A text-to-speech converter changes text from documents, files and websites into audio. Converters can either output audio directly to the computer's speakers or save the output to an audio file.
Types of documents that text-to-speech converters can interpret include Microsoft Word documents, Adobe PDF files, e-books, text files and Web pages. Optical character recognition software is required for certain e-books, photos and scanned documents. Other features of text-to-speech converters include batch conversion for multiple documents, controls to adjust reader voice and speed, text highlighting and device syncing.
Text-to-speech converters allow students to listen to textbooks and notes, increase proofreading effectiveness and help people with learning disabilities, such as dyslexia. Text-to-speech converters also help people multitask and allow the blind to listen to written text.
