Are you referring the the "Feature On Sound" and "Feature Off Sound" that play when the "Start VoiceAttack Listening" and "Stop VoiceAttack Listening" action run?
If you're not using those actions you could just remove them (VoiceAttack does not need to be listening while the command is already executing, so unless you're using the "Start VoiceAttack Listening" action to override the listening status they aren't required).
Otherwise, you could try muting VoiceAttack's sound output when those actions run:
Mute application [VoiceAttack] audio
Start VoiceAttack listening
Stop VoiceAttack listening
Pause 0,5 seconds
Unmute application [VoiceAttack] audio
However, if you do require those actions, the better choice here would be to have the loop limited to the actions that require it by using loop actions, rather than the command's "Repeating" option:
Start VoiceAttack listening
Start Loop While : [1] Equals [1]
Move mouse cursor to screen coordinates (582, 1100)
Pause 0.1 seconds
// Obtain mouse cursor's X-coordinate
Set integer [~~mouseX] value to the converted value of {MOUSESCREENX}
// Obtain mouse cursor's Y-coordinate
Set integer [~~mouseY] value to the converted value of {MOUSESCREENY}
// C# inline function to obtain RGB and hexadecimal color values for screen pixel at (X, Y) coordinate of interest
Inline C# Function: Retrieve pixel color data at (X, Y) screen coordinate, wait until execution finishes
// compare hex with 1F1117. Click1 if false
Begin Text Compare : [~~HexValue] Does Not Equal '1F1117'
Press 1 key and hold for 0.05 seconds and release
Pause 1.2 seconds
End Condition
End Loop
Stop VoiceAttack listening
That just compares a boolean value named "1" to itself, with "Evaluate 'Not Set' as false" checked, for an infinite loop.
Or you can use a "Loop Start - Repeat a Certain Number of Times" action instead:
Start VoiceAttack listening
Start Loop : Repeat 3 Times
Move mouse cursor to screen coordinates (582, 1100)
Pause 0.1 seconds
// Obtain mouse cursor's X-coordinate
Set integer [~~mouseX] value to the converted value of {MOUSESCREENX}
// Obtain mouse cursor's Y-coordinate
Set integer [~~mouseY] value to the converted value of {MOUSESCREENY}
// C# inline function to obtain RGB and hexadecimal color values for screen pixel at (X, Y) coordinate of interest
Inline C# Function: Retrieve pixel color data at (X, Y) screen coordinate, wait until execution finishes
// compare hex with 1F1117. Click1 if false
Begin Text Compare : [~~HexValue] Does Not Equal '1F1117'
Press 1 key and hold for 0.05 seconds and release
Pause 1.2 seconds
End Condition
End Loop
Stop VoiceAttack listening
