You can pass Espeak recordings around legally. It's just GPL. The license applies to the software, not the content produced via it.
I will attempt to remember and find the time to take my demo recording of this on Rust compiler source code that's currently in dropbox and put it up somewhere more permanent. I doubt Dropbox will care for me much if I allow HN-volume traffic to hit my account. It's Espeak using an NVDA fork with an additional voice that some of us like, so vanilla espeak is in the ballpark.
What I don't remember is if vanilla non-libsonic espeak softcaps the speech rate. It might. I believe new versions of espeak integrate libsonic directly, but that old versions just silently bump the speaking rate down if it's over the max. I haven't used command line espeak directly for anything in a very long time.
Libsonic is an optimized library specifically for the use case of screen readers that need to push synths further: https://github.com/waywardgeek/sonic
