Variable Prompt Item

Variable prompt items are variables used for prompt. Depending on the type of a variable, a variable prompt item can be either a TTS prompt item or an audio prompt item. For example, if a variable contains the caller phone number, then it is a TTS prompt item; if it represents an audio file name, such as the recording of the caller voice message, then it is an audio prompt item.

Example

A variable is usually used to hold information from some actions. In the 24-Hour Information Hotline sample, action get_info_24 is executed and the return values are: get_info_24.content and get_info_24.lastUpdated. To play the information to the caller, these two variables are use in the prompt as shown below. (Prompt items shown with [] are variable prompt items)

Since actions are executed before any prompt is played to the caller, action return variables, such as get_info_24, can be used in prompt of the same element.

Create or Edit a Variable Prompt Item

Select the variable radio button, then select the variable name from the dropdown list. If it is an action return variable (get_info_24), then specify the return parameter name (content) also.

The default variable is Text-to-Speech.
