VideoSDK's post-call transcription feature allows users to generate detailed transcriptions and summaries of recorded meetings after they have concluded, ensuring important information is not missed and providing a comprehensive record of the conversation. The process involves recording the meeting, uploading it to the platform, processing by VideoSDK's transcription engine, and finally retrieving the textual representation via API. Benefits include accurate documentation, enhanced accessibility, and easy review and analysis. To integrate this feature into a React Native application, developers need to follow specific steps for Android and iOS setup, register services in the root index.js file, create an API request to generate a unique meetingId, wireframe App.js with all components, implement controls, render participant list, handle participants' media, and finally fetch transcriptions from the dashboard.
