15. A computer-readable storage device having instructions stored which, when executed by a computing device, cause the computing device to perform operations comprising: receiving speech; and while continuing to receive the speech: identifying a starting point associated with the speech; identifying content of the speech received so far, to yield identified content; predicting a stability of the identified content; and identifying an end point associated with the speech, wherein the end point is a pinch node in a content lattice; and returning a result based on the stability between the starting point and the end point.
