Build an Interactive Voice Response with Go

This tutorial teaches developers how to build an interactive voice response system using Go and the Vonage Voice API, allowing users to interact with their phone calls through text input and speech output. The developer needs a Vonage API account and a virtual phone number to complete this project. The code handles incoming voice calls by routing them to a webhook endpoint that instructs the user to press any key, records the caller's input, and then responds back to the user with the input they provided.
