Mathematical Content Browsing for Print-Disabled Readers Based on Virtual-World Exploration and Audio-Visual Sensory substitution

Autor: Kruger, Rynhardt, de Wet, Febe, Niesler, Thomas

Documents containing mathematical content remain largely inaccessible to blind and visually impaired readers because they are predominantly published as untagged PDF which does not include the semantic data necessary for effective accessibility. We p

Multilingual Bottleneck Features for Improving ASR Performance of Code-Switched Speech in Under-Resourced Languages

Autor: Padhi, Trideba, Biswas, Astik, De Wet, Febe, van der Westhuizen, Ewald, Niesler, Thomas

In this work, we explore the benefits of using multilingual bottleneck features (mBNF) in acoustic modelling for the automatic speech recognition of code-switched (CS) speech in African languages. The unavailability of annotated corpora in the langua

Semi-supervised Development of ASR Systems for Multilingual Code-switched Speech in Under-resourced Languages

Autor: Biswas, Astik, Yılmaz, Emre, de Wet, Febe, van der Westhuizen, Ewald, Niesler, Thomas

This paper reports on the semi-supervised development of acoustic and language models for under-resourced, code-switched speech in five South African languages. Two approaches are considered. The first constructs four separate bilingual automatic spe

Semi-supervised acoustic model training for five-lingual code-switched ASR

Autor: Biswas, Astik, Yılmaz, Emre, de Wet, Febe, van der Westhuizen, Ewald, Niesler, Thomas

This paper presents recent progress in the acoustic modelling of under-resourced code-switched (CS) speech in multiple South African languages. We consider two approaches. The first constructs separate bilingual acoustic models corresponding to langu

Building a Unified Code-Switching ASR System for South African Languages

Autor: Yılmaz, Emre, Biswas, Astik, van der Westhuizen, Ewald, de Wet, Febe, Niesler, Thomas

We present our first efforts towards building a single multilingual automatic speech recognition (ASR) system that can process code-switching (CS) speech in five languages spoken within the same population. This contrasts with related prior work whic
