Orr became involved in children's theatre beginning at the age of 10 (with her first role being in Alice in Wonderland) after she began taking elocution lessons due to her French accent,[1][2] and started to develop her repertoire of voices.

Following her move to New York City, Orr began working regularly on radio and television, and as a voice artist, having been credited over 200 voice-over roles.

She was the voice of the Snuggle bear for 15 years and narrated Aliki Brandenberg's Mummies Made in Egypt for the PBS series Reading Rainbow, and participated in a special redubbing of an episode of Late Night with David Letterman.

Her television credits include the English versions of several 1960s-1990s Japanese series such as Marine Boy, where she voiced both male and female leads.
