Text to Speech
The Text to Speech (Render TTS) element converts written text into spoken audio, playing it to the caller at a defined point in the IVR flow. Unlike a Play element which requires a pre-recorded audio file, TTS lets you type the message you want the caller to hear directly into the element — including dynamic content pulled from call or lead data.
Connections
| Connection | Description |
|---|---|
| I – Input | The entry point for this element. Connect from the preceding element in your IVR flow. |
| O – Output | The path taken once the text has been spoken to the caller. |
| E – Error | The path taken if the element encounters an error. |
Settings
| Field | Description |
|---|---|
| Name | Give the element a clear name so it is easy to identify within your IVR flow. |
| Description | Optional. Add a note to explain the element's purpose — useful in more complex flows. |
| Agent Can See This | When enabled, agents can transfer a live caller directly to this element via the IVR Transfer option. |
| Supervisor Can See This | When enabled, the element is visible in the IVR Transfer list for users with a Supervisor role. It remains hidden from all other users. |
| Result Code | Assign a result code to this element to track calls that pass through it. |
| Text | Enter the text you want spoken to the caller. This can be static text, dynamic content using double curly brackets {{ }}, or a combination of both. See Dynamic content below for details. |
| Voice | Select the voice to use from the dropdown. By default, two Windows voices are available. Additional voices and languages can be added — contact your account manager for further details. |
Dynamic content
The Text field supports dynamic content, allowing you to include caller or lead-specific information in the spoken message. To use a dynamic field, wrap the field name in double curly braces — for example, {{call.name}}. This is replaced at runtime with the actual value for that call.
Dynamic fields can be used on their own or within a sentence. For example:
This message is for {{call.name}}. If you are {{call.name}}, press 1.
The following fields are commonly used for dynamic content:
| Field | Description |
|---|---|
call.ReferenceID | The reference or account ID for the lead. |
call.Name | The first name or full name of the lead. |
call.Name2 | The last name, company, or other value stored in the Name2 field. |
call.Address | The street address for the lead. |
call.City | The city for the lead. |
call.PostalCode | The postal code for the lead. |
Primary mapped fields to a lead
Formatting content
You can control how certain values — such as dates, times, numbers, and addresses — are spoken by applying a format tag within the double curly braces, separated by a colon. For example: {{call.PostalCode:SpellOut}}.
