Create a Real-Time Voice Assistant on Microsoft Community Hub
We’re excited to share the latest news on Azure Communication Services’ bidirectional audio streaming APIs! These APIs open up new possibilities for interactive voice-based AI experiences, as showcased during Satya Nadella’s recent Ignite keynote. With these tools, you can bring that same level of engagement to your own projects.
By connecting voice agents in real-time with callers, the bidirectional audio streaming API elevates the quality of voice-driven interactions. It’s all about creating natural-sounding conversations that flow seamlessly between AI agents and users. Prompt responses are key to keeping the chat on track by avoiding awkward delays.
Gone are the days of juggling various models for transcription, inference, and text-to-speech conversion to build a voice bot. Thanks to Azure’s bi-directional audio streaming APIs and GPT-4o Realtime API, developers can now tap into live audio from calls and process it with minimal latency. This allows for near-instantaneous back-and-forth communication to enhance user experiences.
Ready to build your very own real-time voice agent? Dive into our QuickStart guide, but make sure you have the necessary prerequisites in place: an active Azure Subscription, Azure Communication Resource, an Azure Communication Services Phone Number, Azure Dev Tunnels CLI, Azure OpenAI Resource, Azure OpenAI Service Model, and a solid .NET development environment.
Once everything is set up, follow the steps in the guide, including hosting your Azure dev tunnel and configuring your API keys and endpoints. After running the application, register an Event Grid Webhook for the IncomingCall Event and start testing the app by calling your Azure Communication Services number! You’ll be able to engage with the voice agent, see live transcriptions, and get a feel for its capabilities.
With the app running smoothly, take a closer look at the code snippet provided in the QuickStart guide to understand how the endpoint handles inbound calls. This is where the magic happens as the system processes incoming events, validates subscriptions, and sets up callbacks for seamless bidirectional audio streaming.
So go ahead, explore the possibilities of Azure Communication Services’ bidirectional audio streaming APIs and create your own voice-driven AI experience today! The future of interactive voice agents is here, and it’s waiting to be built by you.
