Youshow Interpreter listens to speech as it happens, recognises it and shows both the original words and a translation on screen. It is designed for long lectures and meetings, as well as face-to-face conversations while travelling.
Sessions are saved so you can review them later, and you can export bilingual SRT subtitle files, which helps with video captioning. It runs on the web, iOS, Android, macOS and Windows. The interface is mainly in Chinese.
