Built in about a month with roughly 50 hours of training data, it achieves a 15.6% word error rate and works across different speakers with similar accents. The approach is immune to noisy environments since it doesn't rely on sound waves. Current limitations include the bulky off-the-shelf probe, but a miniaturized adhesive patch form factor is considered feasible as the technology matures. ## Full article daily.dev links to this article rather than hosting it.
