May it be the free-floating studio quality Precision Microphone, a microphone grille with optimized structure, built-in noise-reduction pop filter, antimicrobial surface or the world’s first motion sensor in a stationary digital dictation device – the SpeechMike Premium sets the new standard.Tuned for clarity- Free floating, decoupled microphone for precise recording- Microphone grille with optimized structure for crystal clear sound- Integrated pop filter for perfect quality- Large speaker area for premium playbackCrafted for comfort- Optimized control panel for comfortable working- Ergonomically shaped for perfect fit in the hand- Integrated motion sensor mutes microphone when not in use- Freely configurable function keys for a personalized workflow- Polished surface for reducing unwanted touch noisesDesigned for detail- Barcode scanner for streamlined documentation- Antimicrobial housing and buttons for hygienic working- Laser-scanned, self-cleaning trackball for extra smooth operationFree floating, decoupled microphone for precise recordingThe microphone in the new SpeechMike Premium is decoupled from its housing for the most incredible crystal clear recording performance ever to be delivered by a desktop dictation device. The completely redesigned microphone suspension guarantees that almost no background, touch, click, air or structure-borne noise is recorded. This technique is derived from studio microphones to make sure there are no sound distortions whatsoever – and to guarantee outstanding speech recognition results.Microphone grille with optimized structure for crystal clear soundA well-engineered microphone grille is able to make a high-end microphone as in the new SpeechMike Premium stand out even more. The hexagonal holes used for the metal grille feature three times more open surface than its predecessor, engineered to provide crystal clear recordings.Integrated pop filter for perfect qualityThe microphone area of the SpeechMike Premium is made of many different layers to make it sound as clear and original as possible. One of those is a fleece inserted above and below the microphone capsule. The fleece filters out sound distortions such as pop and hiss noise, guaranteeing perfect results even if dictating closely into the microphone.Large speaker area for premium playbackCompared to its predecessor, the SpeechMike Premium is equipped with a double sized-speaker area that enables it to play back recordings in clear and crisp quality.Optimized control panel for comfortable workingPhilips is the creator of the ergonomic zones design. SpeechMike Premium has been tested and proven by users to have the most comfortable fit in the human hand. The dictation zone is optimized to keep thumb movement to a minimum. The buttons needed for the actual dictation functions are placed centrally, in the area most convenient for the thumb, guaranteeing perfect ergonomics and non-fatiguing usage for the user. Less frequently needed function buttons are clearly arranged above and below. All buttons used are formed to give as much tactile feedback as possible.Ergonomically shaped for perfect fit in the handAs the rear of a dictation microphone is as important as the front, Philips put an emphasis on shaping it in a way so that it perfectly fits the human hand and reduces unintentional use of buttons. The trigger and the “command” button on the rear housing are engineered to be exactly where they need to be. There has never been a desktop dictation device that is as ergonomic as the SpeechMike Premium.Integrated motion sensor mutes microphone when not in useBeing on the cutting edge of technology, the Philips SpeechMike Premium comes with an integrated motion sensor, making it the first stationary dictation device that can be controlled by the movement of your hand. It detects when it’s put on the table, mutes the microphone, and once it is being picked up again it unmutes the microphone. There are plenty of situations this feature can be greatly beneficial; just think of an incoming phone call or someone stepping in your office. In addition to that, custom events can be programmed, e.g., to pause and to continue the recording.Freely configurable function keys for a personalized workflowThe Philips SpeechMike Premium is the most advanced dictation microphone to date – and to give the user even more room to personalize their devices, Philips has added an instruction key at the top of the control panel – of course fully and freely user configurable, especially useful for programming speech recognition commands.Polished surface for reducing unwanted touch noisesThe housing of the new SpeechMike Premium is made of high-class polymers. The cabinet is endued with a polished surface and the material includes a pearl metal additive providing a high quality metallic effect and making it non-sensitive to touch noises and fingerprints.Barcode scanner for streamlined documentationLink client or patient data to a recorded file simply by scanning a bar code (SpeechMike Premium barcode devices only). The scanned information is automatically attached to the dictation file, streamlining the documentation process. All identifying information is entered accurately, increasing security and potential for cost savings. The device can even be configured to automatically place scanned codes into the correct fields without having to move your mouse cursor. With the SpeechMike Premium, it is possible to scan barcodes from up to 60 cm / 23 inches away. This is twice as far as the predecessor could reach.Antimicrobial housing and buttons for hygienic workingThe SpeechMike Premium’s housing and buttons are made of antimicrobial synthetics, guarding it against all kinds of germs. Antimicrobial materials work 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 antimicrobial effect on the SpeechMike Premium lasts for at least five years.Laser-scanned, self-cleaning trackball for extra smooth operationThe SpeechMike Premium includes a built-in high-precision stainless steel trackball. Self lubricated and abrasive resistant Teflon bearings guarantee a smooth operation over the entire lifetime. In combination with a laser scanner and self-cleaning features, the trackball is as precise and durable as never before. On top of that, the trackball can even be taken out of the device for cleaning, if this should ever be required.
