Audacity - editing sound

From the above audio I have changed the tempo to help hide the identity of the antagonist character, so far I have changed:

• change tempo = 20.001 - length 3.20 + 2.67
• speed 1.061, percent change = 6.072
• pitch = 1.000
• amplify - amplification = 2.91
• click removal - 244 = threshold, max spike width = 10
• echo = delay time 4, decay factor = 0.7
• leveller, degree of levelling = light, noise threshold = -20db
• phaser stages = 10, dry/wet = 63, LFO frequency (Hz) = 1.2, LFO start phase = 40, depth = 76, feedback = -10
• normalise = -2.0

From the above changes I have created a deep hard to crack voice that may change depending on whether it fits correctly with the character.
