Elements

SPF_DEFAULT

Specifies that the default settings should be used.  The defaults are:

• Speak the given text string synchronously
• Not purge pending speak requests
• Parse the text as XML only if the first character is a left-angle-bracket (<)
• Not persist global XML state changes across speak calls
• Not expand punctuation characters into words.

To override this default, use the other flag values given below.

SPF_ASYNC

Specifies that the Speak call should be asynchronous. That is, it will return immediately after the speak request is queued.

SPF_PURGEBEFORESPEAK

Purges all pending speak requests prior to this speak call.

SPF_IS_FILENAME

The string passed to ISpVoice::Speak is a file name, and the file text should be spoken.

SPF_IS_XML

The input text will be parsed for XML markup.

SPF_IS_NOT_XML

The input text will not be parsed for XML markup.

SPF_PERSIST_XML

Global state changes in the XML markup will persist across speak calls.

SPF_NLP_SPEAK_PUNC

Punctuation characters should be expanded into words (e.g. "This is a sentence." would become "This is a sentence period").

SPF_NLP_MASK

This mask is used to remove the SAPI handled flags before ISpTTSEngine::Speak is called. The only flag which the TTS engine must handle is SPF_NLP_SPEAK_PUNC.

SPF_VOICE_MASK

This mask has every flag bit set.

SPF_UNUSED_FLAGS

This mask has every unused bit set.
