Enable Live Captions in Vonage Video Using Symbl.ai

The text discusses adding transcription/closed captioning to a Vonage Video application, leveraging Symbl.ai's web SDK. The goal is to provide accessibility and insights into video calls. To achieve this, the application uses a custom React hook called `useSymblai`, which abstracts away the complexity of opening a WebSocket connection with Symbl.ai. The hook returns captions, the other party's captions, and the name of the speaker. The application also sets up a preferences context to store user information, such as username and conversation ID. The custom hook uses React hooks like `useState` and `useEffect` to manage state and side effects. The text concludes by mentioning additional features provided by Symbl.ai, including sentiment analysis, insights extraction, summary of the call, analytics, and more.
