Papers with classifier models
Classifying Sluice Occurrences in Dialogue (L18-1)
Copied to clipboard
| Challenge: | Ellipsis is an important challenge for natural language processing systems, says a new paper . previous work on ellipsis focused on news data, but sluicing presents a challenge for dialogue systems . |
| Approach: | They describe a corpus of 4100 sluice occurrences from the NYTimes Gigaword corpus . they build a classifier model to automatically classify slujce . |
| Outcome: | The proposed corpus contains 4100 sluice occurrences, with an accuracy of 67% . the work will support empirical research into slujcing in dialogue systems . |
AccentDB: A Database of Non-Native English Accents to Assist Neural Speech Recognition (2020.lrec-1)
Copied to clipboard
| Challenge: | aaron e. sanchez and joe saunders: automatic speech recognition still faces a major challenge . they say accents are a way of pronouncing a language, and speakers always have manner of speaking . esassen: accents can be used to identify non-native speakers of a speech . |
| Approach: | They propose to create a database of speech samples in non-native accents for ASR testing . they also propose to introduce accent neutralization of non- native accents to native accent . |
| Outcome: | The proposed model is compared against human-labelled accent classes and is generalized against human data. |
Lexical Tone Recognition in Mizo using Acoustic-Prosodic Features (2020.lrec-1)
Copied to clipboard
| Challenge: | Mizo is an under-studied Tibeto-Burman tonal language of the Northeast of India. |
| Approach: | They propose to use acoustic-prosodic parameters to automatically recognize four phonological tones in Mizo using a set of features computed from Fundamental Frequency contours. |
| Outcome: | The proposed model performs better than the existing classifiers in recognizing four phonological tones in Mizo using acoustic-prosodic parameters. |
