[arm-allstar] Voice speed

[Patrick Perdue]

And also, keep in mind that, in the case of .gsm files, you're dealing 
with already compressed audio. Processing and compressing again will 
give you twice the artifacts. For that reason, I suggest staying with 
linear PCM or ULAW. HamVoIP ships with GSM files, I suppose to save 
space. Lots of HamVoIP's scripts are hard-coded to look for specific GSM 
files. I changed out my entire sound pack and recursively found and 
replaced .gsm with .ulaw in several key places.
