3、rge vocabulary speech recognition applications. The persistent presence of ASR errors have intensified the need to find alternative techniques to automatically detect and correct such errors. The correction of the transcription errors is very crucial not only to improve the speech recognition accura

In this paper, basic principles of ASR evaluation are first summarized, and then the state of the current ASR errors detection and correction research is reviewed. We focus

Introduction Automatic Speech Recognition (ASR) systems aims at converting a speech signal into a sequence of words either for text-based communi

The purpose of evaluating ASR systems is to simulate human judgement of the performance of the systems in order to measure their usefulness and assess the remaining difficulties and especially when comparing systems. The standard metric of ASR evaluation is the Word Error Rate, which is defined as the proportion of word errors to words processed. ASR has matured to the point of commercial applications by providing transcription with an acceptable lev
