You can use a free program called "Audacity" to record the file to a .wav on your windows machine.  Upload it using sftp or some transfer program to your controller, use a program called 'sox' to convert it to a .gsm file: (sox inputfile.wav -r 8000 -v .5 outputfile.gsm (-r is resample at 8000 Hz, -v is volume of 1/2... -v 1 would be no change, -v 2 would be double....)

or...purchase a license for a voice from cepstral (text to speech program, chose William 8kHz) load it on the controller, build a simple text file with what you want to say, run it through the cepstral text to speech program, run the produced .wav file to .gsm with sox, and move it into the /var/lib/asterisk/sounds/rpt directory.

Lots of ways of skinning the cat; I use the latter to convert my download weather forecast and alerts to voice to playback with DTMF commands, and the former to convert mp3s that professional announcer friends of mine send me for my tail messages and 10-minute voice ids.  (It's good to have friends/former colleagues who have Don LaFontaine style voices...:) "In a world where amateurs wonder about which machine they're on...YOU'RE transmitting on xxxxxx..."  OK, hokey.  

Do a google for Asterisk audio file creation and there's a wealth of information out there....start here:

for a good start, imho.  's where I began.  And ended up with a complete studio set-up in my basement shack...

> If I want to record voice files for my repeater, what can I use.  I see in some places it says you can use WAV, or GSM.  It lists one more format, but can't remember which one.  WAV files are the easiest for me to create.  CAn I use them?
