Everything is made up of atoms vibrating. Sound is a vibration. When two vibrating things come together, they will adjust to compromise each other. When the vibration of glass adjusts, the glass shatters.

Resonance.
Every object has a natural frequency. Frequency is the amount of waves passing through a certain point in a given time(mostly seconds). Humans, concrete, pencils, anything has a natural frequency.
But an opera singer can shatter a glass but not the audience. Why? Because it could be the frequency of the audience is different or that they are more elastic. Elastic objects don't break as easily. They tend to go with the flow. So instead of breaking, they just shake or vibrate.

all substances have an innate resonate frequency. If enough energy, in this case sound energy, is applied to the object at the proper frequency,it will begin to vibrate. It may vibrate microscopically with a little of the right energy, but as more is applied, it will vibrate more rigourously. In the case of a glass, it may vibrate so much that it actually breaks.

the glass reaches its resonant frequency at which point it starts to vibrate in waves it then shatters. all things have a resonant frequency, bridges are built in segments that are prime numbers so that no 1 frequency can shake the bridge since each piece has a different resonant frequency.

because the sound waves of his/her voice, if intense enough, will make the glass vibrate so much that it shatters
try it:
stick a restaurant straw in a wine glass and try a high note with your mouth very near the glass and you'll see the straw "dance" because of the vibration of the glass...

Accoustic resonance increases the vibrations until they exceed the glass's elasticity.

the sound waves are so powerful it breaks it
