler that the application uses.

Selected Languages

All language(s) that you select in the Languages pane appear in this pane.

Resources

If an ASR speech server is selected, this field displays how the application acquires the ASR speech resource.

The options are:

  • Acquire on call start and retain: Acquires the ASR speech resource at the beginning of the call and retains the resource till the end of the call.

  • Acquire on first use and retain: Acquires the ASR speech resource on the first use of the speech request and retains the resource till the end of the call.

  • Acquire and release as needed: Acquires the ASR speech resource when needed and releases the resource immediately after the dialogue is completed.

    Note:

    Before selecting the Acquire and release as needed option, check the license agreement with the speech vendor whether it is okay to release an acquired ASR speech resource before disconnecting the call.

TTS

If this application uses Text-to-Speech (TTS) resources, this field lets you select the TTS engine type that will be used.

Voices

If a TTS engine is selected, this field displays the voices configured for the TTS servers of that engine type on the Experience Portal system.

Note:

You can switch languages within a single speech application, provided all the required languages are configured on the same TTS server. If a speech application is configured to use more language/voice combinations than are configured for any single TTS server, Experience Portal sends a No TTS Resource exception to the application. What happens then depends on the event handler that the application uses.

Selected Voices

Displays the selected voices that the TTS server is configured to use.

Speech Parameters group

Note:

If these fields are not displayed, click the group heading to expand the group.

Field

Description

ASR section

Confidence Threshold

The confidence level below which the ASR engine will reject the input from the caller.

This value is mapped to whatever scale the ASR engine uses to compute the confidence level. In the case of ASR engines that use MRCP, this value is mapped in a linear fashion to the range 0 to 100.

Sensitivity Level

How loud an utterance must be for the ASR engine 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.

No Input Timeout

The number of milliseconds the system waits for a caller to respond after the prompt is finished playing and before the system throws a No Input event.

Recognition Timeout

The number of milliseconds the system allows the caller to continue speaking before the system ends the recognition attempt and throws a maxspeechtimeout event.

Speech Complete Timeout

The number of milliseconds of silence required following user speech before the speech recognizer either accepts it and returns a result or reject it and returns a No Match event.

This value is used when the recognizer currently has a complete match of an active grammar, and specifies how long it should wait for more input declaring a match. By contrast, the incomplete timeout is used when the speech is an incomplete match to an active grammar.

Speech Incomplete Timeout

The number of milliseconds of silence following user speech after which a recognizer finalizes a result.

The incomplete timeout applies when the speech prior to the silence is an incomplete match of all active grammars. In this case, once the timeout is triggered, the speech recognizer rejects the partial result and returns a No Match event.

Maximum Grammar Cache Age

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.

When determining whether an utterance is stale or not, the application adds this time together with the value specified in the Maximum Grammar Staleness field and compares that to the age of the utterance plus the value in the Minimum Grammar Freshness Time field.

The maximum grammar cache age plus the maximum grammar staleness time must be greater than or equal to the age of the utterance plus the minimum grammar freshness time.

For example, if the:

  • Maximum grammar cache age is 60

  • Maximum grammar staleness is 20

  • Current utterance has been cached for 45 seconds.

  • Minimum grammar freshness time is 30

Then the application will accept the utterance from the MPP because the expression 60 + 20 > 45 + 30 evaluates as True.

Minimum Grammar Freshness Time

The minimum length of time beyond an utterance’s current age for which the utterance must remain fresh to be accepted by the application.

The application adds this value to the current age of the utterance and compares the result to the value in the Maximum Grammar Cache Age field plus the value in the Maximum Grammar Staleness field, as described above.

Maximum Grammar Staleness

The maximum amount of time beyond the normal expiration time of an utterance that the application server will accept.

The application adds this value to the value in the Maximum Grammar Cache Age field and compares it to the current age of the utterance plus the value in the Minimum Grammar Freshness Time field, as described in the Maximum Grammar Cache Age field.

VAD Parameters group

Field

Description

VAD Mode

The Voice Activity Detection mode.

VAD Mode determines whether local VAD, the VAD of the cloud speech provider, or a combination of both VADs are used.

The VAD mode values are the following:

  • <None> - AEP local VAD is enabled and uses the default GMM VAD or the system-wide VAD type specified in mppconfig.xml.

  • Disabled - AEP local VAD is disabled and the audio stream is sent immediately to the cloud provider.

  • Enabled - AEP local VAD is enabled and uses the selected VAD type algorithm to detect speech energy. Once speech energy is detected, AEP sends the audio stream to the cloud provider.

  • Hybrid - AEP local VAD is enabled for the initial response in every call but is disabled for all other utterances for the rest of the call. Therefore, the local VAD is used first, and then the cloud provider VAD is used for the rest of the call.

Description

Transcription section
Note:

The Change Transcription Privacy feature controls the DTMF Data, Prompt Data, TTS Data , and Speech Data fields on the applications web page. The Transcription fields are enabled when a user logs in with the Privacy Manager role. The Transcription fields are disabled when a user does not have the Privacy Manager role. To assign the Privacy Manager role, you can create a new user account by navigating to the User Management > Users page and adding a new user. You can assign the Privacy Manager role to this new account. When you sign in with the Privacy Manager user role, the Transcription fields are enabled.

Transcription Enabled

Whether Experience Portal creates a transcription log for each call handled by the application.

Transcription Sample Rate

The percentage of times that this application will generate a transcription log when it runs.

For example, if this field is set to 25%, then the application will generate a transcription log once out of every four times it runs.

You can use this field to reduce application logging if your Experience Portal system is running under a heavy load.

Performance Trace

Whether Experience Portal creates a performance trace log for each call handled by the application that has an associated transcription log.

Field

Description

Support Remote DTMF Processing

Whether the ASR server or the MPP server performs Dual-tone multi-frequency (DTMF) processing.

The options are:

  • Yes: The ASR server performs DTMF processing.

  • No: The MPP server performs DTMF processing.

DTMF Type Ahead Enabled

Whether the application supports DTMF type ahead.

DTMF type ahead feature allows a user to provide DTMF input when the prompt is being presented and thereby skip the prompt.

The options are:

  • Yes: The application supports DTMF type ahead.

  • No: The application does not support DTMF type ahead.

Note:

This field is enabled only when the Support Remote DTMF Processing field is set to No.

Converse-On

Whether the application is invoked by an Avaya Call Center system using the converse-on vector command.

The converse-on vector command makes it possible for the Call Center vector program to call and access a speech application on the Experience Portal system. When it does so, the vector program on the Call Center server makes it possible to send data in the form of DTMF tones. This option tells Experience Portal to listen for these DTMF tones before starting the VoiceXML application.

Network Media Service

Whether this application uses the “voice dialog” Network Media Service for passing the application starting URI as part of the SIP invitation.

Note:

For more information, see RFC 4240 at http://www.rfc-archive.org/getrfc.php?rfc=4240.

Early Media

Whether the administrator has enabled early media for the application.

Experience Portal applications interact with callers before the incoming call is answered. For application types that include voice such as VoiceXML, CCXML, or VoiceXML/CCXML, the administrator can enable or disable early media on the EPM web interface. Early Media informs CCXML applications that the application is to be launched before the call is answered. The default CCXML application will launch the application without accepting the call when this flag is set.

Sync FROM and PAI Headers

If a caller A calls into an application or agent and the application or agent needs to place an outbound call for call transfer, then on the deskphone caller ID, the system displays as if the call is originating from caller A instead of displaying the application or agent phone number.

The options are:

  • Yes: Displays the call originating instead of the application or agent phone number.

  • No: Displays the application or agent phone number.

The default is No.

Dialog URL Pattern

A regular expression used to verify the starting URI form the SIP invitation. This is a security parameter used to verity the URI is “trusted.” If it is blank, then any URI will be accepted.

VoiceXML Event Handler

The VoiceXML event handler to use for this application.

CCXML Event Handler

The CCXML event handler to use for this application.

Generate UCID

The Universal Call Identifier (UCID) is an Avaya-proprietary call identifier used to help correlate call records between different systems.

Inbound Calls:

If the Avaya Communication Manager (CM) passes a UCID to Experience Portal, Experience Portal always uses that UCID regardless of the setting in this field. If, however, CM does not pass a UCID, the Experience Portal MPP server can generate one for the call.

The options are:

  • Yes: If the CM does not pass a UCID to Experience Portal, the MPP server generates a UCID.

  • No: The MPP does not generate a UCID.

Transfers & Outbound Calls:

The options are:

  • Yes: For blind and supervised transfers using the <redirect> CCXML tag, the MPP uses the same UCID as the call being transferred. For Bridge and Outcalls , MPP will generate a new UCID.

  • No: The MPP does not generate a UCID.

Operation Mode

The SIP header for each call can contain User-to-User Interface (UUI) information that the switch can either pass on as a single block or attempt to parse so that the information can be acted on. This field determines how Experience Portal treats the UUI data.

The options are:

  • Service Provider: Experience Portal passes the UUI data as a single block to the application without making any attempt to interpret data.

    If you select this option, the application must handle the UUI data on its own.

  • Shared UUI: Experience Portal takes the UUI data and parses it into an array of IDs and their corresponding values. It then passes the application both the fully encoded UUI data and the parsed array with only the values still encoded.

    If you select this option, the UUI data must conform to the Avaya UUI specifications described in User-to-User Interface (UUI) data passed in SIP headers.

Transport UCID in Shared Mode

If Operation Mode is set to Shared UUI and Generate UCID is set to Yes, this field determines whether Experience Portal encodes the Experience Portal-generated UCID and adds it to the UUI data for all outbound calls.

Maximum UUI Length

The maximum length of the UUI data that can be passed in the SIP header. If this length is exceeded and Experience Portal generated a UCID for the call, the UCID is removed from the UUI data. If the result still exceeds this value, or if the UCID was passed to Experience Portal by the application, Experience Portal does not send any UUI data. Instead, it leaves the entire field blank because it has no way to determine what can be left out.

Fax Detection Enabled

Whether this application should detect whether the inbound number is a fax machine.

The options are:

  • Yes: The application should attempt to identify whether the caller is a fax machine and route any fax machine calls to the telephone number specified in Fax Phone Number.

  • No: The application should not attempt to identify whether the caller is a fax machine.

Fax Phone Number

If Fax Detection Enable is set to Yes, this is the telephone number or URI to which fax machines calls should be routed.

Video Enabled

Whether the support for the video server is enabled or disabled.

The options are:
  • Yes: Enables the video server for a particular application.

  • No: Disables the video server for a particular application.

Video Screen Format

The selected video screen format.

The options are:
  • CIF: Common Intermediate Format. The screen resolution for CIF is 352x288 pixels.

  • QCIF: Quarter CIF. The screen resolution for QCIF is 176x144 pixels.

  • SQCIF: Sub-Quarter CIF. The screen resolution for SQCIF is 128x96 pixels.

Video Minimum Picture Interval

Video Minimum Picture Interval (MPI) is the time interval used to define the frame rate. MPI uses the CIF, QCIF, and SQCIF formats.

For CIF, QCIF and SQCIF, if the value is zero, the screen format is disabled otherwise the frame rate is defined by (29.97/MPI). For example: for value 1 = 30 FPS, for 2 = 15 FPS, and so on.
