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 the recording to the VideoSDK platform, transcribing the audio 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 discussed during meetings. The integration process involves setting up a development environment with Flutter SDK, installing VideoSDK, configuring project settings, creating meeting screens, and testing the application.
