Key Features
- Free-floating, Decoupled Microphone: Ensures precise recordings by isolating the microphone from device housing noise, preventing sound distortion and optimizing speech recognition results.
- Built-in Pop Filter: Non-woven fabric above and below the microphone capsule filters out sound distortion such as pop or hissing sounds, allowing for perfect recording results even when dictating close to the microphone.
- Optimized Microphone Grille: Specially designed hexagonal openings provide a three times larger open surface area than previous models, ensuring crystal clear audio capture.
- Integrated Motion Sensor: Detects when the device is placed on a table and mutes the microphone. It reactivates automatically when picked up, and custom events can be programmed for recording interruption and resumption.
- Freely Configurable Function Keys: Buttons can be personalized for each user and application, ideal for programming voice recognition commands and streamlining workflow.
- Ergonomic Design: The device's shape fits perfectly in the hand, reducing the likelihood of incorrect operation. The shutter release and control button on the back are easily accessible.
- Hygienic Surface: The SpeechMike case features a hygienic surface that inhibits germ settlement, complementing disinfection measures. The polished pearl metallic surface also resists touch noise and fingerprints.
- Extra-Large Speaker: Equipped with an extra-large speaker for clear and interference-free playback of recordings.
- Touch Sensor: Allows users to control and navigate applications during recording without switching between mouse and microphone.
