The Olympus DM-4 is one of two DM-series digital voice recorders (DM-2, DM-4) released in February 2010. As a step up from the original DM-2, the Olympus DM-4 adds along 4GB of additional memory (8GB total) and Voice Recognition technology so that users can command the device by voice. Plus the DM-4 includes a DAISY player that can play talking-book formats used by the visually impaired. Plus the DM-4 text-to-speech functionality allows a user to hear TXT files instead of having to read them. Like its predecessor, the voice recorder hosts a 2.2” LCD display and built-in stereo microphones for easily recording and editing high-quality audio files. Included also is a long-lasting, 20-hour rechargeable battery, and PC/Mac compatibility.
