This seems only useful to people who once had a voice, then lost their voice. Because only this way, would they have a unified mapping of voice cord movements to actual voices. Deaf and mutes can't really use this. It also basically mandates a patch to your throat, because no way of detecting vibrations otherwise. I wonder if there are visual based ways, like sign->text, expression->text, that would benefit from the larger developments in LLMs. Like an LLM that has access to your conversation history, so when you give your smartphone camera a hand sign and a smile, it can guess and output an entire intended speech.
