Electra's Japanese seiyuu, or voice actress, is Kobayashi Ai.
Her description from the official Cowboy Bebop website: "Kobayashi is
a leading actress in the theater troupe Team Happo Bizin, looks great in
battle-dress, and specialises in gun-play. She has also appeared in commercials
and on TV, and has done extensive voice-over work. In the anime world, her
roles have included Chako in the latest Crayon Shin-chan movie, The
Adult Empire Strikes Back, and the character of Lili in Turn-A Gundam."
Although Kobayashi hasn't had much experience with voice acting in anime, the
director of Cowboy Bebop, Shinichiro Watanabe, said, "I knew exactly
what kind of voice I wanted. Especially with Ai- the moment I heard her demo
tape, I thought: 'That's it! She's Electra!' With Tsutomu [Vincent's seiyuu],
too, I felt that I had exactly the right voice. Dramatically, I wanted to get
people who could give a raw, naturalist feel to Bebop."
Electra's voice actress is Jennifer
Hale. She has done voice work in several popular cartoons and video games. I
haven't heard her before, so I'm not aware of her range or acting ability, but
she's probably quite good. Some of her roles are below.
