Speed Racer Controls

Speed Racer lets you try copying at a higher speed than you are used to, and then gradually reduces the speed to a more comfortable one. Or you can start at a slower speed and gradually increase it.

You can choose to vary the character speed, Farnsworth speed, or both:

The table below shows the percentage speed change along with the character and Farnsworth speeds for each time the message will be played.

You can adjust the number of times the message is repeated (2 to 5), the maximum percentage change (-99% to +100%), and your base character and Farnsworth speeds:

Message speeds
Repeat Percentage Change Character Speed Farnsworth Speed
%
1 None

The Farnsworth Speed cannot go above the Character Speed: where the modified Farnsworth Speed has been limited by the Character Speed, it is shown in red.

Your advanced timing settings in mean that there is no simple Character Speed and/or Farnsworth Speed. The boosted speeds will use precise Character/Farnsworth speeds and the final play will use your custom settings.

Speech Error

Speech has stopped working

Safari sometimes has issues with speech synthesis. To fix this:

  • Close Safari completely and reopen it, OR
  • Toggle content blockers off then on again in Safari settings (or on then off)

Alternatively, you can also disable speech in the settings to continue without it. Try not to let Safari go into the background while the tool is speaking (don't change to another tab or app), or lock the device, as these actions can cause problems with speech.

Speech Error

Speech did not start

This may be because you are offline. If so:

  1. Open the controls
  2. Choose a voice that is labelled as "local"
  3. Try again

Alternatively, you can disable speech in the settings to continue without it.
