What is text-to-speech technology (TTS)?

Text-to-speech (TTS) is a type of assistive technology that reads digital text aloud. It’s sometimes called “read aloud” technology.
 
With a click of a button or the touch of a finger, TTS can take words on a computer or other digital device and convert them into audio. TTS is very helpful for kids and adults who struggle with reading. But it can also help with writing and editing, and even with focusing.
 
TTS works with nearly every personal digital device, including computers, smartphones, and tablets. All kinds of text files can be read aloud, including Word and Pages documents. Even online web pages can be read aloud.

How does text-to-speech work?


The voice in TTS is computer-generated, and reading speed can usually be sped up or slowed down. Many TTS tools highlight words as they are read aloud. This allows the user to see text and hear it at the same time. Some TTS tools can also read text aloud from images. For example, a user could take a photo of a street sign on their phone and have the words on the sign turned into audio.
