In 2 of say3D's alternate syntaxes (syntaxes 2 and 4 here: https://community.bistudio.com/wiki/say3D) it can take a set of optional parameters as an array. However, the first optional parameter, maxDistance, isn't really optional because the command requires a minimum of 2 elements in the parameter array and will throw a script error if you try to leave out the maxDistance parameter.
