Cisco Cisco Unified IP Interactive Voice Response (IVR) 8.0(1) Leaflet

is described in the Extensible Markup Language (XML) specification at the 
following URL: 

 In particular, see the section: 

.

The Cisco CRS Engine uses a language called Nuance Grammar Specification 
Language (GSL). 

 describes sample expressions you can use to specify grammars in 

GSL. 

The following are examples of GSL language statements:

Digits [one two three four five six seven eight nine zero]

HowMany [I [want need] Digits [pencil pencils]]

In this example, the caller can say “I want” or “I need”, followed by a number 
from zero to nine, and then either “pencil” or “pencils”.

The Digit File Grammar Format (“.digit”) is based on a Java Properties File, in 
which keys are defined as “dtmf-x”, where “x” is from the set 
“0123456789*#ABCD” or one of “star” or “pound”, where values are the 
corresponding tag to be returned when a key is pressed or recognized.

You can also use an optional entry defined as “word=true” to specify that the word 
representation of each DTMF digit should be automatically included during a 
recognition.

[ ]

Only one of the words in the list must match.

( )

All words in the list must match.
