1. A computer-implemented method for improving performance of a speech recognition system, comprising:
- obtaining n-best hypotheses as an output of a speech recognition task performed by automatic speech recognition (ASR) for an utterance received by the speech recognition system;
combining the n-best hypotheses horizontally in a predetermined order with a separator between each pair of hypotheses to provide combined n-best hypotheses represented as a single text data structure, wherein each separator is set based on a classification algorithm of a classifier of the speech recognition system; and
outputting the single text data structure as an input to the classifier.

Abstract
A computer-implemented method for generating an input for a classifier. The method includes obtaining n-best hypotheses which is an output of an automatic speech recognition (ASR) for an utterance, combining the n-best hypotheses horizontally in a predetermined order with a separator between each pair of hypotheses, and outputting the combined n-best hypotheses as a single text input to a classifier.

16. A computer program product, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions executable by a computer to cause the computer to perform a method for improving performance of a speech recognition system, the method comprising:
-
obtaining n-best hypotheses as an output of a speech recognition task performed by automatic speech recognition (ASK) for an utterance received by a speech recognition system; combining the n-best hypotheses horizontally in a predetermined order with a separator between each pair of hypotheses to provide combined n-best hypotheses represented as a single text data structure, wherein each separator is set based on a classification algorithm of a classifier of the speech recognition system; and outputting the single text data structure as an input to the classifier. - View Dependent Claims (18, 19, 20)
