I have exactly the same issue. Found it while trying to use Festival
If I use the italian voice I get the same error, and if I use the
english voice it works flawlessly.
Steps to reproduce:
install festlex-ifd and its dependencies.
run festival with italian language:
festival --server -b --language italian
Try to use the Festival function in Asterisk
You will get no audio and festival will print an error that states
"SIOD ERROR: wrong type of argument to get_c_utt"
