Keyword spotting (KWS) is an important speech processing component for smart devices with voice assistance capability. In this paper, we investigate if Kolmogorov-Arnold Networks (KAN) can be used to enhance the performance of KWS. We explore various approaches to integrate KAN for a model architect…
A keyword spotting (KWS) engine continuously running on the device is exposed to various speech signals that are usually unseen beforehand. It is a challenging problem to build a small-footprint and high-performing KWS model with robustness under different acoustic environments. In this paper, we ex…
In this paper, we introduce spatial attention for refining the information in multi-direction neural beamformer for far-field automatic speech recognition. Previous approaches of neural beamformers with multiple look directions, such as the factored complex linear projection, have shown promising re…
Emotions modulate speech acoustics as well as language. The latter influences the sequences of phonemes that are produced, which in turn further modulate the acoustics. Therefore, phonemes impact emotion recognition in two ways: (1) they introduce an additional source of variability in speech signal…
Emotion is expressed over both speech and song. Previous works have found that although spoken and sung emotion recognition are different tasks, they are related. Classifiers that explicitly utilize this relatedness can achieve better performance than classifiers that do not. Further, research in sp…
