Everyone knows her voice, but few know her name.

Well, technically, you know her as Siri, but the woman behind iPhone's sometimes-sassy personal assistant is actually voice actor Susan Bennett. Susan appeared on "Oprah: Where Are They Now?" over the weekend and spoke openly about her experience as Siri as well as her lengthy voice career.

As Susan says in the above video, her foray into voice acting was a total accident. It happened many years ago, when she was a singer who performed commercial jingles. When the voice talent didn't show up one particular day in the studio, Susan was asked to read a few lines.

"I thought, 'Well, this is something I could do,'" Susan says. "So, I got a voice coach and an agent, and that was that."
