Voice was not hip like how it is today when we released larynx (2016), it saw good growth only in China in their own android app stores (someone stole our app and put it there) and in Apple Appstore but we couldn't come up with proper monetization strategy. It got adopted only in China because the users there didn't have inhibition towards voice messaging in public unlike other demographics. This is why I'm waiting to see if the ClubHouse trend lasts after pandemic gets resolved and everyone starts moving out of their house for work.
Btw, I have created an automation for reading aloud inshorts news automatically - https://abishekmuthian.com/voice-summary-of-news/ . But a permanent solution would be for them to implement this feature or a new player for just voice summary of news which can also be immensely useful for customers like @Fraser.
