-    <p>Some people have sensory limitations or need to perceive content through multiple senses. For instance, people who are deaf-blind have little or no use of audio and visual content, and need tactile forms of content (such as <a href="#braille" class="termref" shape="rect">Braille</a>), while people with dyslexia may need to hear and see the text to better understand it.</p>
-    <p>Content in textual form can be converted into other forms and is therefore particularly useful. However, text-only content poses barriers for many people who have difficulty with written language. Graphics and illustrations can be made accessible and often improve understandability, ease-of-use, and satisfaction with websites and applications for everyone.</p>

     <p>In some cases, content can be converted into different forms using software or hardware. For instance, text can be converted into speech using text-to-speech software. In other cases, content authors need to provide alternative forms of the content. For instance, textual descriptions for images and captions for audio content need to be created with at least some level of human intervention. Sometimes software tools, such as voice and image recognition, can assist authors in providing such alternatives but the conversion is usually not fully automatable.</p>
