Build a Speech-to-Text App with AssemblyAI on Replit

The AssemblyAI API provides a simple way to implement speech-to-text functionality in various applications. The API offers features like automatic speaker detection, intelligent punctuation, and support for custom vocabulary. It also provides real-time transcription, audio intelligence, and sensitive content moderation. To integrate the API with Next.js, React, and Replit, developers can create three separate API routes: one for uploading files, one for requesting transcription, and one for accessing transcription results. The frontend is built using React, with a simple UI that allows users to select an audio file, transcribe it, and display the results. The app uses Axios to make POST requests to the AssemblyAI API endpoints. Overall, this article demonstrates how developers can use the AssemblyAI API to build speech-to-text applications with ease.
