What it is

Talk to a voice assistant that can take coffee orders.

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."

When to use it

•When you want to innovate the customer experience in your cafe or restaurant with a seamless voice-driven ordering system
•When you need to showcase the power of AI for customer interactions in a real-world setting
•When you want to provide a unique and futuristic experience for your customers, setting your business apart from competitors

Ready-to-paste prompt

Ask the voice assistant 'What coffee drinks do you have available?' to see the list of available drinks and demonstrate the natural conversation capabilities

Heads up: Make sure you have an Azure account and have set up the OpenAI GPT-4o Realtime API with the correct API keys and credentials, as this is a prerequisite for the voice assistant to function
