This isn't really a question. I already know the answer. This is just to test your knowledge. I'll give the 'Best Answer' rating to the person who gives me the correct answer. (The answer must come with a reason)

Yes it can and I have seen it done. The voice had a very strong and clear voice. She was able to maintain the note for an extended period of time (she was an opera-trained singer). The sound waves were of a wavelength that created resonance with the crystal glass. The glass vibrated enough to break the crystal apart.
I know this was on “Mythbusters” before. The were able to break the glass using recording equipment.
yes, due to the frquency of the waves… just as a nuclear bomb relies on the shock waves for its massive destructive properties
Yes…all materials have a resonant frequency that can create uncontrolled oscillation. See the Tacoma Narrows bridge video as one of the most famous examples.
Yes … as long as the voice is loud enough (i.e. amplified) and directed at the glass. If it is at the resonance frequency of the glass, it can cause the glass to vibrate so violently that it shatters.
Here’s the mythbusters video:
