Features

Four-microphone array

The SpeechMike Ambient features four high-performance beam-forming microphones for ambient recording. Its wearable design allows full mobility while keeping the microphones close to the speaker at all times, ensuring greater accuracy in dynamic, noisy clinical environments—far outperforming smartphones or generic microphones.

Selectable audio modes

Different workflows call for different audio setups, and the SpeechMike Ambient is designed to meet those needs. Ambient Mode suits both conversation and single-speaker scenarios, preserving natural sound, while Dictation Mode focuses on the primary speaker and suppresses background voices. Two additional modes are available to integrators for speaker separation in conversation settings, ensuring maximum flexibility.

AI-powered audio processing

The built-in patented ambient sound intelligence automatically detects individual speakers and creates two distinct audio streams. This results in natural, easy-to-follow playback, making the device ideal for automated documentation, conversation transcription, and protocol generation.

Optimized for AI-driven workflows

The SpeechMike Ambient is engineered specifically to capture high-fidelity, single and multi-speaker audio in real-world environments—perfect for AI transcription, conversational AI and ambient scribe scenarios in clinical, and virtual assistant functions. Its superior input quality significantly enhances AI model accuracy, making it ideal for generating clinical notes, transcriptions, and real-time documentation.

Enterprise-grade security and compliance

The SpeechMike Ambient ensures secure data transmission with encrypted Bluetooth LE technology, and a secure “Passkey” pairing method. It avoids over-the-air pairing and allows only one active connection at a time to prevent unauthorized access, interference, and man-in-the-middle attacks. Tested for reliable coexistence with Bluetooth, Wi-Fi, and other 2.4 GHz devices, the system meets global standards like CE, FCC, and RCM. 

Developer-ready for native integration

The SpeechMike Ambient is fully backwards compatible with existing SpeechMikes, ensuring seamless integration into current workflows while unlocking new opportunities. With it’s comprehensive software development kit (SDK) and API access, third-party software providers can natively integrate the device into desktop and mobile applications. With full control over button mapping, device settings, and audio input, the SDK enables rapid onboarding for speech recognition platforms, AI tools, and enterprise software ecosystems. 

Multiroom connectivity and flexible use

Designed for seamless transitions between mobile and stationary use, the device can be worn with a magnetic clip or neck strap for hands-free operation. It stores up to 10 wireless profiles, automatically connecting to the nearest workstation when moving between patient rooms or work areas, eliminating the need for manual pairing. The docking station enables charging and desktop recording, while the ergonomic, lightweight build with tactile feedback ensures comfort and durability for long shifts.

All-day battery

The energy-efficient design delivers up to 10 hours of continuous recording time, ensuring full-shift battery life in a lightweight body. Users can recharge quickly via the docking station, a standard USB-C cable, or a PC USB port. This ensures reliable uptime and supports the mobile demands of clinical environments.

Hygienic and low-maintenance by design

Built with infection control in mind, the device uses hygienic, medical-grade materials and avoids the contamination risks common with handheld devices. Its smooth, polished surface resists germs and fingerprints while minimizing handling noise during operation for clearer audio capture. Compared to smartphones, it also lowers operational costs with fewer updates, simpler maintenance, and no need for mobile device management.
