What problem did Helen Keller have not to speak?

Helen Keller didn't have a problem that prevented her from speaking. She was born with a condition called deafblindness.

* Deafblindness means she could neither hear nor see. This made it extremely difficult for her to learn language in the traditional way.

* She did learn to speak, but it took years of dedicated effort and specialized teaching techniques.

So, the problem wasn't that she *couldn't* speak, but rather that she faced significant challenges in learning to do so due to her sensory limitations.
