Debi Derryberry (Mihoshi Special only)
Sherry Lynn (1994-1998)
Wendee Lee (1998-present)

Kiyone is unique in that she is the only lead character who did not feature in the original OVA series. Her first appearance in a full episode was in Mihoshi's story in the OVA special "Galaxy Police Mihoshi's Space Adventure", and evidently caused enough of a stir to bring her back as a main character in the TV series.

With her GP partner Mihoshi, they are a genuine odd couple; a sensible side to galactic policing that serves to balance out Mihoshi's manic character.

After initially being voiced by Sherry Lynn, the same person who provides Sasami and Tsunami's English voices, Wendee Lee took over Kiyone's role from the second movie onwards (though Sherry Lynn stayed on to voice Sasami and others).
