New Measures of Effectiveness for Human Language Technology.

摘要

Research in human language technology (HLT) has made great progress in the past few years. The general field of HLT encompasses a wide range of algorithms and applications dedicated to processing human speech and written communication. The two specialized HLT fields we address here, from the perspective of the needs of the Defense Department, are (1) machine translation systems, which convert text and speech files from one human language to another, for example, from Arabic into English, and (2) speech-to-text (STT) systems, which produce text transcripts when given audio files of human speech as input. Both processes are subject to machine errors and may produce varying levels of garbling in their output.
