Dictaphone

Dictaphone was an American company, a producer of dictation machines—sound recording devices most commonly used to record speech for later playback or to be typed into print. The name "Dictaphone" is a trademark, but in some places it has also become a common way to refer to all such devices, and is used as a genericized trademark. At present, Dictaphone is a division of Boston-based Nuance Communications.
