Sally is sweet but also motherly like. She's similar to Rachel but definitely older and more mature to her. While Rachel has more of a young adult tone sally has a more distinguished adult tone. She's also is lest extroverted. And kind of stressed about what she says. Being a bit overwhelmed and self conscious at times However it isn't a defining trait. She should sound high but not as high as Rachel, Most of the time in a very calm and normal voice
