• Voice File: The system filters approved voice files, TTS files, or video files based on the selected voice type, and displays the files in the drop-down list box. You can click and select a required file.
• Received Digits: This area displays parameters used to receive the external input.
  • Max. number of digits received: maximum number of input digits that can be received. The default value is 24. If this parameter is set and the number of digits entered by a customer reaches the maximum value, the system automatically goes to the next step.
  • Select a parameter to save the input of the user: parameter for carrying information required by the diagram element. Click the text box. In the displayed dialog box, select a global variable or flow variable as required, for example, FLOW.IDNumber. The system saves the information entered by the customer by using a variable of the string type. Therefore, you can select only a variable of the string type.
  • Waiting Time for Digit Collection: time to wait for the digit input. If the time when a customer stops the input exceeds that specified by Waiting Time for Digit Collection, the system records a failure, automatically executes Digit collection timed out, and continues to wait for the digit input.
  • Max. Failure Times: maximum number of input attempts that are allowed. When an error occurs during digit collection, the system records a failure, automatically executes Digit collection failure, and continues to wait for the digit input.
  • Timeout interval for digit collection: Timeout interval for pressing a key. For example, if this parameter is set to 2 seconds, the flow proceeds when the key pressing interval exceeds 2 seconds, even though the number of collected digits does not reach the specified value.
• Advanced Settings: You can click Advanced Settings + to expand this area and click Close to collapse this area.
  • Digit collection failure: You can click to enable the capability of playing a voice upon a digit collection error. Then, if digits fail to be collected before the number of a customer's input attempts reaches the maximum specified by Max. Failure Times, the system plays a voice to notify the customer.
  • Digit collection timed out: You can click to enable the capability of playing a voice upon digit collection timeout. Then, if digits fail to be collected after the wait time reaches the maximum specified by Waiting Time for Digit Collection, the system plays a voice to notify the customer.

• By default, Digit collection failure and Digit collection timed out are disabled in the Advanced Settings area. If the capabilities are disabled, the system replays the voice configured for the voice playback and digit collection diagram element upon a failure.
• When the number of a customer's input attempts reaches the maximum specified by Max. Failure Times, the system executes the common failure exit.

Typical Application Scenarios

The system needs to interact with a customer and continue with the subsequent flow based on the input of the customer. For example, the system can handle a business only after a customer enters an identification number.
