1.) Browsers offer extensions that turn text into audio speech. Do a search for your browser name and extensions and then "Text to speech". I used Chrome and found many options, then tested two of them. I particularly liked "Natural Reader". It only gives you a limited amount of text you can listen to for free, but the subscription cost is very reasonable. It's about $100 for a year. This extension allows you to choose one of 4 voices that sound very lifelike. You can upload documents into it easily - and it offers an ios and android app for smart phones and tablet use.
I also tested "Read Aloud". I did not like this one as much. The voice sounded like a computer, and it has fewer features.
I recommend searching and then taking a look at the ratings, review and features and then trying one out.
2.) Some of our library databases offer text to speech from within their platform. Some of your readings may be from one of these platforms. I'd be happy to help you with this if you want to make an appointment and bring along some of your readings and we can take a look. There is a link below to make an appointment.
There is more information at this guide compiled by Ithaca College Librarians. It talks about and links to more information on text to speech software and extensions and options within library research platforms.
