La risposta di Cyberon:
Dear customer,
Thanks for your inquiry, and we apologize for the incovenience we've caused.
Cyberon Voice Commander does include the command "Si" for confirming the request, however, the command "Si" is too short that sometimes the sound might be ignored, we would like to respectfully suggest you try the command "Conferma" instead. We'll keep investigating this issues, and will publish an update immediately once we have it improved.
Have a nice day!
Regards,
