- What it is
- An MIT Media Lab paper describing a wearable that reads the electrical signals of muscles involved in speaking when a person silently mouths words, and turns them into text or commands. The abstract reports user studies and a median word accuracy.
- How much weight it carries
- Peer-reviewed conference paper from the MIT Media Lab. The abstract gives the accuracy but not the number of participants or the vocabulary size, and the device was a research prototype, so the figure describes a controlled setting rather than open conversation.
Facts taken from this source
- In the 2018 AlterEgo paper, a wearable that reads silently mouthed words reached a median word accuracy of 92 percent in its user studies.
“We demonstrate robustness of the system through user studies and report 92% median word accuracy levels.” (Abstract)
