Eli5: How do people who’ve never had any hearing, but who receive cochlear implants later in life, understand their “native” language?

504 views

I’ve seen videos of people sitting in the doctor’s office getting their implants turned on, and they’re responding to questions like, “Can you hear me?” or “How is the volume?” How do they know what they’re being asked if they’ve never before heard how language sounds?

So coming from a family where my Mom, aunt, and both Uncles were mostly deaf (They all had hearing aids since they were kids), and 3 of them ended up with cochlear implants.

We never did sign language in our family, instead everyone basically learned how to read lips, so even when my family had their hearing aids off and had no hearing, we could communicate perfectly fine with them as long as we were looking at each other.

I would guess that is what a lot of what you are seeing is. They hear sound, but even if they have no idea what the words sound like, they can still perfectly comprehend by reading lips, just like they could when they were hearing impaired.

Eventually, you begin to put the sounds together with the language and mouth movements you already know.
