Techniques for soundscape retrieval and synthesis
TL;DR: This dissertation examines the application of several computational tools in the realms of digital signal processing, multimedia information retrieval, and computer music synthesis to the analysis of the soundscape.
Proceedings ArticleDOI
A brief survey of time- and frequency-domain adaptive filters
TL;DR: This tutorial session paper provides a brief survey of adaptive signal processing methods and applications and provides information and references on several applications including system identification, linear prediction, noise cancellation, and adaptive arrays.
Proceedings ArticleDOI
A Scalable Bandwidth Extension Algorithm
Visar Berisha,Andreas Spanias +1 more
TL;DR: Objective and subjective evaluations indicate that the proposed speech coding method performs at a lower average bit rate when compared to other similar algorithms while improving speech quality.
Journal ArticleDOI
Multiple Kernel Sparse Representations for Supervised and Unsupervised Learning
TL;DR: In this paper, the authors proposed to perform sparse coding and dictionary learning in the multiple kernel space, where the weights of the ensemble kernel are tuned based on graph-embedding principles such that class discrimination is maximized.
Journal ArticleDOI
Articulation constrained learning with application to speech emotion recognition
TL;DR: The proposed discriminative learning method for emotion recognition using both articulatory and acoustic information is proposed, and it is shown that the proposed method is more effective at distinguishing happiness from other emotions.
