Braille is a tactile writing system used by individuals who are blind or visually impaired. It consists of raised dots arranged in patterns that represent letters, numbers, and punctuation. Users read Braille by feeling the dots with their fingertips, allowing them to access written information independently. Audio formats, such as audiobooks and screen readers, provide spoken versions of text. These tools convert written content into speech, making it accessible for those with visual impairments. Both Braille and audio formats play crucial roles in promoting literacy and inclusivity for people with disabilities.
