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.
