Casting calls need to be written right. You want to get auditions that really encapsulate your character, and auditionees want a great chance to succeed. To do this is simple - write your casting calls properly and completely...and avoid the 'No Accent' comment like the plague.
The simple fact of the matter is, there is no such thing as 'no accents'! Everybody has an accent, it's just different depending on who is hearing it.
Many times I have skipped over an audition simply because I had no idea what accent they WERE looking for. Sometimes, if a part looks particularly interesting, I might drop a message to find out what they are after. But as a casting person, you can avoid endless questions and just cut to the auditions if you make your instructions clear and precise.
The best way to do this is to add a simple line or two describing what voice you want. For example
Voice Type; Young teenager (13-14 years), unbroken male voice, North American accent.
or
Voice Type; British 'Essex Girl' type voice (high and ditzy/giggly), female in her 20s
The bottom line here is - specify your accents. We all have one!
