Interspeech 20232023Neural transducer ASR models achieve state of the art accuracy on many tasks, however rare word recognition poses a particular challenge as models often fail to recognise words that occur rarely, or not at all, in the training data. Methods of contextual biasing, where models are dynamically adapted to bias their outputs towards a given list of relevant words and phrases, have been shown to be effective

Interspeech 20232023Conformer is an extension of transformer-based neural ASR models whose fundamental component is the self-attention module. In this paper, we show that we can remove the self-attention module from Conformer and achieve the same or even better recognition performance for utterances whose length is up to around 10 seconds. This is particularly important for streaming interactive voice assistants as input is

Interspeech 20232023Contextual biasing (CB) is an effective approach for contextualising hidden features of neural transducer ASR models to improve rare word recognition. CB relies on relatively large quantities of relevant human annotated natural speech during training, limiting its effectiveness in low-resource scenarios. In this work, we propose a novel approach that reduces the reliance on real speech by using synthesised

Interspeech 20232023Voice assistant accessibility is generally overlooked as today’s spoken dialogue systems are trained on huge corpora to help them understand the ‘average’ user. This raises frustrating barriers for certain user groups as their speech shifts from the average. People with dementia pause more frequently mid-sentence for example, and people with hearing impairments may mispronounce words learned post-diagnosis

KDD 20232023Graph neural networks (GNNs) have shown high potential for a variety of real-world, challenging applications, but one of the major obstacles in GNN research is the lack of large-scale flexible datasets. Most existing public datasets for GNNs are relatively small, which limits the ability of GNNs to generalize to unseen data. The few existing large-scale graph datasets provide very limited labeled data.
