The most important property in controlling the checking subsystem is the ImGearRecRecognitionSettings.SpellingEnabled Property. This property is used to enable or disable the running of the checking subsystem.

If it is enabled (default), the correction of non-compliant words can be enabled or disabled. For this, the CorrectionEnabled Property and SpellingLanguage Property are used. If correction is disabled, non-compliant and suspicious words are flagged, but no auto-correction is done. When enabled, all these unchanged words are flagged, while some characters may be changed and are marked as changed. Correction is the default, so the application needs to call this function only when it wants to explicitly disable the word correction feature.

The remaining checking-related properties are specific to the particular checking system.
