I’d bet this is useful for a range of memorization tasks other than language learning. I imagine this works because it strengthens the signal to noise ratio by pairing auditory stimulus with vagus nerve stimulation. It’s kind of like how reading something out loud can help you remember it, only in this case it’s like you are reading aloud and listening to someone else read at the same time. I wonder if it could be used to improve reading comprehension. Say you are reading a story, maybe each character has their own waveform, and as you read or listen the stim pulse changes based on who is talking. Or lets say you are reading a math textbook. You could label different variables with different stim pulses, which might make it easier to follow complex logic or minimize the need to re-read different sections.
