TtsGetSupportedParams

Return the list of all the supported parameter names for TtsSetParamsEx and TtsGetParamEx.

TTSRETVAL TtsGetSupportedParams(

 HTTSINSTANCE hTtsInst,

 LH_BOOL bUseMrcpNames,

 VXIVector * pSupportedParams);

Argument	Description
hTtsInst	[in] Handle to a TTS engine instance.
bUseMrcpNames	[in] LH_TRUE gives a list of MRCP parameter names (aliases for the native Vocalizer parameter names). LH_FALSE gives a list of the native Vocalizer parameter names (excluding the MRCP parameter name aliases).
pSupportedParams	[out] Application provided VXIVector that gets populated with the parameter names, where each element is a VXIString that gives a parameter name.

This function is helpful for supporting blind parameter pass-through for protocols like MRCP, making new Vocalizer parameters accessible over those protocols without having to change middleware.

MRCP parameter names are case-insensitive, but Vocalizer native parameter names are case-sensitive.
