Analysis of Mismatched Transcriptions Generated by Humans and Machines for Under-Resourced Languages

Authors: 
Van Hai Do, Nancy Chen, Lim Boon Pang, Mark Hasegawa-Johnson
Publication: 
INTERSPEECH - HLT TOP CONFERENCE

Strategic Thrust: 
Intelligence
Abstract: 
When speech data with native transcriptions are scarce in an under-resourced language, automatic speech recognition (ASR) must be trained using other methods. Semi-supervised learning first labels the speech using ASR... Read more ›

Rescoring Hypothesized Detections of Out-of-Vocabulary Keywords Using Subword Samples

Authors:

Abstract: 
Rescoring hypothesized detections, using keyword's audio samplesextracted from training data, is an effective way to improvethe performance of a Keyword Search (KWS) system. Unfortunatelysuch rescoring framework cannot be applied directlyto... Read more ›

Detecting Mispronunciations of L2 Learners and Providing Corrective Feedback Using Knowledge-guided and Data-driven Decision Trees

Authors:

Strategic Thrust: 
Intelligence
Abstract: 
Recent advances in the brain-computer interfaces (BCIs) have demonstrated the inference of movement related activity using non-invasive EEG. However, most of the sensor- space approaches that study sensorimotor rhythms using... Read more ›
