Timeship🙏 113 karmaOct 19, 2025@SpeechmaGreat AI voices, though still monotonous and robotic, or rather too neutral, with almost zero voice inflections! Excellent to read news, articles, essays, and any nonfiction books. BTW, computers should be allowed to TALK to us for free, like in the Star Trek TV series. Our future grandchildren will laugh at us for "paying" to use this everyday option, biting the hook to "monthly subscriptions" like gullible fish and then getting up to 1,000 words per month" under the so-called Pro version ;-) This is crazy!

I didn't get to the voices. I don't give my credit card information up front. I clicked away as soon as I saw that. It's a shame too, the pricing structure looked great.
