Discovered the issue with voice on Iaudio and how to fix it

[vulpine]

I posted in another topic here yesterday about voices not working on Iaudio x5, apparently someone else was having the same issue.  See link to the other topic for the issues.

The problem is that when you unzip the voice file it is named as an example "english_Reed.voice"  By renaming it in the langs folder to "english.voice"  it fixes  the problem.  I assume this is the same for all of the March 7th voices as I was getting no speech with them at all.  Since doing the rename everything works fine.

I'll test some other voices just to see if they are all the same.
