Susan Bennett’s voice has always been special. Back at the start of her career, she toured as a back-up singer for musicians like Burt Bacharach and Roy Orbison, while also singing jingles. In July 2005, however, she took on a recording project: recording jibberish phrases for one month. It was for the text-to-speech company ScanSoft, a phone messaging system that would ultimately become Siri. Through the nonsense recordings, Bennett provided ScanSoft with all the sounds of the English language. Once in the hands of programmers, those sounds grew into the sassy virtual assistant we know today. Bennett’s story, in full over at Type Form, is a fascinating one.
