LogLikelihood()

virtual BaseFloat LogLikelihood ( int32  frame, int32  index  )

inlinevirtual

Returns the log likelihood, which will be negated in the decoder.

The "frame" starts from zero. You should verify that NumFramesReady() > frame before calling this.

Reimplemented from DecodableAmSgmm2.
