Feature learning for efficient ASR-free keyword spotting in low-resource languages

no code implementations13 Aug 2021 Ewald van der Westhuizen, Herman Kamper, Raghav Menon, John Quinn, Thomas Niesler

We show that, using these features, the CNN-DTW keyword spotter performs almost as well as the DTW keyword spotter while outperforming a baseline CNN trained only on the keyword templates.

Automatic Speech Recognition for Humanitarian Applications in Somali

no code implementations23 Jul 2018 Raghav Menon, Astik Biswas, Armin Saeb, John Quinn, Thomas Niesler

We present our first efforts in building an automatic speech recognition system for Somali, an under-resourced language, using 1. 57 hrs of annotated speech for acoustic model training.

Fast ASR-free and almost zero-resource keyword spotting using DTW and CNNs for humanitarian monitoring

no code implementations25 Jun 2018 Raghav Menon, Herman Kamper, John Quinn, Thomas Niesler

While the resulting CNN keyword spotter cannot match the performance of the DTW-based system, it substantially outperforms a CNN classifier trained only on the keywords, improving the area under the ROC curve from 0. 54 to 0. 64.
