I'll try to clarify: the command I posted in this topic is no longer needed to have a sound play each time a command is recognized, assuming you are running VoiceAttack v1.10 or later (v1.10.4 is the latest version at the time of writing)
You can delete the command from your profile.
After removing the old command, create a new command that simply contains either the "Play a Sound" action, or the "Play a Random Sound" action, configured to play the sound(s) you want to hear when a command is recognized.
After creating that command, adding one of the mentioned actions to it, and clicking "OK" to add it to the command list, click the "Options" button near the top of the "Edit a Profile" window, to the right of the "Profile Name" field
Then, on the "Profile Options" window, click the "Profile Exec" tab, check the box to the left of the "Execute a command each time a command phrase is recognized" option, then use the dropdown below that option to select the command you created
(the "Execute even if rejected for low confidence" option should not be checked, as commands rejected for low confidence aren't actually executed, so you wouldn't want to have the sound play for those)
Finally, click "OK" to confirm the changes to the profile options, then click "Done" to save the changes to the profile.
