Word Lists
A word list acts as a broad alphabet set. A list consists of valid words that
can influence the confidence a recognizer places in a guess. After guessing at
a word (or phrase), a recognizer can search for the guess in one or more word
lists. Locating a guess in a word list helps verify the validity of the guess.
A word list can consist of a small group of words permanently stored in the
recognizer's data segment. Often, however, the words reside in an accompanying
file that the recognizer reads as required. A word list file should be in
standard ANSI text format, one word per line, with each line ending in a carriage
return and linefeed. This allows the user to emend the files, if necessary, with a
text editor.
A recognizer that uses word lists should export the
ReadHWL and
WriteHWL functions. These functions read and write standard word list files, enabling
an application to move words directly between a file and an
HWL object.
The table below lists the exported functions for a recognizer that uses word
lists.
Function
| Description
|
AddWordsHWL
| Adds a specified collection of words to an existing word list in memory.
|
CreateHWL
| Creates a word list in memory, either empty or containing a given list of
words.
|
DestroyHWL
| Destroys a word list, invalidating the handle.
|
GetWordlistCoercionHRC
| Retrieves the current degree of influence a word list or the system dictionary
has on the confidence level of a guess.
|
GetWordlistHRC
| Retrieves a word list from the HRC object.
|
ReadHWL
| Reads from a file into an empty word list. The words must be in ANSI text
format, one word per line, each line ending with a carriage return and linefeed.
|
SetWordlistCoercionHRC
| Specifies the influence a word list or the system dictionary should exert on
the confidence level of a guess.
|
SetWordlistHRC
| Sets a word list into the HRC object.
|
WriteHWL
| Writes from a word list to a file. The words are written as ANSI text, one
word per line.
