Audio quality issue for automatic speech assessment

Recently, in the language testing field, automatic speech recognition (ASR) technology has been used to automatically score speaking tests. This paper investigates the impact of audio quality on ASR-based automatic speaking assessment. Using the read speech data in the International English Speaking Test (IEST) practice test, we annotated audio quality and compared scores rated by humans, speec...

An Assessment of the Accuracy of Automatic Evaluation in Summarization

Automatic evaluation has greatly facilitated system development in summarization. At the same time, the use of automatic evaluation has been viewed with mistrust by many, as its accuracy and correct application are not well understood. In this paper we provide an assessment of the automatic evaluations used for multi-document summarization of news. We outline our recommendations about how any e...

Predicting word accuracy for the automatic speech recognition of non-native speech

We have developed an automated method that predicts the word accuracy of a speech recognition system for non-native speech, in the context of speaking proficiency scoring. A model was trained using features based on speech recognizer scores, function word distributions, prosody, background noise, and speaking fluency. Since the method was implemented for non-native speech, fluency features, whi...

The Effect of Knowledge of Result Feedback Timing on Speech Motor Learning in Healthy Adults

Objectives: The current study mainly aimed at studying the effect of Knowledge of Result (KR) feedback timing and result-estimation opportunity before receiving delayed KR on learning a new speech motor skill in monolingual healthy adults.  Methods: Thirty-nine Persian healthy adults were randomly divided into three groups. Each group received immediate KR, delayed KR (after eight seconds), or...
