Philips LFH 3500 SpeechMike Premium Features and Benefits


Free-Floating and Decoupled Microphone.

By separating the premium microphone from the housing, the new SpeechMike Premium delivers astoundingly clear recordings. The result is a microphone which practically eliminates the sound distortions one typically gets from touch, click, background or housing-born noise.


Optimized Microphone Grille

The hexagonal holes on the new SpeechMike Premium are engineered to be three times more open so that recordings are crystal clear.

When combined with the high quality free-floating microphone the result is a professional device which maximizes such time saving dictation programs like Dragon Medical Practice Edition 4.


Integrated Pop Filter

That popping sound that distracts and can confuse the best speech recognition software is terribly annoying.

So Philips set out to design a hardware fleece inserted above and below the microphone capsule. This fleece rebuffs sound distortions like hiss and pop noise even if you're dictating close into the microphone.


Large Speaker Area

Bigger, Better Sound.

The Philips engineers of the new LFH 3500 doubled the size of the speaker area.

This new feature enables you to play back recordings in high quality, crisp, clean sound right from the SpeechMike Premium.


Optimized Control Panel

You should expect nothing but the best from the people who created the ergonomic zone design: Philips.

Philips tested the SpeechMike Premium with users to ensure that it offers the most comfortable fit for the human hand. The dictation zone keeps thumb movement to a minimum, and button placement guarantees perfect ergonomics that won't fatigue the user. Buttons provide optimum tactile feedback.


Ergonomic Rear Housing

You don't see it often, but the backside of any dictation microphone is as important as the front side, because that is the part that will rest in your hand.

Philips knew this and put a great deal of effort into shaping the SpeechMike Premium. Their designers have engineered buttons in such a manner as to reduce unintended use while comfortably fitting it to the human hand.


Integrated Motion

The Philips SpeechMike Premium is the first stationary dictation device to be controlled by the movement of your hand!

The motion sensor detects when it is put on the table, automatically muting the microphone. When it is picked back up it will automatically un-mute the microphone. Taking it further, Philips allows you to program custom events with this feature to do things like pause and continue recordings.


Configurable Instruction Key

Do you have commands that you frequently make use of with your speech recognition software?

The engineers at Philips designed a fully configurable instruction key at the top of the control panel.

This key enables the user the freedom of personalizing the device for common tasks.


Antimicrobial and Fingerprint Resistant Housing

The polished, pearl metal colored housing of the SpeechMike Premium is made of high-class polymers and uses antimicrobial synthetics that last for at least five years. It fights against a wide range of different microorganisms such as bacteria (e.g. pneumococcal bacilli and multiresistant microorganisms such as MRSA), viruses (e.g. HIV, influenza, etc.), fungi (e.g. Aspergillus niger), or algae. The finish is also engineered to reduce noise during use.


Laser-Scanned and Self-Cleaning Trackball

The built-in high-precision stainless steel trackball is self lubricated and the Teflon bearings resist abrasion guaranteeing smooth operation for the lifetime of the SpeechMike Premium.

The laser scanner and self-cleaning features ensure precision and durability for the most demanding user.

Should the need ever arise, the trackball can be removed for cleaning.
