This tutorial demonstrates how to add speech recognition capabilities to a React and Node.js project using Deepgram's Automatic Speech Recognition (ASR) technology. The author provides step-by-step instructions on adding the speaking feature, creating a server connection, and connecting the WebSocket to the front-end. The final result is an application that allows users to speak affirmations aloud, transcribes them using Deepgram's Node SDK, and displays the transcription on the screen. The code for this project can be found in the provided GitHub repository.
