Public propertyActionReturns the requested speech synthesizer action.
Public propertyDurationReturns the desired time for rendering a TextFragment
Public propertyEmphasisReturns instructions on how to emphasize a TextFragment.
Public propertyLangIdReturns the language supported by the current FragmentState.
Public propertyPhonemeReturns phonetic information for a TextFragment

  NameDescription
Public methodEquals(FragmentState)Determines if a given instance of FragmentState is equal to the current instance of FragmentState.
Public methodEquals(Object)Determines if a given object is an instance FragmentState equal to the current instance of FragmentState. (Overrides ValueType.Equals(Object).)
Public methodGetHashCodeReturns the hash code for this instance. (Overrides ValueType.GetHashCode().)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodToStringReturns the fully qualified type name of this instance. (Inherited from ValueType.)

  NameDescription
Public operatorStatic memberEqualityDetermines if two instances of FragmentState describes the same TextFragment state.
Public operatorStatic memberInequalityDetermines if two instances of FragmentState describes the different TextFragment state.

FragmentState instances are obtained from the State on TextFragment objects.

The information in FragmentState is obtained by parsing the attributes decorating speech text in the Synthesize Speech Markup Language (SSML) used as an input to a synthesis engine.

A FragmentState object can exist for any synthesizer action request as specified by its Action property. However, the meaning of its members may change for different actions. For more information on synthesize actions, see TtsEngineAction for more information about specifying synthesizer actions.

  • Specification and control of the quality of the spoken output is largely handled through the Prosody, Emphasis, and Duration

  • Phonetic, language, and linguist structure information is available through LangId, Phoneme, and SayAs.
