[asterisk-speech-rec] Looking for grammar CRM:00176300

[Kevin Bednar]

Very good guys, thanks for the info. Maybe I can write something to pull 
the needed fields from a db and format them properly for a grammar on 
the fly so anytime the db is updated I can run it to update the grammar.

Over telephones and radio the signal just doesn't contain enough information to reliably disambiguate between the very short words.

Even with thousands of names this is pretty effective and will be much more accurate than spelling. It's also more convenient for your caller.
