She has been judging talent on "The Voice" since its first season.

And Lea Salonga just reminded viewers why she's a constant feature on the talent contest, showcasing her knack for evaluating a person's singing abilities when she appeared on "I Can See Your Voice."

Unlike previous celebrity guests, Salonga had little trouble separating contestants who could back their boast with actual talent from those who were trying to fool her into thinking otherwise.

She was on point all night and easily whittled down the pool of six to two --both of which turned out to be real singers.

But it was MJ Cayabyab, an aspiring actor and singer who works as a call-center agent, who convinced Salonga that he's the real deal. His prize? P25,000 and a "Bakit Labis Kitang Mahal" duet with the Tony winner.

Cayabyab also automatically qualifies for "Tawag ng Tanghalan."

Based on a Korean show of the same title, "I Can See Your Voice" airs Saturdays after "Maalaala Mo Kaya" and Sundays after "Rated K".
