| Challenge: | 'Low-resourced'-ness is a complex problem that goes beyond data availability and reflects systemic problems in society. |
| Approach: | They propose to use machine translation to scale to low-resourced languages by using a dataset and a benchmarking system to measure their resource use. |
| Outcome: | The proposed approach allows participants without formal training to make a unique scientific contribution. |
A phonetic model of non-native spoken word processing (2021.eacl-main)
Copied to clipboard
| Challenge: | Compared to native speakers, non-native speakers perform differently in a variety of tasks related to auditory language processing, both at the phone and at the word level. |
| Approach: | They train a computational model of phonetic learning which has no access to phonology on either one or two languages and test it on a spoken word processing task. |
| Outcome: | The proposed model exhibits predictable behaviors on phone-level and word-level discrimination tasks and on a spoken word processing task. |
Pre-training on high-resource speech recognition improves low-resource speech-to-text translation (N19-1)
Copied to clipboard
| Challenge: | Pre-training on high-resource automatic speech recognition (ASR) tasks improves ST performance even when source language is low-resourced. |
| Approach: | They propose a method to improve direct speech-to-text translation when source language is low-resource . they pre-train model on high-res automatic speech recognition task and fine-tune parameters for ST . |
| Outcome: | The proposed approach improves Spanish English ST even when the source language is low-resource . the pre-trained encoder accounts for most of the improvement, the authors show . |
