CVP Micro-Applications
Get Speech and DTMF Input Collection
Contrary to its name, the Get Speech micro-application can also be used to collect DTMF input. For
certain grammars, the caller could type a number, time, or currency rather than saying it.
certain grammars, the caller could type a number, time, or currency rather than saying it.
Although the Get Digits micro-application is capable of providing the same type of functionality, it does
not allow for validation at collection time. If a caller inputs 2 5 0 0 in response to a Get Speech prompt
prompting the caller to enter a time, the Get Speech micro-application would detect that “twenty-five
hundred hours” is an invalid entry. With the Get Digits micro-application, this kind of validation would
need to be done using additional Script Editor nodes.

Note
The caller cannot mix DTMF and speech in a single input, even if both are enabled. Once he starts
talking, he cannot key-in characters, and vice versa.

Note
Regardless of the collection type (that is, “voice” or “DTMF”), caller input from Get Speech is always
written to the user.microapp.caller_input ECC variable.
