I often mark article from newsletter I receive to read them later thanks to Pocket.
I'm also a big fan and user of the text-to-speech (playback) feature in Pocket App on iOS.
Unfortunately, the language detection is not accurate. The pronunciation of some articles is always in English even though the article content is in French. Thus, I have to use the Offline voices from the iOS that are less human in my sense.
For example, this article https://theconversation.com/les-consequences-securitaires-du-pacte-vert-europeen-237702 is in french but has a playback in english.
