Yes. Helen Keller learned to speak aloud, though her speech was not perfectly clear and could be difficult for some people to understand.
How she learned to speak
Keller began formal speech training in the 1890s with Sarah Fuller at the Horace Mann School for the Deaf in Boston, after she had already learned language through finger spelling and Braille. She was taught to place her fingers on a teacher’s lips, nose, and throat to feel how sounds were formed and then imitate those movements with her own mouth and vocal cords.
What her speech was like
Accounts describe her speech as deliberate and understandable to many listeners, especially those who were used to it, but sometimes hard for unfamiliar people to follow. Despite these limitations, she used her voice in public lectures and speeches throughout her life, while also relying heavily on tactile sign language, finger spelling, and Braille for communication.
