Born in Taipei, Taiwan, Yeh immigrated to Canada at the age of four with her family and grew up in Victoria, British Columbia.

In 1992, Yeh collaborated with a couple of other western artists, recording "I'm Always Dreaming of You" with Tommy Page in 1992[4] and "I Believe in Love" with James Ingram the following year.

In 2002, Yeh re-entered the Cantopop market, released the record "Can You Hear", and performed a series of concerts in different countries.

Yeh has also collaborated on a number of soundtracks (mostly on Tsui Hark's movies with scores by Wong Jim), including "Lai Ming But Yiu Loi" from A Chinese Ghost Story (1987), which won the Best Original Song award at the 7th Hong Kong Film Awards.

Yeh was one of the earliest Overseas Chinese celebrities to enter the entertainment industry in China during the 1980s and one of the few from an English-speaking country.
