Speech Engines for Anywhere365

Introduction

There are multiple ​TextToSpeech engines that are currently available, only one SpeechProvider can be selected per UCCUCC stands for Unified Contact Center and consists of a queue that can be handled by Agents Each Contact Center has its own settings, interactive voice response questions and Agent with specific skills. Agents can be member of, or sign up to, one or more Contact Centers..

Each SpeechProvider can be configured with a SpeechPreferredVoiceName,

When a speech provider can't initialize or is misconfigured the MicrosoftSpeechSythesizer will be used as fallback.
