I had a platform where anyone could summarize web content and share it through voice - https://web.archive.org/web/20210225163329/https://larynx.io/ and bots which auto summarized web content to audio over Twitter, Messenger, Telegram & Slack.

I agree that human voice summary as in InShorts are still better as humans could add more context to the summary which the algorithms are not capable of now, but things are changing fast.
