Comentarios

Se crea una instancia de StateChangedEventArgs cuando el SpeechSynthesizer objeto genera el StateChanged evento . Para obtener los valores del nuevo y anterior SynthesizerState, acceda a las State propiedades y PreviousState del controlador para el evento .

Propiedades

PreviousState	Obtiene el estado de SpeechSynthesizer antes del evento StateChanged.
State	Obtiene el estado de SpeechSynthesizer antes del evento StateChanged.
