Sorry to drop in on this thread but I'm relatively new to Sphinx and speech recognition. I'd like to know if anyone has successfully setup speech recognition in Asterisk for Spanish users. Sphinx doesn't seem to have Spanish acoustic and language models and I don't think I'll ever have the time or know-how to make my own.
My requirements are similar to the OP's:
basic "yes", "no", get an 8 digit number, etc.
Actually, "yes" ("si") and "no" work well with the English models. However, accuracy is not that great when it comes to recognizing digits zero to nine in Spanish.
Thanks for any suggestions,
