[aprssig] D-STAR VOICE value?

It sounds like crud from my limited experience.  I went to look at it at 
HRO Atlanta.  The store has a radio that can get into a couple of local 
repeater setups but no one sounds anything close to what I would 
consider "good sound"  Like the P25 systems the local police are putting 
up.  Not ready for prime time and I don't think it ever will be.
