Ann Syrdal

Syrdal died of cancer on July 24, 2020, in San Jose, California.

She was named a fellow of the Acoustical Society of America in 2008, for her work in female speech synthesis.

After the grant ended, Syrdal took a job at AT&T Bell Laboratories. At the time, synthesized voices were primarily male. In 1990 she developed a system that could generate a female voice. In the 1990s she joined a project that developed a new method of speech synthesis; instead of creating the sounds artificially, the synthesis joined fragments of recorded speech to create new words and sentences. Sydral oversaw the initial recordings, of six women's voices. In 1998, AT&T's "Natural Voices" system won an international competition for speech synthesizers, using a female voice.

After receiving her PhD, she began research work at the University of Texas at Dallas's Callier Center for Communication Disorders. In the early 1980s she received a five-year grant from the National Institutes of Health, and began studying the mechanics of human speech at Stockholm's KTH Royal Institute of Technology and the Massachusetts Institute of Technology.

Ann Kristen Syrdal (December 13, 1945 – July 24, 2020) was an American psychologist and computer science researcher who worked with speech synthesis technology. She developed the first female-sounding voice synthesizer.

Syrdal was born on December 13, 1945, in Minneapolis. Her father, Richard, was a physicist and engineer; her mother, Marjorie (née Paulson) was a sales clerk. She was raised by her mother after her father died when she was two years old.
