Applescript Random Delay

I need to play a sound at random times throughout the day.

How can I create a random delay function, tha开发者_StackOverflow社区t then plays the file through the system audio?

delay x takes an integer for an argument.

random number from a to b generates a random integer between values a and b

try this

on run {}
    my doit()
end run

on doit()
    display dialog "hello world"
end doit

on idle {}
    set ran to random number from 0 to 10
    doit()
    return ran
end idle

be sure to save it as stay open application
