SpeechMike Premium LFH3500 Dictation Microphone features
Free floating, decoupled microphone for precise recording
The 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.
Optimized microphone grille and integrated pop filter for crystal clear sound
The metal grille comes with specially designed hexagonal openings engineered to provide crystal clear recordings by allowing significantly more sound to reach the microphone. A fleece inserted above and below the microphone capsule 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 playback
Compared 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.
Built-in support for Nuance speech recognition for a hassle-free ‘plug and play’ installation
Philips SpeechMike is designed to work seamlessly with Nuance speech recognition and is also supported by leading hospital information systems (HIS), radiology information systems (RIS), and picture archiving and communication systems (PACS). With native, built-in support for these systems, users can simply plug in the device and start using it immediately, without requiring any extra installation steps.
Ergonomically shaped for perfect fit in the hand
The device is designed to fit perfectly into the hand and reduce unintentional pressing of buttons. The trigger and the ‘command’ button on the back of the device are engineered to be in easy reach for the fingers.
Wear-free slide switch or push buttons for comfortable operation
The SpeechMike Premium comes with a slide-switch or a push-button operation. The slide switch is wear-free and ergonomically shaped with a softly ribbed surface for smooth tactile feedback and comfortable and intuitive utilization. In addition, our engineers implemented a millionfold proven contactless slider detection, making it completely wear-free for an extra-long lifetime.
Integrated motion sensor automatically switches between recording modes
Being on the cutting edge of technology, the SpeechMike Premium comes with an integrated motion sensor, enabling automatic switching between different microphone modes depending on device usage. When the device is placed on a desk, it can automatically switch to conversation mode to support ambient voice recording and multi-speaker recording scenarios. When picked up again, it switches back to dictation mode. Depending on the configuration, the motion sensor can also automatically mute the microphone when the device is placed on a desk.
Trackball for integrated mouse function
The device comes with a trackball. This allows the user to easily control and navigate within applications while recording, without having to switch between the mouse and microphone. The trackball can even be taken out of the device for cleaning, if this should ever be required. The self-lubricated and abrasive resistant Teflon bearings guarantee a smooth operation over the entire lifetime.
Freely configurable function keys for a personalized workflow
The 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.
Hygienic surface
The hygienic surface of the SpeechMike housing physically hinders the colonization of germs and thus improves the efficiency of the usual measures for disinfecting the device. The polished, high quality pearl metal surface also makes the device non-sensitive to touch noises and fingerprints.
Smart, backwards compatible firmware for extra flexibility
Customers can upgrade from their previous SpeechMike model without installing additional software. For integrators, this means no changes need to be implemented and the existing SDK can be used. The SpeechMike Premium is compatible with Mac and Windows operating systems, as well as virtual environments such as Citrix, VM Ware and Hyper-V. It can be configured using SpeechControl, the convenient Philips hardware management tool.
