Abstract: Small light weight voice recorder is worn by a user as a short term memory aid. It has a single, large, readily accessible control button on its front face. The device has two alternating operating modes, each of which is initiated by actuating the same button in the same way. In a first mode the device records a brief spoken message. In the second mode the message is played back. The device has all solid state components with no moving parts for durability, freedom from maintenance and low battery drain. It is especially useful for those with failing memory who may find the complexities and dexterity requirements of conventional recording devices beyond their capabilities. An alternative embodiment of the invention includes covered, rear mounted controls that are easily accessed and operated for playing back the recorded message at a preset time. This feature is designed to not interfere with the primary function of record and playback by alternate operation of a single button.
