Sathvani is a research and development lab building the world's first patented artificial vocal chord — a soft bio-electronic prototype engineered to restore natural speech for people who have lost theirs.
Over 65 million people live with severe voice disorders. Existing solutions — electrolarynxes, esophageal speech, text-to-speech devices — sound mechanical, distant, other. Sathvani exists to end that compromise.
Our patented device sits at the site of the original vocal folds. A biocompatible elastomer membrane, driven by micro-actuators, oscillates in response to subglottal pressure — reproducing the natural harmonics of a human voice rather than synthesizing sound electronically.
Finite-element simulation of soft-tissue resonance across 80–1100 Hz.
In-house PDMS composites tested for 10⁷ oscillation cycles.
sEMG pickup on the strap muscles translates intent to pitch and volume.
Minimally invasive transoral placement with existing ENT workflows.
On-device DSP tunes the membrane in real time to the patient's airflow.
Filed claims covering the airflow-driven resonant vocal prosthesis.
