Can Simon work linked with API to a Asterisk IVR ?
For one of my client, a small ONG active with migrants integration, I look for an Automated Speech Recognizer (ASR) linking their contact center IVR system based on Asterisk. The items needed to disambiguating are mainly in Italian and very few words: not more than 250 (languages, months, days, hours).
May you suggest me a software solution: base on Simon or others opensource Ars, available for 64-bit versions of Linux server?

I already replied to this somewhere else but here we go again: There is a pocketsphinx module for Asterisk. Just google for it, you'll find documentation.

As this is not part of KDE at all (unless you want to write a connector to Simon), please use the Asterisk support forum for further discussion.

Best regards,
Peter
