This seems like a very popular Chrome extension for listening to articles. Did well in the Product Hunt launch 😊
I use Play.ht for providing audio for my Medium readers. They are robotic voices, but it gets the job done and it's very easy to get started. You can even embed the player inside your own articles.
ryan made this productAudm is an iOS app that lets you listen to audio versions of longform feature articles from publishers like The Atlantic, The New York Review of Books, ProPublica, Outside Magazine, Foreign Policy, and London Review of Books. The stories are read by audiobook narrators.
Voice Aloud Reader is still the only app I've ever paid for, just because I received so much value from the free, ad supported version. It plays almost any file type, syncs with Pocket, Dropbox, Google Drive and it's really easy to skip or go back a sentence or paragraph.
