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.
