  • Article

The TF_LMLATTELEMENT structure contains information about a lattice element. A lattice element is used in speech recognition. This structure is used with the IEnumTfLatticeElements::Next method.

Syntax

typedef struct TF_LMLATTELEMENT {
  DWORD dwFrameStart;
  DWORD dwFrameLen;
  DWORD dwFlags;
  union {
    INT iCost;
  };
  BSTR  bstrText;
} TF_LMLATTELEMENT;

Members

dwFrameStart

Contains the starting offset, in 100-nanosecond units, of the element relative to the start of the phrase.

dwFrameLen

Contains the length, in 100-nanosecond units, of the element.

dwFlags

Not currently used.

iCost

Specifies the actual confidence for this element. This can be one of the following values.

Value Meaning
SP_LOW_CONFIDENCE The speech engine has low confidence in the element.
SP_NORMAL_CONFIDENCE The speech engine has normal confidence in the element.
SP_HIGH_CONFIDENCE The speech engine has high confidence in the element.
