Bogart–Bacall syndrome (BBS) is a voice disorder that is caused by abuse or overuse of the vocal cords.People who speak or sing outside of their normal vocal range can develop BBS; symptoms are chiefly an unnaturally deep or rough voice or dysphonia and vocal fatigue. The people most commonly afflicted are those who speak in a low-pitched voice particularly if they have poor breath and vocal control.
