VideoSDK's post-call transcription feature allows users to generate detailed transcriptions and summaries of recorded meetings after they have concluded. The process involves recording the meeting, uploading it to the platform, transcribing the audio or video content using advanced speech recognition technology, and making the textual representation available for use in various applications. Benefits include accurate documentation, enhanced accessibility, and easy review and analysis of key points and decisions made during meetings. The integration of this feature into a React application is detailed in the guide, along with instructions on how to fetch the transcription from the VideoSDK dashboard once it's ready.
