Hello,
I read old 2003 post
http://support.plumgroup.com/viewtopic. ... 6bf85f#p45
and wonder if it is still valid. Does current ASR engine is able to do it now?
Regards,
Saulius

Hi,
Yes, this post still holds valid even today. The Plum IVR Platform cannot convert arbitrary, free speech to text.
Generally, you still want to follow this advice:
Useful speaker independent speech recognition systems work by constraining and validating user speech. This is done by:
1. Carefully constructing the voice user interface to prompt the user to say things in a form that is expected by the system. e.g. "What month would you like to travel?" rather than "When would you like to travel?"
2. Validating user input against a finite list of responses. e.g. "Say the name of the person you would like to reach," is constrained to the list of names in the system, perhaps the list of employees at a company site.
Also, just like human operators, the IVR would still encounter issues such as the spelling of names (e.g. letters like "m" or "n").
