Converting Speech to Text in Flutter Applications
Blog post from Deepgram
In this tutorial, learn how to transcribe messages in real-time using Flutter applications and Deepgram's Speech Recognition API. The audio is converted into data and live-streamed over WebSocket to Deepgram's servers, which then transcribe the audio and return it in JSON format back through the WebSocket. To set up this application, you will need a Deepgram API Key and follow instructions for installing Flutter onto your machine. The tutorial guides you through adding device-specific permissions, creating a user interface with three components (text area, start button, stop button), handling text state, installing dependencies, and handling audio input. Finally, test the application by running flutter run on your mobile device.
