Nkululeko: A Tool For Rapid Speaker Characteristics Detection (2022.lrec-1)
Copied to clipboard
| Challenge: | Nkululeko is a software tool that lets users perform semi-supervised machine learning experiments in the speaker characteristics domain. |
| Approach: | They propose a software tool called Nkululeko that lets users perform semi-supervised machine learning experiments in the speaker characteristics domain. |
| Outcome: | The proposed tool is based on audformat, a speech database metadata description . it supports best practise and fast setup of experiments without programming skills . |
A Comparative Cross Language View On Acted Databases Portraying Basic Emotions Utilising Machine Learning (2022.lrec-1)
Copied to clipboard
| Challenge: | Since several decades emotional databases have been recorded by various laboratories. |
| Approach: | They propose to model similarity as performance in cross database machine learning experiments and to analyze a manually picked set of four acoustic features that represent different phonetic areas. |
| Outcome: | The proposed sets of features represent different phonetic areas and are comparable across languages. |
