RealSub puts live subtitles on anything your Windows PC plays: videos without a subtitle track, live streams, games, lectures and podcasts. Speech is recognized on your own machine, so audio never leaves your PC. Caption the whole system or just one app. Recognizes Japanese, English and Chinese. The free base app gives complete live transcription; the Full Version DLC adds translation, history and SRT / TXT / MP3 export. 7-day full trial. Available on Steam.
