Some people like those, some of the time. I too enjoy a good Conan or Hardcore History podcast but many other podcasts I listen to are basically audiobooks where, if the voice is good enough, I'll listen to them. History of Rome is a prime example, it's essentially a very long audiobook where the reading voice makes nearly no difference to me.
We highlight that the creativity comes from the human. The text to speech is the AI Component. There is a script assistant that can help you adjust the tone of the text, but the creativity always comes from human.
Hm, based on their site it looks like it's more of an editor where you type content that's then converted to speech, there's nothing in there that necessitates that the content be AI generated. Seems to me more of a competitor to https://www.descript.com/ than anything.
In fact, the voice narrating Hardcore History is so.. American (no offense to anyone), swapping in another voice would actually be an improvement for me.
