The article explains how to create a talking text feature using Twilio, .NET Core, Cognitive Services and Azure Storage. The project involves sending an incoming SMS to the application, which converts it into speech using Microsoft's Speech Service API, stores the audio in Azure Blob Storage, and plays it back over a phone call initiated by Twilio. The code is written in C# and uses various NuGet packages, including Twilio and Cognitive Services. To test the project, ngrok can be used to create a public-facing URL that maps to the local application. Once set up, users can send themselves a text message, which triggers the talking text feature, allowing them to receive a phone call with the audio playing back their message.
