SPTEXTSELECTIONINFO

SPTEXTSELECTIONINFO combines text selection information that the speech recognition (SR) engine can use to improve recognition accuracy (using ISpRecoGrammar::SetWordSequenceData() and ISpRecoGrammar::SetTextSelection()). Applications built on the Speech Platform will typically not use this struct.
