Text-to-Speech (TTS) in Webex Contact Center
In this articleThis article provides information about the in-built Text-to-Speech (TTS) capability in the Webex Contact Center solution that seamlessly converts text into synthesized audio.
Overview
Webex Contact Center offers in-built Text-to-Speech (TTS) capability for customers. TTS automatically converts any written text into speech or synthesized audio to provide Interactive Voice Response (IVR) service to customers. TTS service includes a predefined set of neural voices and language options that you can configure in the IVR application to build call flows.
Note: Existing customers on the Webex Contact Center Next Generation Voice Media Platform can view both Cisco TTS and Google TTS connectors in the Prompt settings of IVR activities, such as Play Message, Menu, and Collect Digits in the Flow Designer. Refer to the Webex Contact Center Seup and Administration Guide for configuration details.
