Are you replacing your Olympus DS-4000 or DS-3000?  Call us at 888-462-4346 or email us regarding its buy-back or trade-in value.  We will consider a DS4000 or DS3000 in any condition -- new, used and working or damaged.

Overview    (This product is sometimes listed as: Olympus DS 4000 or DS-4000 or DS4000 and has been replaced in the Olympus product line by the Olympus DS 5000 or DS-5000 or DS5000.)

This recorder is no longer being manufactured as of 2008 - a few factory-refurbished units starting to become available and the very occasional new unit is sometimes located.  This product has been replaced in Olympus product line by the Olympus DS-5000.   If you are using the DS-4000 already, you may want additional DS-4000 units, but consider transitioning to the DS-5000, which has a DS-4000 compatibility mode plus higher fidelity and many new features.  If you are selecting a brand new digital recorder platform, definitely start with the Olympus DS-5000.

The recorder has a built-in microphone and speaker, as well as auxiliary jacks for an external mic and headset (sold separately).  If you need to use the recorder in a noisy environment or want to improve accuracy, any microphone can be plugged into the microphone jack.   Olympus also makes available the ME-12 microphone (see below).


Speech Recognition Setup/Usage: 
Users must create a recorder-specific voice file or a second input source (new capability in NaturallySpeaking V8).  

Installation Overview:   If we are not performing your install for you, be sure to load your Olympus software and service packs before connecting your recorder.   See our NaturallySpeaking support web page for a link to the Olympus download page. (The Olympus link is at the bottom of this page.)

NaturallySpeaking User Setup:  To set up your NaturallySpeaking recorder user file or second input source for your existing NaturallySpeaking user file, you will read one of several NaturallySpeaking training scripts into your recorder, upload the audio and then allow the NaturallySpeaking new user routine to process the audio file.

Usage Workflow:   Dictators can choose whether to manage the transcription of their dictation themselves or work with a support person/team.  The only step dictators have to do themselves is dictate.  The remaining steps can be done by others.   To use NaturallySpeaking to transcribe your dictation, the recorder will need to be either docked or connected to your PC via the USB cable OR the xD memory card can be read through a memory card reader.  The Olympus DSS Player Pro software, if properly installed, will automatically start and the audio will upload.  (You can set options in the DSS Player to perform various steps for you automatically.)  You will select one or more audio files.   The DSS Player Pro (since R4.2) has a red dragon button that you can click to automatically send the selected audio to NaturallySpeaking for transcription.  You or a support person can proof-read and correct any misrecognitions.  If the dictator is not the correctionist, it is still helpful to feed back constructive criticism to help the dictator hone their dictation style to minimize errors. 

Improving Accuracy Notes:    Just as with a microphone-based NaturallySpeaking user file, accuracy can be increased by selecting the best base vocabulary (Medical, Legal, etc.) and adding to and/or tweaking the vocabulary using the many NaturallySpeaking Vocabulary Tools.  Also, careful correction of misrecognitions using NaturallySpeaking techniques will improve accuracy.  Clear speaking, good enunciation, consistent positioning of the recorder, etc. by the dictator can make a huge difference.  Also, consider an external microphone to suppress background noise.
