Sudden changes in pitch and jitters? I don't know if you program (apart from NQC
or VB), but computers have their own special way of dealing with voice data. See
if you can detect the change in pitch from speaking calmly to shouting angrily,
in the following phrase:
11010010101101000101010101010001010100100110100101010101100011101010101010101100
10101010101010101100101010010110100011101010010111010010010101001001011011100100
10101101010001101001010010100001010110100101010001000111101001001010101010
Not so easy, huh?
