Prolog information
Metadata
Keywords:
Use this page to view an existing Text-to-Speech (TTS) server.

General Section

Field
Description
Zone
The name of the zone where the TTS server is configured.
Name
The unique identifier for this TTS server on the Experience Portal system.
Enable
Whether this TTS server is available for use by the Experience Portal system.
Engine Type
The type of TTS software engine the server uses.
Network Address
The network address, or location, of the TTS server you want to use.
Base Port
The port number on the TTS server to which requests for TTS services are to be sent.
Total Number of Licensed TTS Resources
The total number of licensed TTS resources that is used by the Experience Portal system.
Experience Portal uses this information to determine the total number of TTS resources available to the Experience Portal system.
New Connection per Session
Whether Experience Portal establishes a new connection on the TTS server for each call session.
Voices
Displays the selected voices that the TTS server is configured to use.
Note:
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.
Listed Directory Number (LDN)
If this field appears, Avaya Services is maintaining this Experience Portal system and an Avaya Services representative has specified this LDN for this server.

MRCP Section

Field
Description
Ping Interval
When a speech application requires TTS rendering, the MPP establishes a connection to the TTS server at the beginning of a session. Experience Portal sends periodic "heartbeat" messages to the TTS server to make sure the connection is not terminated prematurely.
This field specifies the number of seconds the Experience Portal system waits between the heartbeat messages.
Response Timeout
An integer value specifying the number of seconds to wait for the TTS server to respond to a request for TTS before timing out.
Protocol
The MRCP protocol used for allocating the media processing server resources (TTS).
The options are:
  • MRCP V1
  • MRCP V2
RTSP URL
The URL of the Real-Time Streaming Protocol (RTSP) server. The RTSP server is the network remote control for the Experience Portal multimedia servers.
Note:
This field is displayed only if the Protocol field is set to MRCP V1 while adding the TTS server.
Enable Session XML
Displays when you select the MRCP V2 option in the Protocol field. Parameters specified in the session.xml file supersede vendor-specific parameters specified on the Applications webpage.
The options are:
  • Yes: Session.xml specified for each voice application is sent to the speech server. If Session.xml is not specified for the voice application, the system generates and sends a session.xml file that consists of an organization and application name.
  • No: Session.xml is not sent to the speech server for any voice application.
Transport Protocol
This field is only shown when you select the MRCP V2 protocol under the MRCP section.
The transport protocol used for transporting the real-time data.
The options are:
  • TLS
  • TCP
Listener Port
This field is only shown when you select the MRCP V2 protocol under the MRCP section. The default is 5060 if you select MRCPV2 (TCP) protocol and the value changes to 5061 for MRCPV2 (TLS) protocol.

Configured SRTP List Section

This group displays any SRTP configurations defined for the connection.
Note:
This group only appears if the Transport Protocol field is set to TLS.
Field
Description
Configured SRTP List box
Displays the SRTP configurations for this connection.
