I know that others have used the current code to decode speech, maybe
someone can confirm it.

I haven't worked with the code for a while and so can't confirm it,
but it has worked for me in the past.

Maybe I find the time to try it within the next few weeks, if possible
I will also try to provide a sample capture from a test TETRA network
so everyone can try the sample. "Test TETRA Network" means from a
network under our control run in a faraday cage so that there are
no legal issues providing the capture.

Best regards,
