Ask HN: Would you pay for a good RSS TTS reader?

I like listening non-fiction audiobooks. There are a lot of pro-s comparing to text books, but this is not the main topic. What matter is that there are a lot of people who prefer audiobooks, judging, at least, by audible.com scale.

Why on earth there is still no service for articles TTS reading? There are some ways around, like Pocket app, that has terrible TTS functionality and some other apps with awful UX.

I really hoped someone would develop such application for years and i'd gladly pay very well for it's usage subscription, but there are no suitable apps. With Google's WaveNet TTS api anyone can build awesome TTS RSS reader.

1. Why there is no decent app for this matter? Or, if you know any, could you recommend?

2. If there is no suitable apps, would you pay for such app? Even with WaveNet voices, it will cost about $10 per regular-sized 300-400 pages book, which means quite a lot of articles can be fit into this amount.

3. What features would you like to have in such app?
