Hands-Free Vocal HMIs

Voice-Activated Keyboard

Introducing the first clinical and industrial HMI interface configured for dynamic speech recognition. The Keetronics Voice-Activated Keyboard integrates an offline, hardware-isolated speech recognition engine, beamforming noise-cancellation arrays, waterproof acoustic vents, and custom speak-to-macro mappings. Perfect for sterile surgical theaters, chemical refineries, and busy logistics hubs.

Hands-Free Vocal Control

Speech recognition engineered for demanding environments

Designed for surgical rooms, industrial packaging, warehousing, and chemical process control - where keeping your hands on the task is a safety or sanitary requirement.

Offline Speech Processor

Calculates voice commands directly on physical hardware. Operates 100% offline, guaranteeing zero lag and eliminating network data leakage risks.

Beamforming Mic Array

Linear multi-mic array tracks and filters the operator's voice. Suppresses high-decibel background whines, forklift alarms, and factory noise.

Vocal Waveform Status

Interactive RGB LED rings pulse to act as a VU meter. Colors confirm active listening, verified commands, or unrecognized speech inputs.

Speak-to-Macro Mapping

Dynamic mapping system translates spoken key phrases into standard keyboard scan codes or compound macros (e.g., Ctrl+Shift+Alt+S).

Sealed Acoustic Vent

Protected by hydrophobic, waterproof acoustic membranes, allowing steam cleaning and aggressive washdowns without damaging internal mics.

Hybrid Tactile Controls

Integrates physical tactile buttons or CapSense keys alongside voice triggers, supporting double-confirmation routines for critical safety tasks.

Speech Control Integration

True hands-free system interaction

Eliminate physical contact during critical steps. Keetronics voice-activated keyboards combine hydrophobic acoustic structures with high-accuracy local speech recognition chips. Ideal for medical surgical suites, cleanroom pharmaceutical lines, hazardous refining sites, and material handling cabins.

  • 100+ speaker-independent offline command vocabulary library
  • Advanced dual/quad-mic beamforming noise cancellation
  • Specialized GORE-TEX® hydrophobic sealed vent protection
  • Highly isolated preamps preventing electro-magnetic noise hums
