SetWordlistCoercionHRC
2.0
Specifies to what degree input must match a word list set into an HRC. SetWordlistCoercionHRC determines the influence a recognizer's word list or dictionary has on the
recognizer's guesses.
int SetWordlistCoercionHRC( HRC hrc, UINT uCoercion )
Parameters
hrc
Handle to the HRC object.
uCoercion
Coercion flag. This can be one of the following:
SCH_ADVISE
The word list serves only to advise the recognizer, but lacks a strong degree
of influence. Recognition results are not strongly coerced to match the word
list.
SCH_FORCE
If the recognizer's guess is not found in the word list, the closest matching
entry in the list is returned. For example, if the recognizer interprets
writing as "Cana", it returns "Canada" from a word list of country names.
SCH_NONE
Do not coerce. This flag can be used to turn off a previous request.
Return Value
Returns HRCR_OK if successful; otherwise, returns one of the following
negative values:
Constant
| Description
| HRCR_ERROR
| Invalid parameter or other error, including an attempt to set coercion with no
word lists set into the recognition context.
| HRCR_MEMERR
| Insufficient memory.
| HRCR_UNSUPPORTED
| The recognizer does not support this function.
|
Comments
The default type of coercion a recognizer provides is SCH_ADVISE. That is,
results are not strongly coerced to any word list that might be set into a
recognition context.
Coercion is used only if a word list (HWL) has actually been set into an HRC with SetWordlistHRC, or if the recognizer's dictionary is enabled by EnableSystemDictionaryHRC. If the HRC is configured with a word list and the recognizer's dictionary is also
enabled, coercion is done on both; the priority depends on the recognizer.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
