Property Value
Type: System..::..StringA string of characters from a supported phonetic alphabet, such as the International Phonetic Alphabet (IPA) or the Universal Phone Set (UPS).
Remarks
The contents of Pronunciation indicate which pronunciation the speech recognition engine used to match speech input to one of its loaded Grammar objects. Pronunciations may be defined in the speech recognition engine's internal lexicon, in a lexicon document that is linked from a recognition grammar in a loaded Grammar object, or inline in a recognition grammar in a loaded Grammar object. A speech recognition engine may also create pronunciations for uncommon words whose pronunciations are not defined in a lexicon or grammar to which the speech recognition engine currently has access.
Many Windows-based Unicode fonts, such as Courier New, support the display of IPA strings.
Examples
The following example shows a utility routine that generates a string with one of three possible formats: lexical (using LexicalForm), normalized (using Text), and phonetic (using Pronunciation). The text output is obtained from a ReadOnlyCollection of RecognizedWordUnit objects, which is obtained from the Words property on the RecognizedPhrase object.
