PhonemeReachedEventArgs Class

Definition

Returns data from the PhonemeReached event.

public ref class PhonemeReachedEventArgs : System::Speech::Synthesis::PromptEventArgs
public class PhonemeReachedEventArgs : System.Speech.Synthesis.PromptEventArgs
type PhonemeReachedEventArgs = class
    inherit PromptEventArgs
Public Class PhonemeReachedEventArgs
Inherits PromptEventArgs
Inheritance

Examples

The following example is part of a Windows Forms application that writes the information returned by the PhonemeReached event to a text box. The phonemes are characters from the International Phonetic Alphabet (IPA).

Note

The first and last characters returned by PhonemeReachedEventArgs are opening and closing characters that enclose but do not represent phonemes that constitute a word or phrase. This example returns five characters, but only the middle three characters are phonemes that represent the word "theme": one for the "th" sound, one for the "e" sound, and one for the "m" sound .
