HD 202696 b
HD 202696 b is a confirmed sub-Neptune exoplanet 615 ly from Earth in the constellation Vulpecula, discovered in 2019 by W. M. Keck Observatory.
Radial Velocity: spotted by the gravitational wobble the planet tugs in its star.
Its orange dwarf looks 4.1× wider than ours, bathing the surface in amber-orange light. A year here lasts 518 days, and at an estimated 219°C (427°F) it is blistering.

Your voice would sound high and thin, almost cartoonish.
Assuming Earth-like air at this world's temperature of about 219°C (427°F), sound would travel roughly 31% faster than on Earth, so your voice would sound high and thin, almost cartoonish. The real atmosphere is unknown, so this is a best guess.
