All EBSCOhost databases provide a text to speech option for HTML Full Text articles. However, many articles are not available in HTML. When you have located an article, click on HTML Full Text and there will be an option to listen. You can also download these audio files in MP3 format.
Newer PDFs in EBSCO are ADA compliant. EBSCO Publishing began providing its scanned PDFs with an Optical Character Reader (OCR) text layer in September 2004.
Gale Databases (such as Opposing Viewpoints in Context and Contemporary Authors,) provide a Listen function for full-text articles. Wherever the Listen icon is present ( ), there is the option to have the document read aloud. The Listen tool also allows you to download the audio file as a MP3.
ProQuest databases contain many PDFs which are ADA compliant. However, older content was created from scanned images of original text that is not accessible to screen readers. This content is identified throughout ProQuest with the label 'Scanned image PDF.'
