Rosanne has released RULES OF TRAVEL, her first record since she lost her voice in 1998 from polyps on her vocal cords.
A pal says, "Rosanne was really in shock. She never thought about life without expressing herself through music."
Her doctor said polyps would go away after the then-pregnant singer gave birth to her son JAKE, now four.
The growths receded six months later, but Cash remained silent for another two years.
Now the 47-year-old singer is celebrating her reborn voice by teaming up with her dad Johnny, 71, for a duet on her new recording.
