🔑 Enhanced Key Takeaways
- •The device utilizes non-invasive surface electromyography (sEMG) sensors integrated into the fabric to detect subtle neuromuscular signals associated with subvocalization, rather than direct cortical brainwave monitoring.
- •The underlying AI model employs a transformer-based architecture specifically trained on silent speech patterns, allowing it to map neural-muscular activity to phonemes in real-time with a reported latency of under 200 milliseconds.
- •Privacy-focused design ensures that all neural signal processing occurs locally on a paired mobile device, preventing raw brain-data transmission to the cloud.
