IsPronounceable Method

The IsPronounceable method determines if a word has a pronunciation.

Additionally, the SpeechWordPronounceable constant returned by this method indicates whether the word exists in the grammar object's lexicon. Words are likely to be pronounceable even if they are not found in the lexicon.

ISpeechRecoGrammar.IsPronounceable(
     Word As String
) As SpeechWordPronounceable

Parameters

Word

Specifies the Word.

Return Value

A SpeechWordPronounceable constant.

Example

The following Visual Basic form code demonstrates the use of the IsPronounceable method.

To run this code, create a form with the following controls:

Paste this code into the Declarations section of the form.

The Form_Load procedure creates a grammar and loads the general dictation topic. The Command1_Click procedure passes the word or words in Text1 to the IsPronounceable method and displays the resulting SpeechWordPronounceable constant.

Most correctly spelled words will be known and pronounceable; most incorrectly spelled words will be unknown and pronounceable. The example begins with a word which is pronounceable, even though it is misspelled.
