Neat question! Speeding up a recording of someone's voice simulates a change in frequency of their vocal vibrations. Pitch is directly related to these vibrations, and the pitch goes up (sounds higher) the faster the vibrations are occurring. So, when a singer hits a really high note, their vocal cords are very tight and are vibrating incredibly fast (increase in frequency). Fast forwarding a voice recording has the same effect...pitch, frequency, and vibrations are all related, and they all increase when a voice recording is sped up.

As you probably know, sound moves in waves we call vibration. When a long heavy string is plucked it vibrates slower than when a short thin string. The thick long string has a lower pitch than the thin short string. When you speed up sound on a recording, you force the vibrations to increase in speed too, raising the pitch.

The waves are being generated closer together. The closer the waves, the higher the frequency.

when you speed up a sound wave you are actually compressing it to increase the frequency. when you increase the frequency of a wave the energy also goes up, which causes the sound to get a higher pitch.

Because the waves increase in frequency.
