Introduction:
While preparing to review the new Olympus DS-7000 and DS-3500 (little brother
pushbutton version of the DS-7000) digital recorders, it occurred to me that the most
effective way to do so would be in the context of the other top ratedtranscription digital
recorders.
Note that when you purchase a digital recorder from KnowBrainer Inc., you additionally
receive a hard copy of our exclusive Digital Recorder User Guide which includespictorial
step-by-step instructions on how to create a digital recorder profile, setting up your
recorder, transcribing your recordings and setting up the Dragon AutoTranscribe Folder
Agent for effortlessbatch file transcription of multiple recordings with no end-user
intervention other than effortlessly connecting your recorder to a USB port. Note that
this feature is only available in Dragon Pro, Medical, and Legal.

Evolution of Speech Recognition Recorders
When we first began using DragonDictate speech recognition software in the 1980’s it
seemed to be incredibly impressive technology. Never minding the very deliberate pause
after each and every word, we waited with baited breath to see another (hopefully

correct) word miraculously appear on our somewhat blurry little screens.It was fun! It
was frustrating!
In 1996, NaturallySpeaking continuous speech recognition was released. Withthe
emergence of this new technology, we had a viable tool for professional as well as
personal use. That being the case, we needed something better than the usual classic
cassette recorder to better utilize this increasingly more sophisticated software and
several manufacturers responded. The 1st digital recorder we were able to test was
called the VoiceIt which was manufactured directly for DragonSystems (previous owner
of NaturallySpeaking). Olympus released the DS-1000 on the heels of the VoiceIt and
followed up a year later with the DS-2000. We found the DS-2000 to befair but the
VoiceIt and DS-1000 fell below our level of acceptability. Eventually, Olympus took a
decisive recorder lead when they introduced what we considered to be the 1st serious
professional recorder, the DS-3000 and the consumer grade DS-330. Both units featured
the new Olympus patented DSS algorithms which were designed for speech recognition
but limited to 5 kHz frequency response. Olympus eventually improved on their
technology by releasing the DS2 algorithms with an 8 kHz frequency response. Oddly
enough, the 1st digital recorder to hit the market featuring the new DS2 algorithms was
the Philips 9600. Although Philips licensed the DS2 technology from Olympus, Olympus
didn't get around to releasing the DS-5000, featuring DS2 algorithms, until 9 months
later. A few years later, Grundig introduced their Digta 7 series and on April 17, 2012,
Olympus released their 4th generation professional digital recorder, the DS-7000 and a
second-generation DS-3400, relabeled the DS-3500 (same as the DS-7000 but without
the cradle, or slider control).
There are literally several hundred digital recorder choices on the market, including
many that are recommended by Nuance. Although most Nuance recommendations work
okay for consumer use, AllNuance recorder recommendationsshould be taken with a
healthy grain of salt. For example, Nuance gives the Sony ICD MX20 (which comes
bundled with some versions of NaturallySpeaking) a Dragon rating of 6 but we consider
it to be more of a consumer grade toy than a professional dictation tool. By contrast, the
superior Olympus DS-5000 scored a 4 Dragon rating and the Philips 9600 scored 3
Dragons.
If a digital recorder and speech recognition play a major role in your workflow, we can
only recommend “non-jack of all trades recorders” that are designed exclusively for
transcription and utilize DS2 algorithms which reduce the error rate and include a
lossless 12 to 1 compression ratio for quick and securefiletransfer. You might think that
a stereo 96 bit HD quality digital recorder would be excellent for speech recognition use
but the recordings are huge (not easy to e-mail or FTP) and as amazing as it sounds,

3. 3
can produce as much as twice as many errors which is simply not efficient. Additionally,
the controls on these types of recorders are simply not designed for dictation. HD digital
recorders are intended for recording live music and don't feature professional
transcription amenities like cue/review, seamless glitchless punch in, double speed
playback (without the Mickey Mouse effect), main functions located under a convenient
slider control, along with other standard transcription features. Professional recorders
also include specialized transcription assisting applications for encrypting recordings and
secure FTP and e-mail transfers along with NaturallySpeaking support. If you are a
physician or an attorney handling sensitive materials, only professional digital recorders,
such as those in this review, include 128/256 bit AES encryption. If you are a physician,
don't even think about using most Nuance recommendations because they are not
HIPPA compliant.
This review only covers professional transcription digital recorders that utilize the
patented OlympusDS2 algorithms. We are not the only ones who tested and found DS2
algorithms to bemore accurate for speech recognition transcription. Apparently both
Philips and Grundig also agree because both companies are willing to pay Olympus a
royalty to use their patented DS2 algorithms in their top-of-the-line recorders. This is
also why only carry digital recordersthat feature DS2 algorithms on our website.
A professional digital recorder just might be what you need if:
You realize that your Siri speech-enabled smart phone app doesn't live up to the
hype.
You don't have time to wait for your computer to boot up.
You don't have the space or budget for a mobile computer.
You need to make verbal notes on the go that you can transcribe at a more
convenient time.
You need to quickly e-mail or FTP recordings for someone else to transcribe.
You require 128/256 bit AES encryption for security reasons.
You need to be able to make quick noiseless edits/changes (punch-in) to your
digital recordings without introducing an audible click.
The following is a general consensus of 5 speech recognition experts on the pros and
cons of what we believe to be the top 3 speech recognition professional digital
recorders, followed by our ratings.

Pros& Cons
Olympus DS-7000 Pros:
MSRP Map Price: $499
2 Year Warranty
The only recorder that can utilize a 32 GB SDHC card which can record over 2500
hours (that’s 105 consecutive 24-hour days) at the highest quality setting.
Impressive largest color BACKLIT 2" HD screen. Other recorders are nowhere near
as easy to view under varying light conditions and most recorders do not include a
backlit screen.
Largest Microphone element of any professional transcription recorder, including
anti-vibration feature and extended conference style recording range.
File transfer speed is nearly double that of the competition.
Metal housing includes secondary exoskeleton for additional strength when the
unit lands on 1 of its corners.
The best tactile feel pushbuttons of any recorder.
3 end-user programmable buttons.
Improved Ver. 6 Dictation Module application includes far more features than the
competition along with impressive support for NaturallySpeaking right down to
Roaming user profile support and even an option to automatically launch
NaturallySpeaking and transcribe recordings in the background (a 1st
).
A choice of Real Time or Background NaturallySpeaking transcription.
Programmable slider control.
21 hour lithium fast rechargeable battery pack.
Optional password lock protection.
256 AES Encryption (HIPPA compliant)
Workgroup and Server install options.
Olympus DS-7000 Cons:
Microphone and headphone jack moved to the side of the unit which we found to
be clumsier than other units (including the previous Olympus recorders) which
locate the microphone and headphone jack conveniently at the top of recorder.
$50 more than the Philips 9600.
Although the battery pack can handle up to 21 hours of continuous dictation, we
prefer the DS-5000 design which would allow you to substitute AAA batteries in
the event that the battery pack went dead.
Longer boot time than the previous DS-5000 model.

5. 5
Smaller playback speaker that the competition.
Plastic power on/off switch looks flimsy.
Philips 9600Pros:
MSRP Map Price: $449
1 Year Warranty
Includes 3 recording modes as opposed the 2 offered by the DS-7000.
Includes around the world voltage adapters for charging in any country.
Best playback speaker.
Philips 9600Cons:
Limited to the included 2 Gb memory card but doesn’t include a separate built-in 2
Gb micro SD card like the DS-7000 and Digta 7.
Slider controls a bit stiff when compared to the competition.
Notably dated technology when compared to the modern amenities of the other 2
units.
Proprietary rechargeable AAA batteries only last approximately 9 hours as
compared to approximately 25 hours in the other 2 units.
Buttons are a bit mushy
GrundigDigta 7Pros:
MSRP Map Price: $524 - $550
2 Year Warranty
Only Pro speech recognition transcription recorder with dual microphone elements.
Only transcription recorder that includes a WAV file option for recording live music
in HD.
Includes over a dozen formating options.
Includes anaccelerometer that will automatically turn off a recording when it
senses it's been dropped 3 feet.
Direct transfer of dictation via smartphones (limited to 704 Bluetooth model).
Slider control includes “touch pin” which lets the end-user operate the unit by feel.
128/256 bit encryption for security and hippo compliance.
Works with included battery pack or optional AAA batteries.
Programmable slider control.

6. 6
Includes docking station which can charge an additional 25 hour lithium battery
simultaneously.
Grundig Digta 7Cons:
Requires closing NaturallySpeaking before you can transcribe a recording.
Grundig has pulled its North American support which casts serious doubt on future
support and availability.
Digtation-ID Editor software is fully featured but more difficult to set up than the
competition.
Larger than comparable units
Plastic housing as opposed to the usual metal designs on recorders of this caliber.
Conclusions:
All 3 units were equally accurate at transcribing into NaturallySpeaking Ver. 11. This is
probably not a surprise considering that all 3 units utilize the same Olympus DS2
algorithms. However, only 1 recorder can be #1. Although we factored hardware
features/construction into our scoring, we also factored in pricing, software features,
ease-of-use and manufacturer support.
The Final Score:
1st Place ~ Olympus DS-7000(Click to See)
1st place goes to the Olympus DS-7000 which was probably no surprise considering that
the Olympus DS-5000 (the predecessor) narrowly captured the 1st place position over
the other 2 models. The new DS-7000 design raises the bar by adding serious
NaturallySpeaking support(including Roaming user support and background
transcription), 32 Gb SDHC memory card support, the largest and by far, the easiest to
read color backlit viewscreen, larger control buttons, improved tactile feel, smaller
recessed Erase button (to prevent accidental deletes) and even an improved battery
compartment. Additional manufacturer information available at
www.olympusamerica.com
2nd Place ~ Grundig Digta 7(Click to See)
If our decision had been based on features alone, the Grundig Digta 7 would've been #1
with a number of unique features including touch pin, expanded cradle (which can

7. 7
charge a secondary battery), Bluetooth, stereo HD microphones and an
acceleratormeter which turns off the recorder after it senses a 3 foot drop but we also
had to subtract points for the unusually large size, plastic housing, Digtation-ID Editor
software(that was more difficult to set up) and the requirement to close
NaturallySpeaking before transcribing a file. However, the final nail in the coffin was
Grundig's decision to pull North American support. The Digta 7 is still a safe purchase
and covered by the manufacturer warranty but when a manufacturer decides that they
can't compete and purposefully limits their market, it's usually the beginning of the end.
We are now concerned that the Grundig digital recorder division may cease to exist at
some point in the future. Additional manufacturer information available at
www.grundig.de
3rd Place ~ Philips 9600(Click to See)
When the Philips 9600 was 1st released, it was the proverbial king of the hill but while
Philips rested on its laurels, Olympus and Grundig dropped it down a couple of pegs.
Although this is still a great recorder, the technology is somewhat dated. We found the
buttons to be a little mushy, smallest greyscale viewscreen, 9 hour AAA battery life (the
competitions batteries last 25+ hours) and limited to using a 2 Gb SD memory card
while the other 2 units include 2 Gb built-in micro SD cards along with the option of
adding a much larger memory card. The Philips 9600 is still a great recorder but why
settle for a Taurus when for $50 more, you can get a Cadillac. Additional manufacturer
information available at www.dictation.philips.com

The following is a list of microphones that we consider to be #1 in their microphone
categories we:

8. 8
Best Wireless Microphone = Samson Airline 77
Best Combo Telephone Wireless Microphone = Jabra Pro 9470
Best Handheld USB Microphone = Dictaphone PowerMic II
Best USB TableMike = SpeechWare 3-in-1 / SpeechWare 6-in-1
Best Wired Headset Microphone = Audio-Technica Pro 8HEmW
Best Bluetooth “like” Wireless Microphone = Plantronics Savi 440*
Best Digital Recorder = Olympus DS-7000
Best Speech Recognition Application = NaturallySpeaking 11.5&DMPE
*Bluetooth Note: The Plantronics Savi 440 is not a Bluetooth microphone but comes
seemingly close by emulating the features of a Bluetooth microphone because it
includes a completely wireless headset and wireless receiver. We do not recommend
any Bluetooth microphones for use with Dragon Medical 11, NaturallySpeaking 11,
DragonDictate 2.5 or WSR because Bluetooth microphones are limited to a 4 kHz
frequency response while the previously mentioned speech recognition applications
can process frequencies as high as 11 kHz. Bluetooth also suffers from syncing issues
and that's why we no longer offer or rate Bluetooth microphones.
