  • TTS_MRK_SENTENCE (0x0001) for sentence markers
  • TTS_MRK_WORD (0x0002) for word markers
  • TTS_MRK_PHONEME (0x0004) for phoneme markers

  • TTS_MRK_PARAGRAPH (0x0200) for paragraph markers

How to set

Shown in precedence order (see Rules of parameter precedence):

Set in a VoiceXML application, using the switts.marker_mode property in a <property> element.

Set in the voice browser, set as switts.marker_mode using the Vendor-Specific-Parameters header in a SPEAK method.

In the application's session xml in the <speechsynth> section of <sessionparameters>.

In Management Station, set on the Vocalizer service. If not using Management Station, set in the Vocalizer configuration file (User-nvsxx.xml).

Usage

Rarely changed.

Do not use in MRCP environments. MRCP supports bookmarks, and all other markers would add overhead and simply be discarded.
