This is really neat. It looks like you're using google cloud's text to speech -- are you footing the bill for this, or do you have a plan to monetize? I run ListenLater.fm, which does something similar (You add articles to a podcast feed via a bookmarklet or browser extension, then listen to them with a personalized podcast feed.) Your implementation is incredibly clean, but I'm curious what's to stop people from using it a lot and you ending up with a huge bill. One thing I'd immediately recommend you look out for is people using it to turn free online books into audio versions. This is the use case for a few of my customers, and because google charges per character, it can be difficult to make money even when charging a few dollars a month. Good luck, and please consider shooting me a message on Twitter or via email (in my profile.)
