If you prefer a physical trackball, the Philips SpeechMike Premium LFH3500 puts it beside push-button dictation controls. Its wired USB connection suits a fixed workstation, letting you move through documents and record speech from the same handset.
Why choose the LFH3500?
- A trackball you can feel: Roll the trackball to move the cursor and use the mouse buttons for selection. The LFH3500 uses a trackball, rather than the touchpad found on Premium Touch models.
- Reduced handling noise: The microphone is suspended separately from its housing, with a pop filter that helps reduce noise from handling and close dictation.
- Direct recording and playback: Push buttons and the built-in speaker suit repeated dictation and review at a desk.
- Personalized commands: Map the configurable keys to supported actions in your speech-recognition or dictation application. The removable trackball also allows cleaning when required.

Applications and setup
The LFH3500 is a USB audio input for supported speech-recognition applications, including Dragon Medical One (DMO) and Nuance Dragon Professional 16. Use a supported Windows workstation for DMO and configure button actions through the application's integration or Philips SpeechControl.
Philips SpeechLive explicitly supports LFH3500 browser dictation. Connect it through the documented Chrome or Edge hardware setup, using Philips Device Connector and Event mode where required. Audio input, recording commands and trackball mouse control serve different functions. Philips lists Windows and macOS hardware configuration, with some Mac functions limited; verify your application and remote-desktop setup when matching the microphone to a workstation.
Philips SpeechControl drivers and configuration tools are free downloads. Paid dictation and speech-recognition applications are purchased separately; this hardware offer includes no paid license or subscription.

The Philips LFH3500 with voice recognition software has improved my documentation as a doctor. The device's high-quality recording ensures accurate transcriptions, saving me time. Voice recognition changed everything. It makes dictating notes easy, which boosts my patient care productivity.
Dr. E. 5/5
I have to say, the speech recognition capabilities of this product are truly remarkable, particularly when used with the Dragon software. It's easily the most precise transcription setup I've ever used. However, I did encounter some difficulties when trying to integrate it with Dragon Professional Individual 15, and setting it up ended up being more complex than I expected. Although it functioned well for about 10 months, it suddenly stopped working, but thanks to the efficient warranty service, I received a replacement quickly. Despite these challenges, I'm currently pleased with its performance and believe it's an invaluable tool for my transcription needs.
Jacob A. 5/5
The Philips LFH3500 got better and it's really light and thin. It works super well. Doctors find it easy to use the buttons.
Isabella M. 5/5
The Philips LFH3500 is a good choice for a dictation microphone if you want quality and ease of use. Even though it has a few small problems, it is a small, useful tool that can greatly increase productivity.
