A PowerShell function to output text to screen as if typed by a human. I don't know why I wrote this.

Write-Human.ps1

Function Write-Human {
    <#
        .SYNOPSIS
            Use to output text as if typed by a human.
        .SYNOPSIS
            This script takes one or more strings and prints them to the screen with a slightly randomised delay between each character to emulate a human typing.
        .EXAMPLE
            Get-Content .\mytestfile.txt | Write-Human
