Microsoft Speech API 5.3

SpeechVoiceSpeakFlags Enum

The SpeechVoiceSpeakFlags enumeration lists flags that control the SpVoice.Speak method.

Elements

  • SVSFDefault
    Specifies that the default settings should be used. The defaults are:
    • To speak the given text string synchronously (override with SVSFlagsAsync),
    • Not to purge pending speak requests (override with SVSFPurgeBeforeSpeak),
    • To parse the text as XML only if the first character is a left-angle-bracket (override with SVSFIsXML or SVSFIsNotXML),
    • Not to persist global XML state changes across speak calls (override with SVSFPersistXML), and
    • Not to expand punctuation characters into words (override with SVSFNLPSpeakPunc).
  • SVSFlagsAsync
    Specifies that the Speak call should be asynchronous. That is, it will return immediately after the speak request is queued.
  • SVSFPurgeBeforeSpeak
    Purges all pending speak requests prior to this speak call.
  • SVSFIsFilename
    The string passed to the Speak method is a file name rather than text. As a result, the string itself is not spoken but rather the file the path that points to is spoken.
  • SVSFIsXML
    The input text will be parsed for XML markup.
  • SVSFIsNotXML
    The input text will not be parsed for XML markup.
  • SVSFPersistXML
    Global state changes in the XML markup will persist across speak calls.
  • SVSFNLPSpeakPunc
    Punctuation characters should be expanded into words (e.g. "This is it." would become "This is it period").
  • SVSFParseSapi
    Force XML parsing as MS SAPI.
  • SVSFParseSsml
    Force XML parsing as W3C SSML.
  • SVSFParseAutoDetect
    The TTS XML format is auto-detected. This is the default if none of these TTS XML format values are present in the bit-field.
  • SVSFNLPMask
    Flags handled by SAPI (as opposed to the text-to-speech engine) are set in this mask.
  • SVSFParseMask
    SVSFParseSapi|SVSFParseSsml
  • SVSFVoiceMask
    This is an existing SAPI 5.1 mask that has every flag bit set. In 5.3, it has been extended to contain SVSFParseMask.
  • SVSFUnusedFlags
    This mask has every unused bit set.
