Problem
Many professionals need to interact with computers while their hands are occupied or speaking aloud is impractical, yet existing voice assistants require audio capture and keyboards demand visual attention, limiting productivity in meetings, on the move, or in noisy environments.
Solution
Subvocal’s under‑chin wearable, Murmur, captures the subtle muscle signals generated when a user silently mouths words. Real‑time biosignal decoding translates these patterns into text or command inputs without using a microphone or camera, preserving privacy. Users activate the device intentionally, preview actions, and can undo commands, ensuring that only deliberate inputs are executed. The system integrates with common productivity tools, enabling hands‑free messaging, note‑taking, and control of applications such as Slack, Teams, email, and AI agents. By expanding the command set over time, the device supports both immediate utility and future workflow customization.
Target Audience
Primary users are knowledge workers, remote collaborators, and developers who need hands‑free computer interaction during meetings, while walking, or in environments where speaking aloud is undesirable.
