Description

A dictation machine is a sound recording device most commonly used to record speech for later playback or to be typed into print. It includes digital voice recorders and tape recorders.
The Ediphone was one of two competing wax cylinder phonograph systems for voice dictation, the other being the Dictaphone system. The use of cylinders for voice recording pre-dated their use for music, although it wasn’t until 1888 that Edison switched from tinfoil to wax cylinders in response to the rival Graphophone system introduced in 1887 (that later became the Dictaphone system).
