SpeakToFile

(VoiceTalk Module)

Description:	Executes on the speech thread to speak the supplied text to a .wav format audio file.
Returns:	Nothing
Usage:	Script Only.
Function Groups:	Speech and Sound, File I/O
Related to:	Configure \| GetDevices \| GetVoices \| Reset \| ShowLexicon \| Speak \| VoiceTalk
Format:	VoiceTalkStream\SpeakToFile(Phrase, Flags, Filename, Quality[, Result])
Parameters:

VoiceTalkStream

Required. A speech stream returned from VoiceTalk that you wish to speak the given phrase.

Phrase

Required. Any text expression that will be spoken on a specified stream.
This is limited to the number of characters specified by MaxSpeakToFileLength, defaulting to 1000.

Flags

Required. A parameter to specify speaking flags to the stream. All text will be spoken asynchronously (i.e. the function will not wait for the speech to complete speaking). Flags can be used to specify other parsing of the text. The values for Flags can be any combination of the following

Flags	Meaning
0	Use default settings (speak asynchronously)
1	Speak asynchronously.
2	Purge speaking queue before speaking text. This cancels all pending and current speech, and then immediately begins speaking the new text.
4	Regard the Text parameter as a filename, and speak the contents of that file.
8	Parse text for XML markup.
16	Do not parse text for XML markup.
32	Any XML state changes in the text will persist across any future VoiceTalk\Speak calls.
64	Punctuation characters should be spoken (i.e. "Hello, there." would be spoken as "Hello comma there period").

As indicated above, an Invalid value, or a value of "0" or "1" for the Flags parameter will have the same result.

Filename

Required. The name of the .wav file to speak into (e.g. "c:\folder\file.wav")

Quality

Required. The format quality to use, as defined by the following table:

Quality	Format	Quality	Format
-1	SAFTdefault
4	SAFT8kHz8BitMono	5	SAFT8kHz8BitStereo

36	SAFT48kHz8BitMono	37	SAFT48kHz8BitStereo
38	SAFT48kHz16BitMono	39	SAFT48kHz16BitStereo

Result

Required. A pointer to a flag to set when done. This should be 0 for OK or 1 for an error.

Comments:

The text may include embedded XML tags as described in the documentation for the SAPI speech engine being used.
Multiple calls to this function will be queued.
Calls to this module will fail if the VoiceTalk instance was not configured for VTSFileOutput.
