Is faster speed than +200% possible?

Readest also use Edge Read Aloud voices but somehow it's able to go beyond 2x speed.

When I have the slider go all the way to the right, to the fastest speed, it's definitely faster than the Microsoft Edge browser voices and the SAPI voices when I set the rate to 10. I'd like to have the ability to set the speed more than 200% if possible.

think it not use natural (online) voices; it use some offline natural voices like ms guy from narator win11; it have limited natural voices like en fr ge es jp ko;
natural online had more options ru ua but work only online; hope after few years ms will go with similar offline models for them too;
