![]() We toggle the recording state and implement an if-else-statement for the two states. This function will be executed whenever the user clicks on the button to start or stop the recording. Then we need to create only one function to handle all the logic. ![]() required dom elementsĬonst buttonEl = document.getElementById('button') Ĭonst messageEl = document.getElementById('message') Ĭonst titleEl = document.getElementById('real-time-title') Additionally, we make global variables to store the recorder, the WebSocket, and the recording state. Next, create the index.js and access the DOM elements of the corresponding HTML file. Step 2: Set up the client with a WebSocket connection in JavaScript Try AssemblyAI's new real-time transcription endpoint! To use a microphone, we embed RecordRTC, a JavaScript library for audio and video recording.Īdditionally, we embed index.js, which will be the JavaScript file that handles the frontend part. You can get one here and get started for free: Get a free API Key Step 1: Set up the HTML code and microphone recorderĬreate a file index.html and add some HTML elements to display the text. One of the easiest to use APIs to integrate is AssemblyAI, which offers not only a traditional speech transcription service for audio files but also a real-time speech recognition endpoint that streams transcripts back to you over WebSockets within a few hundred milliseconds.īefore getting started, we need to get a working API key. ![]() The easiest solution is a Speech-to-Text API, which can be accessed with a simple HTTP client in every programming language. Real-Time Voice-To-Text in JavaScript With AssemblyAI This article shows how Real-Time Speech Recognition from a microphone recording can be integrated into your JavaScript application in only a few lines of code. ![]()
