What it is

Talk to a voice assistant that can take coffee orders.

What you can make with it

Voice-driven ordering systems, like a simulated café experience with conversations, order updates, and real-time transcription.

How it helps

Save time and effort in building conversational interfaces for customer interactions, showcasing the power of AI.

Real use case example

"A solo developer, Alex, uses Coffee Chat Voice Assistant to create a voice-driven ordering system for a new café she's opening. She sets up the system in 30 minutes, connects it to Azure OpenAI GPT-4o, and tests it with a friend. After a few tweaks, the system is live, and customers can order their favorite coffee with a natural conversation."

If you're new

Pick this up when you want to experiment with voice-driven interfaces and natural conversations for the first time.

If you're senior

Reach for this when you need to integrate voice-driven ordering or live order updates into your existing application, using a pre-built and customizable solution.

Common confusion cleared up

This tool does not provide pre-trained voice assistants; instead, it uses Azure OpenAI GPT-4o as a Realtime API to generate the conversational experience.
