Kavi Watches with Grandpa

Kavi wanted to watch a nature show with Grandpa Owl — but the room had to stay quiet, and Grandpa's ears don't hear soft sounds anymore. "Oh no, how will we know what they say?" Kavi hooted. Then Kavi remembered a special helper. Tap, tap — and the words of the show appeared right on the screen, under the pictures! Those words are called captions. Now Grandpa could read every word, even with the sound off. "Clever Kavi," Grandpa smiled. Devices have many such helpers — captions show the words, read-aloud speaks the words, and big text makes the letters bigger. These are accessibility features: they make tech work for everyone.
