-Azure AI-powered Call Automation API actions are now generally available for developers who want to create enhanced calling workflows using Azure AI Speech-to-Text, Text-to-Speech and other language understanding engines. These actions allow developers to play dynamic audio prompts and recognize voice input from callers, enabling natural conversational experiences and more efficient task handling. Developers can use these actions with any of the four major SDKs - .NET, Java, JavaScript and Python - and integrate them with their Azure Open AI solutions to create virtual assistants that go beyond simple IVRs. You can learn more about this release and its capabilities from the Microsoft Ignite 2023 announcements blog and on-demand session.
