Parameter Description

• Node Name: name of a node.
• Description: details of a node.
• Operation: The options are Initiate, TTS, and Call Ending.
  Figure 1 Setting Operation for the Avatar Reply diagram element
  
  • Initiate: A session with the virtual human service is initiated. You need to specify the virtual human to be used.
  • TTS: The configured text is provided for the virtual human service for video synthesis and playback. Variables can be added to the reply text, and the virtual human service dynamically plays a voice based on the return values of the variables.
  • Call Ending: The session with the virtual human service is ended.
• Avatar Image: This parameter is displayed when Operation is set to Initiate. Select a virtual human configured on the Configuration Center > Chatbot Management > Flow Configuration > Resource > Virtual Human page.

• Reply Variable: This parameter is displayed when Operation is set to TTS. Enter the text variable to be used by the virtual human to reply.
  Figure 3 Selecting TTS
  
  1. Reply Template: This parameter is displayed when Operation is set to TTS. Select a template whose Type is TTS under Configuration Center > Chatbot Management > Flow Configuration > Resource > Resource Template.
  2. Reply Variable: This parameter is displayed when Operation is set to TTS. Set Reply Variable to a variable of the Character type.
  3. Reply Resource: This parameter is displayed when Operation is set to TTS. Select a text resource whose Status is Approved under Configuration Center > Resource Management > Audio and Video.
• Reply Mode: This parameter is mandatory. The options are as follows:
  • Playback only: Only the voice or video is played, and customer input does not need to be received. Generally, this option is selected for static voice playback.
  • Interruption recognition: The customer needs to answer by voice. Generally, this option is selected for replying to text.
  • Interruption by key presses: The keys pressed by the customer need to be obtained. If Reply Mode of the Robot Reply diagram element is set to Interruption by key presses and the key interaction result needs to be obtained, the Robot Reply diagram element cannot be directly connected to the Call Ending diagram element, and the Key Recognition and Semantic Recognition diagram elements cannot be directly connected before the Call Ending diagram element.
  • Recognition and key presses: Both voice and key information can be received. The information received first is used for matching.
  • Recognition after playback: The system starts to identify the voice or video only after the voice or video is played. If a customer speaks during the playback, the system does not receive the voice.
  • Recognition and key presses after playback: The system starts to identify the voice or video and collect digits only after the voice or video is played. If a customer speaks or presses a key during the playback, no information can be received. If a customer speaks or presses a key after the playback, the information that is received first is used for matching.
  • No interruption after digit collection: Keys can be pressed when the voice or video is played, but the playback is not interrupted.
  • Custom Variable Value: whether voice playback can be interrupted. If voice playback can be interrupted, set Minimum Voice Playing Duration.

    String true -- Voice playback can be interrupted during recognition, and the minimum voice playback duration can be passed.

    String false -- Recognition is performed after voice playback.

• Timeout Interval: timeout period, in seconds. If this parameter is not set, the default value 15 is used. If the duration exceeds the value of this parameter, the system determines that timeout occurs. The value range of this parameter varies with vendors. Currently, the maximum value is 180.
  • If Reply Mode is set to Recognition after playback, the duration starts from the time when the TTS voice playback ends to the time when the recognition stops.
  • If Reply Mode is set to Interruption by key presses or Interruption recognition, the duration starts from the time when the voice playback ends. For example, if a customer does not speak after the TTS voice playback ends, the robot goes to the next diagram element when the timeout period ends.
  • If Reply Mode is set to Playback only, the timeout period does not take effect.
  

  Pay attention to the setting of the timeout period in the following scenarios: long TTS voice playback, many keys (such as an ID card) to be pressed by a customer, and many opinions to be said by a customer. When Reply Mode is set to Interruption by key presses or Interruption recognition, if the timeout period is short, the recognition may start before the voice playback ends, or the recognition may end before the customer completes key pressing. If the timeout period is long, there may be a long-time silence after the customer completes key pressing, and a timeout notification is displayed after a long time.

• ASR Advanced Settings: The options are Enable and Disable. The default value is Disable.
  • Recognition Type: The option is Common. The default value is Common. This parameter is configurable when ASR Advanced Settings is set to Enable.
  • Subscriber Silence Timeout Interval: The default value is 100, in seconds. The value ranges from 0 to 32000. This parameter is configurable when ASR Advanced Settings is set to Enable.
  • Recognition Timeout Interval: The default value is 200, in seconds. The value ranges from 0 to 600. This parameter is configurable when ASR Advanced Settings is set to Enable.
  • Subscriber Pause Timeout Interval: The default value is 500, in milliseconds. The value ranges from 300 to 2000. This parameter is configurable when ASR Advanced Settings is set to Enable.
  • ASR Extended Parameter: Enter the data required by the ASR business on the IVR side, for example, the vendor information. The value is returned to the IVR system using the vendor parameter of the dialog interface.
• TTS Advanced Settings: The options are Enable and Disable. The default value is Disable.
