A Tale of Two Tasks: Detecting Children's Off-Task Speech in a Reading Tutor
How can an automated tutor detect children’s off-task utterances? To answer this question, we trained SVM classifiers on a corpus of 495 children’s 36,492 computerassisted oral reading utterances. On a test set of 620 utterances by 10 held-out readers, the classifier correctly detected 88% of off-task utterances and misclassified 17% of on-task utterances as off-task. As a test of generality, w...
متن کاملSyllable and language model based features for detecting non-scorable tests in spoken language proficiency assessment applications
This work introduces new methods for detecting non-scorable tests, i.e., tests that cannot be accurately scored automatically, in educational applications of spoken language proficiency assessment. Those include cases of unreliable automatic speech recognition (ASR), often because of noisy, off-topic, foreign or unintelligible speech. We examine features that estimate signalderived syllable inf...
متن کاملOff-line Arabic Handwritten Recognition Using a Novel Hybrid HMM-DNN Model
In order to facilitate the entry of data into the computer and its digitalization, automatic recognition of printed texts and manuscripts is one of the considerable aid to many applications. Research on automatic document recognition started decades ago with the recognition of isolated digits and letters, and today, due to advancements in machine learning methods, efforts are being made to iden...
متن کاملDetection of Speaker Direction Based on the On-and-Off Microphone Combination for Entertainment Robots
An important function of entertainment robots is voice communication with humans. For realizing them, accurate speech recognition and a speaker-direction detection mechanism are necessary. The directnoise problem is serious in such speech processing. The microphone attached to the robot body receives not only human voices but also motor and mechanical noises directly. The direct noises are ofte...
متن کاملSemantic Similarity for Detecting Recognition Errors in Automatic Speech Transcripts
Browsing through large volumes of spoken audio is known to be a challenging task for end users. One way to alleviate this problem is to allow users to gist a spoken audio document by glancing over a transcript generated through Automatic Speech Recognition. Unfortunately, such transcripts typically contain many recognition errors which are highly distracting and make gisting more difficult. In ...
