Honestly canonically speaking we don’t know much about Number One after she left the Enterprise, at some point she may have ended up working at Daystrom, where in a shift in career trajectory she went on to develop computer systems and ended up becoming the system that they use in the 24th.
Or maybe she became so revered that they honored her by using her voice as the computer systems.
Long story short this kind of makes a lot of sense in my own personal head canon.
Or Ransom got into the Cerritos compter’s desktop theme settings and selected the Una Chin-Riley voice option, and Freeman just decided to let him leave it that way.

Or the joke here is that the character was originally portrayed by Majel Barrett.
